Hi,
C:\Windows\system32\CatRoot2 folder is an impotant folder which helps to fetch regular Windows Updates. The Catroot2 folder is automatically recreated by Windows once it is deleted. For the most of the windows Updates issues, once you delete or rename the catrrot2 folder wil fix the issue because once you have renamed or deleted the catrroot2 folder it will refresh the update history..
Hi,
Just An Added Information To What You Have Mentioned. Its A Folder Which Stores The Signatures Of Windows Update Package And Allows It To Be Installed. The File %windir%\System32\catroot2\edb.log will be updated by the cryptographic services. So Inorder To Delete The Folder The Cryptographic Services Has To Be Stopped First. All The Updates Are Stored Under The Folder %windir%\SoftwareDistribution And Its managed By The Automatic Updates Service.
