Windows 10 Broken

[ITGURU]

I have 200 PCs on windows 10 all were fine.

 

Deployed the latest upates during the holidays.now getting reports of volume slider not coming up , calendar doesnt come up, cannot even open local settings on admin or built in local admin.

 

 

ran dism check health, restore health - all ok

sfc returns no problems.

 

 

uninstalled the recent updates using the classic type control panel uninstall updates as cannot get into settings, updates.

 

 

any ideas ?

 

i'm at a lost cause with 200 broken machines but seems to be related to the shell host experience from what i can tell.

 

 

if i manually run the exe it briefly pops up in task manager then disappears, and windows problem reporting appears then disappears.

on the folder it has the modified date that the updates were installed, but uninstalling the update doesnt bring back the functionality.
