Solutions to Fix “Windows Update Components Must Be Repaired”

Below are several tested strategies for fixing the error. Depending on the cause, you may need to try more than one method.

1. Run the Windows Update Troubleshooter

This is often the first step. Windows includes a built-in tool that can detect and fix many common update issues.

1. Click on Start and go to Settings > Update & Security > Troubleshoot.
2. Select Windows Update and click Run the troubleshooter.

This method requires using Command Prompt to stop certain services, rename update folders, and restart services. Here’s how:

1. Search for cmd, right-click Command Prompt, and select Run as administrator.
2. Stop key services using these commands:

   net stop wuauserv
   net stop cryptSvc
   net stop bits
   net stop msiserver
       

3. Rename update cache folders:

   ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
   ren C:\Windows\System32\catroot2 catroot2.old
       

4. Restart the services:

   net start wuauserv
   net start cryptSvc
   net start bits
   net start msiserver
       

Once that’s done, reboot your PC and try Windows Update again.

3. Check and Repair System Files

Corrupt system files may be the underlying issue. Use the System File Checker (SFC) and DISM tools to fix it.

1. Open Command Prompt as administrator.
