Failure configuring updates. Reverting changes. Do not turn off your computer
If you are facing this issue, your computer will normally take 20-30 minutes to revert the changes. Here are a few steps you may want to try and see if it helps resolve your problem.
1] First, you should try and restart your Windows computer and then try to install Windows Updates again. See if this helps.
2] If it does not, then run the Windows Update Troubleshooter. Although Windows includes a built-in troubleshooter, download one from there as it includes more fixes.
3] Perform a System Restore operation and then try again.
4] Boot into Safe Mode, Run msconfig.exe, select the Services tab, select Hide all Microsoft services and Disable all and Exit. Now restart your computer and run Windows Update.
5] Start your computer in Clean Boot State and see if you can now install the Windows Updates. Installing Windows updates in a clean boot state prevents them being blocked by some Windows Services and software – including security software.
6] Navigate to C:\Windows\WinSxS\ folder, search for a pending.xml file and rename it. You may even delete it. This will allow Windows Update to delete pending tasks and build a fresh new update check. See if this helps.
7] Navigate to C:\Windows\SoftwareDistribution\Download folder and delete the contents of Software Distribution folder. Restart your computer and try now.
8] Run System File Checker.
9] Use the Deployment Imaging and Servicing Management (DISM) tool.
Run DISM.exe /Online /Cleanup-image /Scanhealth first.
Then run DISM.exe /Online /Cleanup-image /Restorehealth to repair your Windows Image.
Once the scan is completed, restart and try again.
10] View your Windows Update History and remove any recent update which may have potentially caused this issue.
Open Settings > Windows Update > View update history.
11] Repair your Windows installation. Some of you may want to consider a Refresh or Reset operation. OEM users may want to consider a factory reset.
Stuck in a reboot loop
