How to fix the "Windows Update couldn't complete the updates, undoing changes" error

 Are you a Windows user who has encountered the frustrating error message, "Windows Update couldn't complete the updates, undoing changes"? If so, you're not alone. Many Windows users have experienced this error, which occurs when Windows is unable to install the latest updates and reverts back to the previous state. In this article, we'll discuss some of the most effective solutions to this error.

Solution 1: Restart Your PC

One of the simplest solutions to this error is to restart your PC. Sometimes, a simple restart can resolve issues with Windows updates. To do this, go to the Start menu, click on the Power icon, and select "Restart." After your PC restarts, try to install the updates again.

Solution 2: Disable Antivirus Software

If restarting your PC doesn't resolve the issue, the next step is to disable any antivirus software you have installed. Antivirus software can sometimes interfere with Windows updates, so disabling it temporarily can help. To do this, open your antivirus software and look for an option to disable it temporarily. Once you've disabled your antivirus software, try to install the updates again.

Solution 3: Use the Windows Update Troubleshooter

Windows has a built-in tool called the Windows Update Troubleshooter that can help fix issues with Windows updates. To use this tool, go to the Start menu and search for "troubleshoot." Select "Troubleshoot settings" and then select "Windows Update" under "Get up and running." Follow the prompts to run the troubleshooter and see if it can resolve the error.

Solution 4: Clear the Windows Update Cache

Another solution is to clear the Windows Update cache. This cache stores the files that Windows uses to install updates, and sometimes it can become corrupted. To clear the cache, follow these steps:

1. Go to the Start menu and search for "cmd."
2. Right-click on "Command Prompt" and select "Run as administrator."
3. Type "net stop wuauserv" and press Enter.
4. Type "net stop cryptSvc" and press Enter.
5. Type "net stop bits" and press Enter.
6. Type "net stop msiserver" and press Enter.
7. Type "ren C:\Windows\SoftwareDistribution SoftwareDistribution.old" and press Enter.
8. Type "ren C:\Windows\System32\catroot2 catroot2.old" and press Enter.

10. Type "net start cryptSvc" and press Enter.
11. Type "net start bits" and press Enter.
12. Type "net start msiserver" and press Enter.
13. Close the Command Prompt window and try to install the updates again.
