Yesterday evening I was surprised to see the "Run as administrator" was missing from the right-click context menu and everywhere else, including from the app selection in the Search menu in my Standard user and even my Administrator accounts on Window 11, 21H2. I had no idea why and between then and this morning I must have spent a good three hours trying different things such as: breezing over the settings in H_C (this was my fatal mistake, breezing
) sfc /scannow, Easy Context menu application, registry editing suggestion from Google searches, disabling and even uninstalling OSArmor, and checking Group Policy settings. Still no luck. I finally revisited H_C and selected Tools->Restore Windows Defaults
and voila, I got it back! I took another look and discovered 'Hide Run As Administrator'
had been set to "On" before I restored Windows Defaults
I had completely forgotten that setting even exists and of course I missed it the first time I checked, and I've no idea why it was enabled, although I must have absent-mindedly enabled it recently. How embarrassing, but at least I got it back and just avoided my next step which was to restore a recent backup, which would have resolved the issue, but then I wouldn't have known how it happened in the first place
