The system: Windows Server 2012 R2.
When I try to install KB4284863 it install successfully, but on reboot it says something like "Failure to configure updates. Reverting changes" The exact error might be different, since I have not English Windows.
Tried clean boot. In clean boot I disabled non-Microsoft services, but couldn't find the way to disable startup items. After clean boot the issue persist.
Tried Windows update troubleshooter and issue persist.
Tried deleting %systemroot%\SoftwareDistribution folder and the issue persist.
Tried DISM.exe /Online /Cleanup-image /Restorehealth - The restore operation completed successfully. The component store corruption was repaired, but the issue with update persist.
