Windows update

When you install a new update, Windows keeps an older version of the operating system. Thanks to this option we can uninstall updates in case the system is not working correctly. Therefore, if you do not plan to uninstall any updates because your OS is working properly, you can proceed to remove the previous version.

Windows Defender

This option is responsible for removing all non-critical files used by Microsoft’s antivirus. Although the company did not explain what kind of files are being deleted, surely they are temporary files and nothing more. It is safe to remove them.

Windows update log

When upgrading Windows from version 7 to 10, from Windows 10 to anniversary version, etc. The operating system is responsible for creating files which can help to identify certain problems that could occur, again if you do not have any kind of problem, it is safe to delete them.

Downloaded program files

You shouldn’t have any kind of problem deleting all the files found in this section.

Temporary internet files

This section contains the browser cache for Explorer and Edge. The cache is responsible for saving certain files from different websites so that they load faster when we visit them again. This is highly recommended to delete it from time to time as well, since if you store too many cache files, you will not only take up a lot of space. If not, some sites may not work correctly.

When the famous blue screen appears, the system creates a memory dump file. This file is able to help us find the origin of the problem to solve it. The problem is that such files can take up a large amount of disk space.

This is something quite important, we already talked about it before. In order for you to reset your computer to factory settings, it is essential to have these files. Unless you are willing to download Windows 10 media again in case of any issues.

Previous Windows installations

When a new version or update of Windows is installed, the system takes care of saving the files of the previous version for 10 days. Then these files will be automatically deleted. In this way, you will get enough storage space. However, from this section you can delete us immediately.

Recycle Bin

I think we all know very well what you mean. It is where all the files that we decide to delete go to, as you know they are not permanently deleted until we empty the trash.

Temporary files

Checking this option will delete all those temporary files that have not undergone modifications for a week.
