I am running windows XP on an HP Pavilion Notebook model zx5160us with 2 GB of RAM and a Radeon Mobility 9200 Video Card and a Pentium 4 Processor. When tying to change the priority for Warcraft III's process, war3.exe, I get an "access denied" message. This has happened when I attempted to do it through Task Manager and the Command prompt. How do I change the priority, with this restriction on it?
