Hey i have an issue with my number of processors. Im kind of a noob at this, but I had a friend change my processor number from one to four. I thought this was making my computer work much harder and making it overheat, but thats because i was on a bed. I found that out after i changed it back to one, and now i cannot change it back to four processors. It only displays one of them. If anybody has a solution to this, i would appreciate it sooo much. Please help. My computer is very slow now.

Hello Stephena,

No worries. If you uncheck the Number of processors box and apply, Windows 7 will use all processors/cores by default. :)

I wish I could remember specifically where I found the info, but I do remember reading a while ago that checking the box to use all processor cores in XP, Vista and 7 had a slight but definite positive impact during bootup.

When I installed XP and 7, and then enabled all cores, my bootup and loading times were shaved by a few seconds. Not a huge improvement, but measurable nonetheless.

My two centavos.

Hello Tom,

That may just be either a placebo effect, or something else that could be the cause of the slight improvement.

Whether unchecked (recommended) or checked and all selected, it will use the same all processors/cores, so it shouldn't make any difference. :)

I know this article is a tad old, but I thought I would share this link:

The placebo effect is powerful :)
