Windows Update Error C80003FE generally appears when your system fails to complete an update due to corrupted files, network disruptions, or interference from antivirus software. This error may occur across multiple Windows versions and often prevents your system from downloading or installing updates correctly.
To begin resolving the issue, temporarily disable your antivirus and firewall, as they can block the update process. Then, open Command Prompt as administrator and run sfc /scannow followed by DISM /Online /Cleanup-Image /RestoreHealth to repair system file corruption and restore update functionality.
Next, reset the Windows Update components by stopping services like Windows Update, BITS, and Cryptographic Services. Rename the SoftwareDistribution and catroot2 folders in the Windows directory, then restart the services. This clears old cached data that may be interfering with current updates.
You should also run the built-in Windows Update Troubleshooter, available under Settings → Update & Security → Troubleshoot, which can automatically detect and resolve many common issues related to updates. If the error persists, download the problematic update manually from the Microsoft Update Catalog and install it offline.
