Task manager requiring elevation for regular users in Windows 10
Finally I have found the solution to this. Props go to a reddit post.
The issue is with the group policy "load and unload device drivers". Computer configuration -> Policies -> windows settings -> security settings -> local policies -> user rights assignment -> load and unload device drivers.
if this is set to a group the limited user is a member of (everyone, domain users, etc) then the prompt is displayed. if you set it instead to Administrators, the prompt is suppressed and everything works fine. I am not sure the ramifications of changing this value as it has been set for us since time immemorial. Seems to have to do with accepting unsigned device drivers. If everything suddenly stops working then i will have to set it back, but the setting goes all the way back to win2k so it may no longer be relevant (except to F up my shiz)...
