one day morning I started my laptop and windows 7 started patching windows 7 with updates.
after some seconds it started giving below screen with message
Failure configuring Windows updates. Reverting changes…
it was taking lot of time like in loop , so tried to restart in safe mode but no success .
change network point and restarted and problem solved.
Method 2 ( if network is connected properly )
- start system / laptop in safe mode
- Download Windows Update Trubleshooter from https://support.microsoft.com/en-ie/help/4027322/windows-update-troubleshooter
- execute the downloaded windows update trubleshooter and select windows update
click next …finish
need to reboot to resolve the issue.
