Fixing Windows Update Error Code 0x800F081F
Windows Update error 0x800F081F occurs when the update installer cannot find required files in the Windows Component Store or specified source files—often due to corrupted .NET frameworks, missing features, or damaged Windows images. This error halts critical updates, leaving your system potentially insecure or unstable. To resolve it, follow these steps:


  1. Run the Windows Update Troubleshooter: Navigate to Settings → Update & Security → Troubleshoot → Additional troubleshooters, and execute the tool to detect and fix common issues automatically.

  2. Check .NET Framework Features: Open Control Panel → Programs → Turn Windows features on or off, ensure required .NET Framework versions (e.g., 3.5 or 4.8) are enabled, then click OK and let Windows install any missing components.

  3. Repair System Files and Component Store: Open Command Prompt as administrator and run:
    sfc /scannow  
    
DISM /Online /Cleanup-Image /RestoreHealth

    This repairs corrupted system files and restores the integrity of the Windows image.

  4. Specify an Alternative Update Source: If the update still fails, mount a Windows ISO with the same version, note its drive letter (e.g., D:), and run:
    DISM /Online /Cleanup-Image /RestoreHealth /Source:D:SourcesSxS /LimitAccess

    Replace D: with your mounted drive.

  5. Re-run Windows Update: After completing the steps above, restart your PC and check for updates again.
