This negatively affects productivity... Increasing the database system registry promotes dynamics of work with a computer in terms of experiments with third-party software. When installing the program, they register their keys in the registry, which are stored there even after these programs are removed from the system. Invalid keys of remote software over time accumulate and litter such an important Windows work area.
The way out of the situation is periodic cleaning... But it is important to understand that this kind of optimizing operation will not solve the problem globally. low-power computers, in particular, with slow HDDs on board.

Conversely, overwriting data during defragmentation will reduce the SSD resource.

- Useful programs for Windows 10
The Windows registry is a hierarchical system database that contains all settings, presets, changes and other information vital for the operation of all software and Windows itself. It is very difficult to overestimate the importance of correct organization, since the entire performance of the system depends on its content, and any mistake made in it can have completely unpredictable consequences. And while Windows 10 has been able to dramatically reduce the number of errors in the registry, the remaining ones can still cause problems of various sizes. Next, let's figure out how often cleaning is required and how to properly carry it out.
Registry errors and reasons for fixing them
To begin with, it is worth clarifying that cleaning the registry means correcting its errors.
If you want to clean up some hard disk space by getting rid of system junk(sometimes inexperienced users take this for cleaning the registry), enter "% temp%" in the search, open the found folder and delete all its contents.
90% of system junk is located here
As already mentioned, the registry is an operating system database that accumulates all settings and presets. It is constantly being rewritten and changed: with any changes in the system parameters, the installation of new applications, each update and even the start of the computer. In other words, active interaction with the registry occurs very often and any system failure, a sudden power cut or even a bug third party application are capable of causing a registry error if it happens at the wrong time.
The consequences of this can be absolutely any and each time unique: one of the applications refuses to start, the computer will no longer see drive D, the main Windows language will change to Arabic and, of course, " Blue screen of death". The cause of any problem on your computer, if it appears after starting Windows boot, there may be a registry error.
Many critical errors are treated with a simple rollback to last point recovery, but the main problem is that registry problems are rarely noticed in time and it is completely incomprehensible where to roll back.
If we classify all errors very roughly, we can distinguish the following variants of their consequences:
- The registry error is so minor that it does not and will never cause absolutely any problem for your computer.
- Some kind of insignificant change that you happen to notice only at the most inopportune moment, for example, complete rejection in deleting something.
- An error invisible to the user, but very unpleasant for the system. A registry error can cause poor performance on your computer.
- A time bomb that will manifest itself long after the error occurs.
- The error triggers a chain reaction and problems are moved outside the registry. This option is the saddest, since a simple registry cure will not help here and all that remains is to reinstall Windows.
Based on all of the above, fixing registry errors is not so much the elimination of the problems that have arisen, but rather a preventive procedure, which is recommended to be done about once every three months, even if the computer does not have any noticeable problems.
It should be borne in mind that correcting registry errors may not always be correct, and the very concept of a registry error determines the program or utility with which you are treating.
Correcting registry errors can cause them to be created, which happens very rarely, so it is recommended to make backups before each treatment.
How to clean the registry using standard Windows 10 tools
Unfortunately, the standard Windows tools 10 do not have at their disposal to cure the registry or the ability to check it for errors. For these actions you will need to download an alternative software as described in the next chapter.
All actions described in this chapter will be carried out through the registry editor, which can be accessed by entering "regedit" in the search through the "Start" menu or in the "Run" utility.
If you have problems with entering the registry, see how to fix it at the end of the chapter.
Change settings
It is worth clarifying right away that manual change registry settings, you will not fix the errors that have arisen in it. It is theoretically possible, but it is a titanic work and in a similar way not even the most experienced users.
This section of the article is intended for users who already know what they want to change and the path to necessary setting but are not familiar with the registry editor.
Changing the registry settings is used to make any targeted changes to the standard Windows services... There is no intuitive interface here and with one simple glance it is impossible to understand what is responsible for what. Therefore, it is not worth going into the registry editor for no reason, without first having found out on the Internet the path to the setting you need.
We'll look at how to make changes to the registry using the example of returning the Downloads folder to the This PC section, which was previously deleted from there using the same registry editor.
We need to return one of the missing folders All we need to know: the path to the required setting (HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ FolderDescriptions \ 7d83ee9b-2244-4e70-b1f5-5393042af1e4 \ PropertyBag), the name of the parameter (ThisPCPolicy (Show) and the decryption of its values show, Hide - hide).
- First you need to get acquainted with the interface. On the left side of the window, you select the path to the required setting. By clicking on the check mark next to required folder, you will open its nested folders. By clicking on the folder itself, you will see the parameters written inside, which will be displayed on the right side of the window.
First, you should get acquainted with the interface. - Let's go along the path we need. The last folder does not need to be expanded, click on it to display the parameters.
The last folder does not need to be expanded, click on it to display the parameters - On the right side of the window, open the parameter you are looking for. If it is not there, press right click mouse on free space and create the required string parameter yourself.
On the right side of the window, open the parameter you are looking for - Introduce desired value and confirm the change.
Enter the desired value and confirm the change - The Downloads folder is back in place.
The Downloads folder is back in place
Create a restore point and rollback
At the very beginning of this article, we mentioned the registry restore points to which you can roll back in order to restore the system's health. Unfortunately, Windows 10 does not create backups on its own and you need to do them yourself.
A restore point, a return point, a backup, and a backup are one and the same when it comes to the registry.
It is recommended to create restore points after Windows installations and drivers, but only after a couple of computer reboots, when everything is set up and works great; as well as before fixing registry errors and installing questionable programs.
What to do if access to the registry or some of its sections is denied
By default, access to some registry keys is closed even for computer administrators, and only the system itself has the right to change them. In limited versions of Windows or after some kind of trouble (for example - viruses), even access to the registry editor itself may be closed. Fortunately, all of this is very easy to treat.
If you have problems accessing a particular section or changing its parameters, first try the following method:
If previous way did not help you or you have problems entering the registry editor itself, this will definitely help:

But as practice shows, the occurrence of registry errors has not gone anywhere, as well as the need for their treatment with the involvement of third-party programs.
CClaeaner
CCleaner positions itself as a program for cleaning windows from system garbage, but most users are only interested in its function of cleaning the registry, which over the years of its existence has not yet seen worthy competitors.

It is far from the fact that this program is the best, but together with the simplicity of the interface, proven and widespread, it is ideal for most users.
Alternative programs
If CCleaner does not suit you or you want to be on the safe side alternative program, here is a list of the most reliable ones:
