im trying to view all machines on Win 10 1903 (18362).
If I set the OS version filter to *18362* it shows all 1903.
If I add a NOT in the front it returns nothing.
I want to see all Win 10 PCs that are not on 1903.
Are you doing this on the OS info section of the view? If so , you need to use the advanced filter section with OS version to use NOT.
I feel so stupid.
I was using the OS version filter on the front page, didnt even bother looking in the advanced filtering.
