I just want to change a running task's priority to realtime, but the taskmanager won't let me do it. If I try it, it'll just tell me that it can't change to realtime and then changes it to high instead.

I created a link to the task manager. Ran the link as administrator. And still no luck.

Any ideas?

Why would you need something real-time? It's not exactly something common. – alex Nov 5 '09 at 16:55
There's an application I want to leave running, but it slows down terribly whenever it's unfocused. Not sure if setting it to real time is gonna make a difference, but I thought I'd give it a try. (and I will, shortly) – Malabarba Nov 5 '09 at 17:33
Set it to high priority is good enough. – deddebme Nov 5 '09 at 17:44
Yeah, I just tested it and setting it to realtime didn't do any good that high could do, the issue must be within the application. Worth a try anyway. – Malabarba Nov 5 '09 at 17:52

Try Process Explorer from Sysinternals. Make sure to run it as Administrator. Also what process are you trying to change? Certain services don't allow this for stability reasons.

Seems to have worked. I think the shorcut I created just wasn't really running as admin. Thanks – Malabarba Nov 5 '09 at 17:31
