I have the same problem as Blake. “When I right-clicked on one of the processes in the Processes tab, a box pops up saying “The operation could not be completed. Access is denied.”” I hope you give me by mailing me an answer. Thank you!

Hi, I wanted to ask how to dedicate a cpu completely to a single process. I mean: when I set an affinity all the others processes will still use a second cpu? Is it possible? Maybe I’m wrong and I simply do not understand.

Thank you
Bye

How do you set permanently the affinity in windows XP to an app. If I set the affinity just like you do, when I close the app the configuration is lost. Is any way to do the change permanently?

In Vista I can use the parameter affinity in the start command but in XP I can’t. Thanks!

How do you know if a program supports multi-threading or not? Can I set affinity the same way in Windows 7? And if I have a Quad core machine, how many CPUs will I see?

HI, you just now mentioned that older applications (mostly) don’t support hyper-threading, but again below that you suggest I can set affinity of such applications restricted to one core…. how???? i am confused. one more thing….

Should i restrict an application to a physical processor or to a virtual one, or either will work? pls if u can then reply via mail…..thanx a lot. I went thrugh all your posts related to task manager. great work.
