Currently on 22H2, but it started on 21H1, fresh installed as Vista. So this started a while ago, but nothing major was installed/changed at that time that I can remember. User is admin, UAC off. No policies configured that would affect this (ie explorer's "do not run"). Basically the problem is that al installs require them to be run "as Administrator", even msi (had to do some registry hackery to add that option to right-click menu). Another symptom (started happening at the same time) is that any links clicked in Outlook that would be opened in browser error out with message "This operation has been canceled due to restrictions in effect on this computer". Anyone dealt with similar problem?
