Question
What do I do when it tells me I am not an admin when I'm trying to change priorities?
Nikita Manahov
Community Answer
That means that you are not logged in as the "Administrator" user, and/or don't have Administrator permissions. To change process priorities, you must have Administrator permissions.

Warnings

"Realtime" means this process has exclusive rights to the system resources above all else, including normal window processes. This means that of all the priority options, "Realtime" is the most likely to make your computer crash.

On slower computers and with some high memory usage programs, changing process priorities may crash your computer.
