Specs: Windows 8.1 64 Bit, AMD FX-8350 8 Core @ 4.0 GHz w/ 2x4 DDR3-1600
Hey Everyone,
I was wondering if there was a way (preferably without having to download anything) to limit the amount of CPU used by a single program. I know it isn't possible in Windows 7, but I was wondering if Microsoft added something that could do this in Windows 8.1.

If not, could you guys suggest some good programs that could do this?

Thanks!

It is under the "details" tab of task manager

You can also see details by right clicking on a "process" and clicking "Go to details".

Not sure if this will help but you can set the priority in Task manager. Press CTRL+Alt+Del and go to the Processes tab. Right click on the program and hover over Set Priority, then select the level you want.

I believe that even earlier versions of Windows had this capability but there is no utility provided to control this. There is most likely a third party tool to do this but I have no experience with such.

Usually this kind of thing would be managed with setting CPU priority. But if there is only one CPU bound process running (the typical case) it will receive virtually 100% of CPU time no matter what priority you set.

Under task manager you can use "set affinity" to force a program to only use a certian number of cores (multi-core CPU only).

This can give the effect of limiting the programs CPU usage (1 / 4 cores will mean the program can only use 25% of the total CPU power at max).

What about for windows 8? As far as I can tell it won't let me set priorities. I tried right-clicking the process, but nothing happens...
