Hello Robert. Can you confirm if UAC might have been turned off on this machine, either in Control Panel > User Accounts > Change User Account Control settings or in the registry?
A few steps worth trying:
- Check UAC settings, make sure the slider isn’t set to Never notify. If it is, move it up and restart. This restores Windows’ ability to tell elevated from standard processes.
- Open
regeditand go to:
Look for EnableLUA. If it’s set toHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System0, change it to1and reboot. This re-enables UAC at the system level.
You can also try to create a new local user and log in. If Task Manager looks normal there, it means the issue is tied to your main profile rather than the whole system. Curious about this, to see how the system is treating other users in this context.
