catroot2
About this tag
The catroot2 folder is a critical Windows component used by the Cryptographic Services to store signatures and certificates during Windows Update. When this folder becomes corrupted, it can cause update errors such as 0x80070002, 0x800f081f, 0x8024a105, 0x80073712, 0x800f0905, and 0x80073713. Troubleshooting often involves stopping the Cryptographic Services and Windows Update services, renaming or deleting the catroot2 folder, and then restarting services to force Windows to rebuild the folder. This process is a standard step in resolving stuck or failed updates on Windows 10 and Windows 11. The catroot2 folder is distinct from the SoftwareDistribution folder, which handles update downloads.
