Finally figured out what was happening…
It was AMD’s ReLive DVR/Desktop Overlay. I have an AMD GPU but I don’t have AMD ReLive installed, nor do I use it but it seems that these two files remain active indefinitely.
I used an app called HotKeysList and closed processes one by one from Task Manager until I saw that the Hot Key was gone.
The only fix I have found so far is to navigate to this location (C:\Program Files\AMD\CNext\CNext) and then rename these four files: ‘amddvr.exe’, ‘amddvr.reg’, ‘amddvr64.exe’, and ‘amdow.exe’.
This fixed my issue with the login hotkey. Hope this helps someone!
