How to Fix It
1
Clear the Windows Update cache: Open Command Prompt as Administrator, run net stop wuauserv, then delete all contents of C:\Windows\SoftwareDistribution\Download, then run net start wuauserv. Retry the update.
2
Run a disk check: Open Command Prompt as Administrator and run: chkdsk C: /f /r — you will be prompted to schedule it for the next restart. Restart and let it complete (this can take 1-4 hours depending on disk size).
3
Run sfc /scannow to check for corrupted system files.
4
Test your RAM: Open Windows Memory Diagnostic (mdsched.exe), choose 'Restart now and check for problems'. The test runs during reboot and results appear after login via Event Viewer > Windows Logs > System (source: MemoryDiagnostics-Results).
5
Check disk health using CrystalDiskInfo or the manufacturer's diagnostic tool. Look for reallocated sectors, pending sectors, or SMART warnings indicating drive failure.
6
If the error occurs during a fresh Windows installation, re-download the ISO and recreate the installation media — the original download may have been corrupted.
