Fix it now
1. Run SFC and DISM scans
Open Command Prompt as administrator and run sfc /scannow. If issues are found, follow up with DISM /Online /Cleanup-Image /RestoreHealth. Restart your PC afterwards.
2. Run the Windows Update troubleshooter
Open Settings > System > Troubleshoot > Other troubleshooters and run the Windows Update troubleshooter. It automatically detects and repairs the most common update problems.
3. Temporarily disable firewall or antivirus
Some security suites block update servers. Briefly disable third-party antivirus and Windows Defender Firewall, retry the update, then re-enable them right away.
4. Free up disk space
Windows updates need room to install. Use Storage Sense or Disk Cleanup to free several gigabytes on the system drive, then retry.
5. Check your system date and time
A wrong system clock breaks secure connections and can trigger update errors. Set time and time zone to automatic in Settings > Time & Language, then sync.
