If windows updates fail to install;
First of all make sure your Time is set correct on your Computer ( you will
find in the Right-bottom of the screen).
Open a run command and try to Re-register these DLLs for the update Engine:
net stop wuauserv click [OK]
regsvr32 wuapi.dll click [OK]
regsvr32 wuweb.dll click [OK]
regsvr32 atl.dll click [OK]
regsvr32 wups2.dll click [OK]
regsvr32 wuaueng1.dll click [OK]
regsvr32 wups.dll click [OK]
regsvr32 MSXML3.dll click [OK]
regsvr32 wucltui.dll click [OK]
regsvr32 wuaueng.dll click [OK]
net start wuauserv click [OK]
Also Turn any firewall and Defender off for the Update (please turn ON after
the
update either success or failure) Then Reboot your machine and try the
Updates.
You receive an access violation error and the system may appear to become
unresponsive when you try to install an update from Windows Update or from
Microsoft Update
