failure when trying to set windows update schedule.

Hi all. 
Apologies if i have not selected the correct support board.

I have 4 zoom room pc's that seem to be ignoring the OS update schedule. 

Under update management, when i check the OS update schedule i can see that the scheduled install day is set to everyday, and the active hours are from 5am to 11pm with a weekly system restart on Saturday. 

Now over the past 2 week or so the windows update window has popped up automatically over the zoom window and obviously can't be closed without IT interaction as there is no mouse plugged into the zoom room pcs. 

Currently the 4 windows 11 pcs are running zoom room app 6.3.5 (5226). 

Is there a reason as to why this is occurring?

Cheers
