Svchost loads windows 7 RAM solution. How else can you fix the problem

02.05.2019 Iron

Users of the seventh modification of Windows very often face a problem when a certain Windows 7 Svchost.exe process loads the processor. The solution to fix the problem, as it turns out, lies on the surface. However, in order to determine exactly which technique to use to correct the situation, you first need to figure out what this process and the associated service components are, since disabling some of them can provoke not only incorrect operation of the OS, but also the appearance more unpleasant symptoms (even a blue screen is not excluded).

Svchost: what is this process?

Since the problems of increased load of this service are most often observed in Windows 7, and in systems of later releases, they are almost never encountered, when considering all aspects, we will start from the seventh modification.

What is this component that consumes such an incredible amount of system resources? This is a specialized launcher for system and user programs, which, according to the developers from Microsoft, in theory, should reduce the load on the system at the time of launching programs and their executable components, for example, presented in the form of dynamic libraries loaded at the start of an executable component as additional objects into RAM.

In simpler and more understandable language, in Windows 7 the system itself does not need to launch each application as a separate process, since only one main component is used for this, due to which all programs start, as if tied to it. And the Svchost process is a kind of intermediary bridge between the program being launched and the main system component responsible for starting it. That is, all starting programs and processes through this component are connected to a single launch service.

Why are there too many processes of the same name in the Task Manager?

But the main start service is not displayed in the same "Task Manager". In it you can see just the processes of the same name Svchost, of which there can be about four in a normal idle state, and even more if there are running programs.

Thus, if Svchost overloads the processor and memory, Windows 7 simply processes too many active background (system) and user applications at the moment. But many of them can be quite resource-intensive (take at least AutoCAD or programs for processing video in real time). In such situations, usually in Windows 7 Svchost loads the processor by 50% (maybe a little more). If peak loads are noticed, when the operating system freezes and stops responding to any user actions, you will have to find out the reasons why this is happening.

Windows 7: Svchost loads the processor by 100%. Why?

As for the reasons themselves, there can be quite a lot of them, and not always such situations can be triggered by system failures (although, unfortunately, one cannot do without them).

But back to the situation when in Windows 7 Svchost.exe loads the processor too much. The most likely reasons for this phenomenon are the following:

short-term failures of system processes;
viral infection;
problems with the system update service;
Too many or failures of related services and system components;
incorrect operation of the tunnel adapter;
problems with the SuperFetch component;
a large amount of computer junk.

The list contains only the main aspects, which will be further considered. And for situations when in Windows 7 Svchost.exe loads the processor, a solution for each specific case will be proposed precisely based on what was the root cause of such an unpleasant situation. But first things first.

Windows 7: Svchost (netsvcs) overloads the processor: a solution to quickly reduce the load

Many users quite rightly believe that in the simplest case, you can reduce the load by terminating all Svchost processes in the "Task Manager". Yes, indeed, it can be done. But in this case, this is just a temporary measure (and in the presence of viruses, it does not help at all).

The same goes for a regular reboot of the operating system. After the restart, there will be no increased resource consumption, of course, but the process itself in the form of four (at least) executable files in the Task Manager will still be present. This system component is automatically loaded with the system, and it is impossible to disable it using standard methods, say, using the startup menu.

Checking the system for viruses

But there are even worse situations. Suppose, in Windows 7, Svchost overloads the processor. What if the user sees in the "Task Manager" a dozen and a half lines with a link to the same executable file, and the CPU load reaches its maximum peak values?

Apparently, this is the first sign of a virus impact, since many threats are disguised just under the system process and are capable of simultaneously launching several copies of their own. This will require manual user intervention with the launch of some powerful portable utility for a deep scan of the computer for viruses.

It is best to use the Dr. Web CureIt !, but the best option would be to boot from removable media with the Kaspersky Rescue Disk utility written on it. It is this program that is the undisputed leader, since it starts even before the OS is loaded, it can detect and neutralize threats that are deeply rooted not only in the operating system, but also in RAM.

You can determine that the selected process belongs to a virus threat by the additional attribute of the user name. There can be only two of them: either NETWORK SERVICE or LOCAL. If the user observes any other description, the conclusion is obvious: this is a virus disguised as the original process. In principle, before using the anti-virus utilities, you can use the PCM to access the directory where the accompanying process file is located and, if possible, delete it manually.

Troubleshoot system update issues

But viruses are not always the reason that in Windows 7 Svchost (netsvcs) overloads the processor. Very often this is due to failures of the offline update installer ("Update Center").

For example, a package was not downloaded when it was downloaded. So it turns out that the system service is trying to load it up (this starts the Svchost process, which corresponds to it), but there is no result. On the other hand, the "Update Center" itself may for some reason work incorrectly. It may require a restart.

In this case, the services section (services.msc) is first called, in which you need to find the corresponding component, enter the edit section, stop the service and set the disabled startup type for it. After that, the system needs to be rebooted and the service reactivated with an automatic start type.

Disable or stop related services

If none of the above helped, and in Windows 7 Svchost loads the processor, the solution can be reduced to looking at which processes are associated with the executable file, and, if possible, disable them.

For this, the same "Task Manager" is used, in which, through the PCM on each process, you need to look at the corresponding service, go to the main section and temporarily disable all processes, as it was shown just above.

Fixing Tunnel Adapter Issues

Rarely, but sometimes non-standard situations associated with the work of the so-called can occur. It is because of its malfunction in Windows 7 that Svchost loads the processor. The solution consists in adjusting its parameters or even completely shutting it down.

To do this, it is best to use the command console, invoked through the Run menu using the cmd command. Next, the lines shown in the image above are written in the console, and after they are executed, a complete reboot of the computer system is performed.

from garbage

There is a simpler problem, but just as intrusive. If in Windows 7 Svchost loads the processor, the solution may be somehow related to computer garbage, for example, in terms of the lack of free disk space for the normal functioning of the operating system itself (usually it is recommended to keep approximately 10% of the total volume free in the system partition ).

To begin with, you can clean up the disk with a standard tool, if you go to the properties of the section through the RMB menu in the "Explorer". On the other hand, some residual files are not removed after uninstalling programs in this way. But finding them yourself is quite problematic. Alternatively, you can use special cleaners or optimizers (CCleaner, Advanced SystemCare, Glary Utilities, or something similar).

SuperFetch problems

Another of the most common situations many experts call problems with the SuperFetch service. To disable it, you can use the methods proposed above, with entering the services section, stopping the process and changing the startup type.

However, most often the problem is not even this, but the overflow of the corresponding Prefetch directory, which is located at the root of the system. It is because of him that Svchost loads the processor in Windows 7. The solution is the simplest: delete the directory yourself, end all Svchost.exe processes in the "Task Manager" and reboot. After restarting, you do not need to reactivate the disabled service. Most users, in general, do not need it at all, and among other things, it is quite "gluttonous" in terms of the consumption of system resources, which on weak computer configurations leads to sad consequences.

If in the "Task Manager" there is an activation of the process with the name of the executable file wuauclt.exe, you need to find the SoftwareDistribution directory (OS root directory) and remove all subfolders and files from it, after which, as usual, restart the computer. You can also rename the original directory itself, assigning it a name with the addition of ".old" and reboot immediately even without deleting it.

Brief summary

That's all with regard to the main reasons for the appearance of increased loads on the central processor and RAM, as well as the main methods of eliminating them. True, in a certain sense, it is very difficult to say right away what provoked such a phenomenon. This can be done with confidence only in case of a virus infection or in the case when even the manual check for updates or their installation does not work in the Update Center. In all other situations, you will have to perform each action separately. Except for possible failures or damage to iron (in particular, this applies to RAM strips), at least one technique, but will give a positive effect in any case.

To be on the safe side, many experts recommend clearing the system event log, which contains the LOG files. It can be called through the "Run" console with the eventvwr line, and then use the cleanup points for the application, system, security and installation sections via the PCM. Upon completion of all actions, the system must be rebooted without fail.

If the proposed methods do not work for some reason, identical actions can be performed in Safe Mode by pressing F8 at startup.

Sometimes, when working on a computer, users notice that it has begun to slow down. Opening "Task Manager", they discover that the RAM or CPU is loading SVCHOST.EXE. Let's figure out what to do if the above process loads the RAM of a Windows 7 PC.

SVCHOST.EXE is responsible for the interaction of services with the rest of the system. Each of this process (and there are several running at the same time) serves a whole group of services. Therefore, one of the reasons for the problem under study may be an unoptimized OS setting. This is expressed in the launch of a large number of services at the same time or those of them that even in a single instance consume a large amount of resources. Moreover, they do not always really bring real benefit to the user.

Another reason for the "gluttony" of SVCHOST.EXE may be some kind of system failure in the PC. In addition, some viruses disguise themselves as this process and load RAM. Next, we will look at various ways to solve this problem.

Method 1: Disable Services

One of the main ways to reduce the load of SVCHOST.EXE on the PC's RAM is to disable unnecessary services.

First, let's determine which services load the system the most. Call "Task Manager"... To do this, click on "Taskbars" right-click ( PKM) and in the opened contextual list select "Start Task Manager"... Alternatively, you can use the combination Ctrl + Shift + Del.

In the opened window "Dispatcher" move to section "Processes".

In the section that opens, click on the button "Show processes of all ..."... Thus, you can view information not only related to your account, but also all profiles on this computer.

Further, in order to group together all SVCHOST objects for subsequent comparison of the load value, arrange all the elements of the list in alphabetical order by clicking on the field "Image name".

Then find the SVCHOST process group and see which one is using the most RAM. The given element in the column "Memory" the largest number will be.

Click on this object PKM and in the drop-down list, choose Go to Services.

A list of services opens. Those marked with a bar refer to the process selected in the previous step. That is, it is they who carry out the greatest load on the RAM. In the column "Description" their names are shown as they appear in Service Manager... Memorize or write them down.

Now you need to go to Service Manager to deactivate these objects. To do this, press "Services ...".

You can also open the desired tool using the window "Run"... Dial Win + R and enter in the opened field:

Then click "OK".

Will start Service Manager... It is here that there is a list of those objects, among which we have to deactivate a part. But you need to know which service you can disable and which one cannot. Even if a certain object belongs to the SVCHOST.EXE that loads the computer, this does not mean that it can be deactivated. Disabling some services may cause the system to crash or malfunction. Therefore, if you do not know which of them can be stopped, then before proceeding with further actions, check out our separate lesson, which is devoted to this topic. By the way, if you see in "Dispatcher" a service that is not included in the group of the problematic SVCHOST.EXE, but neither you nor Windows actually use it, then in this case it is also advisable to disable this object.
Highlight in Service Manager the object to be deactivated. On the left side of the window, click on the item "Stop".

The stop procedure will be performed.

After that in "Dispatcher" opposite the name of the stopped element status "Works" in a collumn "State" will be absent. This means that it is turned off.

But that is not all. If the column "Startup type" the value will be set opposite the element name "Automatically", then this means that the service will start automatically the next time the PC is restarted. In order to make a complete deactivation, double-click on its name with the left mouse button.

The properties window will open. Click on the item "Startup type" and from the list that appears, select "Disabled"... Following this action, press Apply and "OK".

Now the service will be completely deactivated and will not start itself even the next time the PC is restarted. This is evidenced by the presence of the inscription "Disabled" in a collumn "Startup type".

In the same way, disable other services that are associated with the RAM-loading SVCHOST.EXE process. However, do not forget that the element to be disabled should not be associated with important system functions or those capabilities that you personally need to work. After deactivation, you will see that the consumption of RAM by the SVCHOST.EXE process will significantly decrease.

Method 2: Disable Windows Update

On low-power computers, the problem with SVCHOST.EXE loading RAM may be related to the update function. This is a very important element of Windows, which allows you to always keep the OS up to date and patch vulnerabilities. But if "Update centre" starts to "eat" RAM through SVCHOST.EXE, you need to choose the lesser of two evils and deactivate it.

Click "Start" and go to "Control Panel".

Go to section "System and safety".

Open the section "Update centre…".

On the left side of the window that opens, click "Settings".

A window for managing update settings will open. Click on the dropdown "Important Updates" and choose an option "Do not check for availability ..."... Next, uncheck all the checkboxes in this window and click "OK".

Updates will be disabled, but you can also deactivate the corresponding service. To do this, move to Service Manager and find the element there Windows Update... After that, perform with him all those shutdown manipulations that were considered in the description Method 1.

It is important to understand that disabling updates will leave your system vulnerable. Therefore, if the power of your PC does not allow you to work with "Update Center", try to regularly perform manual installation of updates.

Method 3: System Optimization

The occurrence of the problem under study can cause clogging of the system or its incorrect configuration. In this case, you need to determine the immediate cause and take one or more of the following actions to optimize the OS.

One of the factors causing this problem may be a clogged system registry, which contains out-of-date or erroneous entries. In this case, it needs to be cleaned. For this purpose, you can use specialized utilities, for example,.

Defragmenting your hard drive may help to resolve this issue. This procedure can be performed both with the help and using the built-in Windows utility.

Method 4: Troubleshoot and troubleshoot

Various system crashes and problems can cause the problem described in this article. In this case, you need to try to fix them.

It is possible that a malfunction of the computer, which led to excessive consumption of OS resources by the SVCHOST.EXE process, was caused by a violation of the structure of system files. In this case, you need to check them for integrity using the built-in sfc utility, followed by restoration if necessary. This procedure is performed through Command line by introducing the command into it:

Another cause leading to the problem described above is errors on the hard disk. Checking the system for their presence is also carried out through Command line, by entering the expression there:

If the utility detects logical errors during scanning, it will try to fix them. In case of physical damage to the hard drive, you either need to contact the master or purchase a new hard drive.

Method 5: Eliminate viruses

Viruses can cause a load on the RAM via SVCHOST.EXE. In addition, some of them disguise themselves as an executable file with this name. If there is a suspicion of infection, it is necessary to urgently carry out the corresponding, which do not require installation. For example, you can use.

Scanning is recommended by starting the system using LiveCD or LiveUSB. You can also use another uninfected PC for this purpose. If the utility detects virus files, you need to follow the instructions that will be displayed in its window.

Unfortunately, it is not always possible to find a virus using antivirus utilities. If the scanning procedure with several antiviruses failed to detect malicious code, but you suspect that one of the SVCHOST.EXE processes was initiated by a virus, you can try to manually establish the identity of the executable file and, if necessary, delete it.

How to determine if the real SVCHOST.EXE or is it a virus masquerading as this file? There are three features of the definition:

Process user;
The location of the executable file;
File name.

The user on whose behalf the process is started can be viewed in "Task Manager" in the already familiar tab "Processes"... Opposite the name "SVCHOST.EXE" in column "User" one of three options should be displayed:

"System" (SYSTEM);
Network Service;
Local Service.

If you see the name of any other user there, then know that the process has been spoofed.

The location of the executable file of the process that consumes a large amount of system resources can be determined right there in "Task Manager".

Finally, as mentioned above, you need to check the name of the process. It should be exactly "SVCHOST.EXE" from first to last letter. If the name "SVCHOCT.EXE", "SVCHOST64.EXE" or any other, then know that this is a substitution.

Although sometimes attackers act even more cunningly to disguise themselves. They replace the letters "c" or "o" in the name with exactly the same characters in writing, but not in the Latin, but in the Cyrillic alphabet. In this case, the name will be visually indistinguishable, and the file itself may even be located in the System32 folder next to the original copy. In such a situation, you should be alarmed by the location of two files with the same name in the same directory. In Windows, this, in principle, cannot be, but in this case it turns out to be realized only by substituting symbols. With this state of affairs, one of the criteria for determining the authenticity of a file is its date. Typically, this item has an earlier modification date.

But how can you delete a fake file if it is detected if the antivirus utility does not help?

Attention! Only remove SVCHOST.EXE if you are 100% sure that it is not a genuine system file, but a fake. If you mistakenly delete the real one, it will break the system.

Method 6: System Restore

In the event that none of the above helped, you can perform the system recovery procedure, if you have one, or one that was created even before the problems with SVCHOST.EXE, which loads RAM. Next, we will look at how to normalize the functioning of Windows using resuscitation to a previously created point.

Click "Start" and click on the object "All programs".

Open the directory "Standard".

Enter the folder "Service".

Click on the item "System Restore".

The system recovery tool window is activated with introductory information. Just click here "Further".

In the next window, you need to select a specific restore point. There may be several of them in the system, but you need to stop the choice only on one. The main condition is that it was created before the problem with SVCHOST.EXE began to appear. It is advisable to select the most recent item by date that meets the above condition. To increase your choice, check the box next to "Show others ..."... After the desired object is selected, click "Further".

In the next window, to start the recovery procedure, just click the button "Ready"... But since after that the computer will be restarted, take care to close all active programs and save unsaved documents in order to avoid data loss.

Then the recovery procedure will be performed and the system will return to the state in which it was before SVCHOST.EXE started loading RAM.

The main disadvantage of this method is that you should not just have a restore point or a system backup - the time of its creation should not be later than the point from which the problems began to appear. Otherwise, the procedure loses its meaning.

There are several different reasons why SVCHOST.EXE can start loading computer memory into Windows 7. These can be system failures, incorrect configuration or virus infection. Accordingly, each of these reasons has a separate group of ways to eliminate it.

The first step is to try to disable applications one by one. Indeed, it is quite possible to overload a low-power device by simultaneously running several heavy-weight applications.

Second. Long-term active surfing of the Internet is often the cause of problems. The system is littered with hundreds of megabytes of temporary files. The registry is at a loss. There are two options here.
1. Run the cleaner and delete all unnecessary files, repair the registry and perform basic defragmentation.
2. Didn't it help? Then open System Restore and roll back to an earlier state. On one occasion, it is almost never possible to restore normal performance. Usually, no more than three restorations are sufficient.

And don't forget to create rollback points. Does the computer fly? Go to Recovery and create a return point. It will come in handy.

The next assumption is that a malicious virus has entered the computer. If possible, start scanning. You need to be patient, drink some tea, take a nap. In such a relaxed state of the system, scanning will take a long time.

Another classic cause of system overload is the svchost.exe process

What is it and why does it interfere with the work of the computer? The svchost.exe process is one of the auxiliary system services involved in many other tasks. The thing is useful, but sometimes buggy. What can disturb this process?
1. Physical damage to memory chips. A lot of dust has accumulated in the system unit. Service centers recommend vacuuming the inside of your computer at least once a year.
2. Errors when downloading automatic updates. For example, there were internet connection or power outages during the upgrade process. Facts were noted when the service packs themselves were originally supplied with bugs. Even Microsoft experts themselves admitted it.

In cases where problems are caused by unusable updates, it is recommended to go to the official Microsoft website and download a verified and reliable package, then install it yourself.

Viruses are often disguised as the svchost.exe process.

It is very convenient for hackers to present a virus or Trojan under the guise of the svchost.exe process. The system will throw a notification about an unknown error and while the user can still figure out the reasons. First you need to find out if the svchost.exe process is guilty? To do this, open the Windows Task Manager (Alt + Ctrl + Del) and go to the Processes tab.

There will be at least four svchost.exe processes. Now see the load rate for each process. If some svchost.exe process has a load close to 100%, this is the culprit. What's next?
1. It is always recommended to restart the system first. More often than not, the problems disappear.
2. If everything happens again, open the Task Manager again and terminate the overloaded svchost.exe process. To do this, open the context menu (right mouse button) and click End Process Tree. Restart your computer again.
3. Didn't it help? Now the surgical method. Open Windows Explorer. Find the Windows folder. Select the C: \ WINDOWS \ Prefetch folder. Delete this folder. Then open the Task Manager again and close the tree of the overloaded svchost.exe process again. Restart the computer.

Basically, if in fact the problem was an accidental failure of the svchost.exe process, everything should be fine. If problems persist, the cause must be looked for elsewhere. It is possible that a viral infection actually occurred. Then you need to take a closer look at all the processes and try to identify the masked virus.

Symptoms of a virus under the mask of the svchost.exe process

The normal svchost.exe processes run under the username:
- SYSTEM LOCAL SERVICE
- NETWORK SERVICE

Or something like that. Viruses hide under the username ADMIN or somehow logged into a Windows user account.

If a mishandled Cossack is found, complete its tree and thoroughly clean the system with an antivirus. Don't be afraid if you accidentally disable the normal svchost.exe process. The smart Windows system will simply reboot automatically.

Be sure to install a decent antivirus suite if you use the internet. Especially if you like to explore new sites, experiment with programs and other entertainment with an eighteen plus sign. Download the Dr. Web CureIt. Copy to a USB stick and store for a rainy day. This program does not require installation and is capable of finding and neutralizing viruses on already infected systems.

For the darkest day, save up the Windows distribution and make backups of important documents in a timely manner.

So, today we have to deal with a very interesting computer process. It is called Svchost.exe netsvcs. It is this point that causes concern and alarm among many users. After all, over time, it begins to load the operating system. Sometimes at once by 50 or 100%. And, as a rule, it becomes simply impossible to work. Today we will learn what Svchost.exe netsvcs is, and what to do if this process takes a lot of system resources from the computer. Mainly - memory. Let's get down to exploring today's issue.

Description

But first, you need to understand what it is all about. Initially, all computer processes are not dangerous. But only for the time being. They perform specific functions. These safe processes include Svchost.exe netsvcs.

Initially, this is the name of the processor hosts that are dynamically started using the link libraries. In other words, this item is responsible for the computer libraries. More precisely, for their launch and performance. Of course, the more libraries there are, the more resources are needed. But there is a limit to everything. So, over time, many users begin to notice that Svchost.exe netsvcs is running out of memory. Windows 7 is an unrivaled leader in this regard. What to do in this situation?

Reboot

The first scenario is a banal computer restart. It is very important if you have not turned off the operating system for a long time. In this case, your memory will be filled not only with Svchost.exe netsvcs, but also with other functions that are important for work. Also, maybe you just had a minor system crash. It does not pose a threat to data, but a weighty imprint is imposed on the performance of the computer and its memory.

It is in this situation that the most common reboot will help. The system will restart completely and you should be able to work normally. So many users are struggling with the problem. But it helps only in the listed cases. If the problem that Svchost.exe netsvcs loads Windows 7 memory lies in another, then the approach to eliminate the "hotbed" needs a different one. Which one?

Deleting

For example, you can simply restart the process. More precisely, remove it from the task manager, and then it will start again. This technique helps when the usual reboot or turned out to be useless. The reasons can be different - from a system failure to incorrectly installed content. But the fact remains - Svchost.exe netsvcs needs to be removed from the list of performed tasks.

Press Ctrl + Alt + Del on your keyboard. Now open the Task Manager and then go to the Processes tab. Then find the line you want. Ready? Then select it (left-clicking on the line), then select the "Finish" command. You will be given a message about the irreversibility of the process. Agree with him, and then confirm your actions. Our process will disappear for a while, and then it will start. If this did not happen for some reason, then it is worth restarting your computer. With the advent of the process, it will be noticeable how everything fell into place. Now the computer memory will not be fully loaded. But there are other cases as well. They are not eliminated as easily as we would like.

Registry

For example, if you often notice that Svchost.exe netsvcs overloads the processor and memory, then you should consult your computer's registry. Often, problems with this moment arise among users who do not monitor their operating system. For example, they do not clear the system registry. In this case, you can be glad that only one process fails. But everyone can fix the situation. And there is no need to experience special torment here.

Download yourself and install an app called CCleaner. Run it, and then configure - in the scan, mark all partitions of the hard drive, browsers, as well as the registry of the computer. Now, on the right side of the window, click on "Analysis", then on "Cleanup". Wait a few seconds - the computer registry will be cleared. As a result, the Svchost.exe netsvcs process will no longer load the system. In addition, you will have free space on your hard drive. True, cases where our process brings a lot of trouble due to the computer registry are quite rare. Often you have to fix the problem in other ways.

Updates

For example, sometimes you have to refuse to update your computer. Svchost.exe netsvcs memory and processor often overflows due to loading add-ons. They must be discarded. The surest way not to run into unnecessary trouble is to disable downloading and checking for updates even when installing Windows. If you haven't done this, then it's time to think about this task.

For example, visit "Center right in the computer tray. Now go to the settings. You will see a window in which the update options will be available. It would be best to select" Do not check automatically. "This item is marked with a label" Not recommended. "But in our case it is he who can help.

After confirming the actions, restart your computer and disable the Svchost.exe netsvcs process. Now you can check if everything is good with the memory and processor. Yes? Then update the operating system only in cases No? It is worth looking for other ways to deal with the problem.

Rollback

Sometimes it can help True, this option is relevant when the process loads your computer for a short time. In order to perform this action, go to "Start" and select "All Programs" there. Find "Special" and then "Service". In this list, you will have to find "System Restore".

Read the information in the window that appears. For example, you will have to take into account that a given AND cannot be interrupted. Agree with the information and then choose what is called a rollback point. By default, they are automatically generated from time to time. Click "Next" and then wait for the process to finish. During this period, the computer will automatically reboot several times. Do not be alarmed, it should be so.

The rollback will complete after approximately 30 minutes. And you will no longer load the processor and memory of Svchost.exe. It is worth agreeing to this action only if you are fully confident that the system as a whole is working normally. Otherwise, your rollback may be critical for your computer.

Viruses

True, problems with processes are often the result of infection of the operating system with various viruses. In this case, you will have to permanently cure the computer. This is the only way to improve the performance of the system. Please note that under Svchost.exe a computer infection is very often encrypted. It runs as a user, not System.

You will need to scan your computer with an antivirus and cure everything. If you cannot treat it, delete it. Now clean your computer's registry (CCleaner will help you with this) and reboot. That's all the problems are solved. Only now a complete reinstallation of the computer is often needed. Only in this case can we hope to eliminate all problems.

At one's own risk

However, if the real problem is Svchost.exe netsvcs (Windows 7 most often has problems with it), but you are not very happy with the prospect of reinstalling the system, you can try to act at your own risk. You will need to delete the folder called Prefetch. It is located in Windows.

Next, visit the Tasks folder. All documents should be cleared in it. Next, get rid of Svchost.exe. You can restart your computer and see the result. This is a very risky business. And often you still need to reinstall Windows after that. So it's best not to try to deal with the problem in this way.
