Windows 7 - Processors - Limit Number Used by Windows 7

Hello Max,

There is no need for this to be removed since it can be very helpful to those that need it. Even for inexperienced users, this tutorial is layed out easily enough for them to be able to set it back to default.

The default is to have the box unchecked instead to use all processors/cores. It does not matter what the number is in the drop down list when the box is unchecked since that number only matters when the box is checked to limit the amount of processors/cores to that number.

I agree that this setting should be left alone to it's default of being unchecked unless you have a need to limit them for testing purposes.

Okie dokie, your the head honcho. However, I'm thinking that maybe it should be clear in the first post that this setting only affects users who are running two different physical processors, and it has no affect on single CPU's with a dual or quad cores. It seems like people are getting confused as to it's actual purpose, and function.

No problem. It can reduce the amount of both multi-core processors as well as multi physical processors used by Windows 7 though. I tested this myself on my single quad core CPU, and it reduced the CPU Usage History graph in Task Manager to how many I limited it to.

Hmmm, that's odd. I've had both my cores in the CPU history graph since installation.

By default you would have all cores available.

In the boxed in red area in the screenshot of my Task Manager with my single CPU with 4 cores below is what is reduced by the number I set if I check the box in this tutorial and set the number of processors/cores to use instead.

Yeah I got what you were saying. However, I still cringe at the prospect of n00bs messing around in advanced system settings. Call it a quirk.

Oh, ok.

Well, they have to learn some how, and we can help to hear.

brink,it I check make all boot settings permanent,will I be able to change settings boot settings later??

Hello Manjunath,

Yes, you can still make changes to this at anytime that you would like afterwards, and check the box again afterwards. It's just to make it the new default startup process.

Unless you are doing testing by limiting your processors, you should leave the Number of processors box unchecked so that Windows 7 uses all available processors/cores by default.

Hope this helps,
Shawn
