Windows users often ask us what is going on in the two Windows system folders
saved and how can the content be deleted if necessary.
The ” Catroot ” and ” Catroot2 ” folders are Windows internal system folders that are absolutely necessary for the Windows update process. Windows Update files are saved in these folders as in the ” SoftwareDistribution ” folder , whereby the CatRoot folders are used more for storing the Window Update signatures .
If there are problems with Windows update processes , it may be necessary to delete the contents of these Catroot folders . We have already reported several times about deleting the SoftwareDistribution folder. As soon as Windows downloads the missing Windows Update files, the contents of the ” Catroot ” and the ” Catroot2 ” folder are automatically rebuilt.
Here is a sample content of the Catroot2 folder for a Windows 10 installation.
You cannot easily delete the contents of these Catroot folders, since parts of these files are permanently accessible through Windows.
Delete Catroot folder
To delete the contents of the Catroot folder , you must first stop the Windows service responsible. This is the
Cryptographic service (cryptsvc)
and the easiest way to end this is via the command prompt (with administrative rights) using the following command.
net stop cryptsvc
Then you can delete the contents of the folders. However, we would advise you to make a backup copy of the two folders beforehand .
Then you only have to restart the cryptographic service “cryptsvc” using the following command.
net start cryptsvc
By the way, Microsoft has released the following information about this service and thus also about the Catroot folders.
Provides three administration services: the catalog database service, which confirms Windows file signatures and enables new programs to be installed; the protected root service, which adds trusted certificates from root certification authorities to this computer and removes them from the computer; and the automatic update service for root certification , which retrieves root certificates from Windows Update and enables scenarios such as SSL. If this service is stopped, these administrative services will not work properly. If this service is deactivated, all services that are expressly dependent on this service cannot be started.
After deleting the folder contents of the Catroot folder, you should restart Windows Update and check whether your Windows Update problems have been eliminated,
