net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old

After executing these commands, restart your computer and attempt to install updates again.

Perform a System File Check (SFC) Scan

An SFC scan can identify and repair corrupted system files that may be contributing to the error. Open Command Prompt as administrator and execute the command: sfc /scannow.

Download and Install Updates Manually
