Fix it now
1. 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.
2. 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.
3. 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.
4. Clear the software distribution cache
Stop the Windows Update service, delete the contents of C:\Windows\SoftwareDistribution\Download, then restart the service and try updating again.
5. Install the update manually
Visit the Microsoft Update Catalog, search for the failing KB number, download the matching .msu file and install it manually.
