Unable to Change Priority in Task Manager

Generally speaking, owning a low-spec PC or laptop may result in sub-par performance for many intensive games. If the game has high requirements, you may experience issues like low frame rates and crashes.

Changing the process priority of a game or program to high in Task Manager is one way to resolve this issue. This notifies Windows that the process should get more resources.

However, sometimes you may not be able to change the priority in Task Manager. Either an access denied warning will appear, or the priority will not change at all. This can happen to a single process on all platforms or to all processes on the system.
