The following DISM commands must be given in the chronological sequential order of:

First

1.dism /online /cleanup-image /startcomponentcleanup

2. dism /online /cleanup-image /restorehealth
1. Restart
4. sfc /scannow
1. Restart
Second:

("Resets" Windows Update)
1. Create bat and run as ADMIN:
net stop wuauserv

rmdir /s /q C:\Windows\SoftwareDistribution\DataStore

rmdir /s /q C:\Windows\SoftwareDistribution\Download

net start wuauserv

pause
