Sometimes Microsoft OS users encounter a problem when after loading Windows only black screen and cursor mice. The symptom is quite well-known - the system process “explorer.exe” cannot start. There can be several reasons: a virus or vice versa - an antivirus (Avast), problems with a hard drive, etc. Quite often fix black screen on startup can be done in a minute without any third-party utilities.
As already mentioned in the title - the reason for this behavior is process start error, which is responsible, among other things, for displaying the desktop, its elements and the panel with the Start button. In this recovery guide, we will look at two popular reasons why black screen and cursor appear when loading windows instead of desktop. One of the reasons in some cases is the popular Avast antivirus, which, for reasons known only to him, blocks " explorer.exe". In the second case, you will have to slightly edit the system registry. In both situations Windows is restored very easy.
Avast is the culprit behind the black screen when loading Windows.
So, after Windows booted up, but on the screen there is only a black "Malevich's square", on which the "abstract cockroach" runs - the mouse cursor, do the following:
- 1. Press the world-famous combination of buttons " Ctrl+Alt+Del” and select “Start Task Manager” from the list.
- 2. After the task manager window appears, find in the list of processes " avast” (Processes tab) and from the context menu (right-click on the process) select “Open file location”.
- 3. Before you appeared a window with a folder where the Avast antivirus is installed. Find the "AvastUI" file in it and run it (double click or "Enter"). The main antivirus window should open.
- 4. Go to the top tab " Security”, in the list on the left, select “ Antivirus", and among the menu items that appear, click on" Behavior Screen».
- 5. Open screen settings and add to reliable processes « c:\windows\explorer.exe" (use the "Browse" button). We confirm our actions with the "OK" button.
- 6. Restart your computer: again click " Ctrl+Alt+Del” and find the corresponding icon on the screen that appears.
If Avast antivirus was the culprit, then after performing the steps from the instructions for solving the problem black screen and mouse cursor on Windows startup– the next boot of the operating system should be successful. It is quite possible that the problem has already been solved by the Avast developers, but the process of adding a program to the “trusted” ones can still come in handy. Moreover, it is not known how the antivirus will react to the upcoming release. Windows 10.
In the event that you are using another antivirus, then try to find in its settings a similar item for creating a list of "trusted", "reliable", "ignored", etc. applications that should not be checked by this antivirus. If the antivirus is to blame, then black screen with cursor on boot You shouldn't be worried anymore. Defender, which reacts so inadequately to popular programs, will most likely receive an appropriate update in the next few days (or maybe hours). It is quite possible that it will be received automatically if you have an Internet connection and a configured function to update the antivirus via the Internet. Otherwise, it is recommended to download the updated version from the official website.
Not always errors and similar situations at Windows startup caused by antivirus. There may also be hardware problems. The review was published recently. But further we will consider the solution when in the current situation ( only mouse cursor on screen) incorrect Windows system registry settings are to blame.
What should I do if I see only a black screen and a mouse when I start Windows? We edit the system registry.
The first step is exactly the same as in the case of an antivirus: you need to open , use it to run registry editor and check/fix a couple of Windows system registry values.
- 1. able black screen press the world-famous combination of buttons "Ctrl + Alt + Del" and select "Start Task Manager" in the list.
- 2. After the Task Manager window appears, in the top menu "File" select "New Task (Run) ...". The Create New Task window will appear. In the "Open" field, enter the command "" (without quotes). The Registry Editor window will open.
- 3. In left side window, navigate to a section (something like "folders" in explorer) called " HKEY_LOCAL_MACHINE". Expand it and navigate to the " SOFTWARE". Similarly, get to the section " HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon».
- 4. In the right part of the window you will see a list of options. Look for a setting called " Shell". Its meaning should be the string "explorer.exe". If this is not the case, then after double-clicking on it, set the specified value. In the event that the "Shell" parameter is absent at all, then create it, selecting from the context menu of the "Logon" section the item "Create" - "String parameter". Specify the name of the new parameter ("Shell") and then double-click to set the value ("explorer.exe").
- 5. As in paragraph 3, go to the section " HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon". Here is the right side should not contain the "Shell" parameter. If there is one, then delete it through the context menu or the "Delete" button on the keyboard.
The two methods above will help you restore Windows if, when you boot black screen and mouse cursor. Changing the "Shell" setting often indicates that the computer has been infected with a virus. It is quite possible that it has already been neutralized by the installed antivirus, but traces of its activity could well remain in the system (Change "Shell").
One of the most unpleasant and, I must say, completely non-standard is the situation when, for no reason, a black screen appears during an update or after an update of Windows 10. The reasons for this phenomenon are not clear to many. And users in a panic start looking for a solution. But do not despair. Even if you are experiencing a black screen after updating Windows 10, there is a solution. By the way, it is also suitable for those who updated the installed eighth version to the "tens". Let's make a reservation right away: it is not so simple, so please be patient.
Why is there a black screen after updating Windows 10?
In general, this situation is rather non-standard, since there are completely different cases. For example, a black screen (with or without a cursor) may occur when upgrading from Windows 7, 8, or a subsequent upgrade from 8.1 to version 10. It can also be observed in already running Windows 10 during or after its own updates.
Let's look at a few reasons that may affect this. As a rule, there are several of them:
- mismatch of previously installed video card drivers;
- crashes in the Explorer service;
- fast start enabled;
- re-licensing.
In addition, it is worth noting separately two more varieties. Firstly, after upgrading to Windows 10, the black screen disappears after a while, and the system returns to normal. Secondly, the black screen "hangs" all the time, but the controls (at least the keyboard) work. In principle, the solutions for almost all situations are, in general, the same. But we will consider them based on the root causes (we are not talking about mechanical malfunctions of computer systems now).
Restoring the system in the standard way
So, after upgrading to Windows 10 - a black screen and no reaction to booting the newly installed system. What to do? Naturally, the easiest solution can be to restore the system to the original "OS" if you have an installation disk or a bootable flash drive.
All this is simple when a disk or flash drive is available. And if they don't, what then? Don't give up. There is a way out: after upgrading to Windows 10, you can remove the black screen with built-in tools, and at the same time return to the old system. This is all the more good because the G8 is not destroyed when upgrading to the tenth version, but is, so to speak, in a deactivated state.
What will need to be done? First of all, we call the "Task Manager" with the standard three-finger combination Ctrl + Alt + Del, and then in it we create a new cmd task (command line launch) with launch as administrator. In the window that appears, write the line shutdown / r / o / f / t 00, followed by a reboot.
Now in the action selection window we use diagnostics, after which we select system recovery in the additional parameters. At the end of the process, the computer will restart again, and then an old working system will appear in front of you.
Windows 10: How to fix "black screen" during update?
The situation described above is not the only one of its kind. In this case, the decision concerned exactly when a black screen appears after upgrading to Windows 10. But what do you want to do if it occurs precisely during the update process? The reason for this, apparently, is outdated graphics accelerator drivers.
If you see a black screen when installing Windows 10, in principle, you can do the simplest way, although it may seem barbaric to many. We perform a forced shutdown and reboot of the terminal or laptop. When restarted, the system will check the hard disk for errors (maybe even in and load the desktop.
To prevent this situation in the future, we update the video card drivers. You can do this from the "Device Manager", but if you have some utility like Driver Booster at hand, even better, because the driver will be downloaded from the manufacturer's official website (and not only for the graphics chip, but also for all other devices that need in driver update) and then automatically integrated into the system. After that, you can try to install Windows 10 again.
Entering Safe Mode
All this concerned the fact that it was after upgrading to Windows 10 that the black screen was the result of system failures or conflicts with drivers. But what if the installation of the "dozens" seems to have been successful? And suddenly the cursor appears before the user's eyes, but the system does not want to start, although the initial boot process clearly indicated that the system is trying to work?
It's not all that simple. If there is an installation disk, there will be no problems. We execute the sequence as shown below (transitions from the diagnostics menu):
Otherwise, secure login mode is required. But with him there are problems. The fact is that the standard pressing of the F8 key when starting Windows in the tenth version does not work (why it had to be removed is still not clear). Nevertheless, not on all devices, but sometimes pressing F8 times like that 10-20 times while holding down the Shift key works.
In the next window, click on the continuation line and, finally, in the boot options window, press the F4 key (safe mode). This is followed by a reboot, the system boots already in safe mode.
How to restore the system in safe mode
In principle, if the "ten" was installed, you can easily return to the old system, however, with one caveat: if the user has not deleted the files of the previous "OS". Otherwise, nothing will work.
You can do this in the security and recovery section, where there is a special link to return to the previous system. Only and everything. The process will end automatically, followed by a restart with the previously installed "seven" or "eight".
If you need to restore the “ten” itself after its own update, you need to type the sfc /scannnow command on the command line (even at the boot stage) and press the enter key (the process of scanning and restoring system files is activated). The process can be quite lengthy, so you have to be patient. You can reboot the system and check its performance using the shutdown -t 0 -r -f command.
But when entering safe mode, you can simply activate the recovery process and select a checkpoint that preceded the appearance of such a situation.
Installing drivers and uninstalling updates
Another step that can be taken by booting into safe mode refers to How to do this, which was described above, so there is no point in dwelling on this in detail.
As for the update packages that could cause such a failure, you should go to the update center and look at the latest installed packages. The latest updates should be uninstalled, then a manual search for updates should be set, and those that caused a critical failure should be excluded from the list. In principle, the automatic update can be disabled altogether. Windows doesn't recommend doing this, but there's nothing wrong with that. Updates mostly concern the security system, office applications, and only occasionally - drivers. But if the user has the same Driver Booster package, the drivers will be updated through it. In addition, the program itself will issue a notification about the need for an update (free version). The Pro version will generally update all drivers in the background. The user will know about it only from the message about successful installation.
Starting the Explorer service manually
Let's consider one more unpleasant situation, when instead of the expected start of the system, we have a black screen and a cursor after loading Windows (in some cases, the cursor may be absent). The reason is a failure in the Explorer service, which was unable to load the Desktop. It will have to be started manually.
We go to the "Task Manager", as described above, after which we find the explorer.exe service in the process tree and terminate the process forcibly. Next, in the file menu, create a new task and enter explorer.exe in the launch line. If nothing happened, you can try to find the file yourself by clicking the browse button. As a rule, the desired file is located in the Windows root directory on the system drive. This may partially solve the problem. As a last resort, we use the same safe mode and scan the system with recovery, as described above.
Enabling Fast Startup
Safe mode is also good because it allows you to change some key parameters that affect the performance of the system. Here we are talking about the so-called quick start mode.
It is turned on from the power section in the standard "Control Panel", where the button action is first selected, and then the inaccessible parameters. We put a "bird" in front of the quick launch line, save the changes and reboot the system.
Getting rid of Windows Activation Technologies
Finally, one of the reasons may be reactivation. If the copy of Windows is licensed, there should be no problems, but sometimes the activation file just causes trouble after upgrading to Windows 10. In this case, the black screen may “hang” all the time.
We use safe mode, in the properties of folders we specify the display of hidden elements, after which we find the folder of the same name. As a rule, for 64-bit systems it is located directly in the directory with the system (C:\Windows), but for systems with 32-bit architecture it can be located in the System32 section, where you need to go first to the Tasks folder, then to Microsoft, and finally - Windows. Delete the folder with all its contents and reboot.
Conclusion
So we examined the main causes of failures after upgrading to Windows 10. A black screen is, of course, an unpleasant thing, but, as we see, it is possible to deal with this type of failure, even if they occur in an already running system. Naturally, some of the above methods will be somewhat difficult for many users to understand or apply in practice, however, if you show a little patience, you can fix the problem yourself, and not run to some service center, and even pay money for it, even small, but still it is material costs.
After upgrading to Windows 10, many users often experience a solid black screen, after which the system stops loading or the process is very slow. This bug first appeared immediately after the release of the assembly and so far it has not been completely eliminated, despite the attempts made by the developer. Many experts and enthusiasts find different solutions to this problem every day. You will learn about some from our article.
- with cursor;
- just a black screen.
A spinning wheel, as shown in the image, may not be at all.
In what cases does it appear?
- Immediately after upgrading a previous system to Windows 10 on its first boot.
- After turning off and then turning on or restarting the computer from a working OS.
What do we have to do?
- First, determine after what your most recent actions a solid black screen began to appear.
- Then, based on the analysis of the first paragraph, draw a conclusion about the possible causes of the bug.
- Restore the system.
Black screen after updating the system to Windows 10: causes and solutions
Software failure
The failure could occur without the user noticing during the upgrade process. To restore the system, just repeat the update process and the black screen will disappear.
Windows 10 upgraded system conflicts with previously installed graphics card drivers
Here it is somewhat more complicated. To get started, you just need to get into the system.
If a solid black screen appears when you boot Windows 10, but then the OS still loads, then take the following steps, after completing each of which, restart your computer:
Update video card drivers If during the boot of Windows 10 you see only a black screen, then you must first log in using safe mode, and only then do everything described above.
Necessary steps to enter safe mode:
The computer restarts and the system boots in safe mode.
You can also enter safe mode using the Windows 10 installation disk, and if it is not available, use the eighth version of the system:
After opening the first window, click the "Next" button.
The first pop-up window after starting the disc 
System Restore
In the future, starting the system in safe mode follows the same sequence as shown above.
Automatic redirection to the second video card slot
Connect the monitor to an available video card slot on the back of the system unit.
If already running Windows 10 crashes: causes and solutions
Device in conflict with the system
Disconnect all newly connected devices to the computer and start Windows 10. The black solid screen does not appear. Connect devices one at a time and restart your computer before failure occurs. After that, disconnect the hardware that conflicts with the system and start the OS in normal mode. Update the drivers on the problem device.
Installing new drivers for the video card
Go back to using the old drivers or restore the system to an earlier state and the rollback to the previous settings will happen automatically. You can select old drivers in the update window in Device Manager. How to get there has already been discussed above.
To start the recovery process, do the following:
You already know how to enter safe mode if the black solid screen does not disappear and Windows 10 does not start at all. Let's go further.
- If the system starts up after a solid black screen after a while, then first reboot in safe mode from a running Windows 10, to do this, while holding down the Shift key, press the “Reboot” drop-down list item from the “On / Off” menu, which can be accessed through the main start menu.
Reboot in safe mode - Select "Diagnostics".
Select from a list - Click "Advanced Options".
Intermediate choice - Select System Restore.
Recovery scheme - Press "Next".
Intermediate choice - Select a restore point and click Next.
restore point - Click the Done button.
Action confirmation - Confirm your decision to restore the system by clicking the "OK" button.
The final stage
After the reboot, the system will be restored to its original state.
Computer virus infection
This could happen while browsing the Internet or installing unverified software. If necessary, boot Windows 10 in safe mode, scan the system with an antivirus program and remove infected files, and then restart your computer.
Screen resolution
The display resolution may not be supported by the video adapter. Restart the system in safe mode, change the screen resolution to a lower one and restart the computer.
After all the troubleshooting, in order to prevent the menu with a choice of boot modes from popping up on subsequent launches of Windows 10, you need to right-click on the Start menu item "Command Prompt (Administrator)" from the drop-down list with a running computer, enter command "bcdedit /deletevalue (globalsettings) advancedoptions" and press the Enter key. Windows 10 will now boot normally.
Video: one way to fix the problem
Getting rid of the black screen in Windows 10 was not so difficult. After performing these steps, the operating system will boot without delays and failures, and the black screen will remain in the past.
After the release of a new operating system from Microsoft, many people immediately rushed to install the top ten on their computers, especially since the manufacturer, this time, prepared a real surprise - the ability to upgrade the previously installed seven or eight for free. Of course, if these were licensed versions. But, some users, immediately after upgrading the system, are faced with a rather unusual problem - a black screen when loading Windows 10.
The unusual thing is that the black screen after upgrading to Windows 10, as it were, does not have its own code, which immediately confuses some people. Before you start fixing the Windows 10 black screen, you should determine the cause of its occurrence.
Why does
According to statistics, in most cases, it occurs due to a conflict with the drivers that are necessary for the operation of an AMD graphics card. The new ten is still quite a crude operating system. Therefore, it is not surprising that this problem occurs after upgrading to Windows 10, but before everything worked fine - the developers have more or less figured out the previous generations of the OS, but the new product still has to work and work.
Do not panic ahead of time if it occurs during boot - there are good chances that the problem can be fixed with fairly simple methods.
Troubleshooting
So, how to fix the situation if, after installing a new OS, the system does not start for a long time, but in the end it occurs when Windows 10 is loaded?
First of all, it is worth noting that the solution of the question posed is simplified by the fact that the user has the opportunity to work with the installed system. This problem usually manifests itself like this:
- After installing Windows 10, it takes a long time to load - a black screen.
- After some time, access to the operating system appears - the start menu and the mouse cursor work, and in front of us is the standard window of the new OS.
Therefore, the first step in our fight against the fact that a black screen occurs when starting Windows 10 is to access the system settings:
- Open the start menu and look for settings.
- Go to the sub-item "System".
Considering that the black screen with the Windows 10 cursor is associated with video card drivers, we naturally look for the right device: - Programs and Features menu.
- Scroll through the list and find the equipment you need.
- Remove all installed drivers.
Since it is only associated with the new version of the AMD driver package, you need to search for the previous version of these files and install them in place of the deleted ones. How to do it correctly so that there are no other conflict situations:
- Usually the entire package is enclosed in an archive, which should be downloaded and unzipped to the desktop in a folder specially created for this.
- Go to the "Device Manager" menu.
- Find hardware that is listed under the name "Microsoft Basic Display".
- Open settings, then update drivers.
- It is advisable to specify the path to the required components yourself. That is, show the system where the installation should be performed from.
- After the process is completed, reboot the operating system.
Why should I not select the "Prepare Automatic Updates" option? The reason is that the OS will start to search on its own and, of course, will look for the most recent version of the drivers. Naturally, she will find similar ones to those that were just removed - and install them again. Where it leads? That's right - to the appearance of the same black screen, which we need to avoid.
