I'm looking for a way to limit the CPU usage by any application on Windows 7 to 50%. I've tried searching the Internet for a way to do this, and it looks like this is an easy thing to do on Linux and Mac OS X (one command in the terminal) but I'm not sure how to do it on Windows 7. Any help would be much appreciated. Thanks!

In Windows 7, exit Task Manager and open msconfig.exe via Windows Search or the Run dialog (Windows key + R). In the System Configuration window, head to the Startup tab. Now find startup items correlated with the items that you noted. Uncheck them, click okay, and then restart your PC.
In the Power Options window, expand Processor power management, and then expand Maximum processor state. Now click on On battery and set the maximum threshold value for CPU utilization.
You can use BES. It throttles CPU-hungry applications when asked. You can limit 3 programs maximum. I use this to run multiple online game clients and it works like a charm for me. You should run it with admin privilidges and in windows xp sp3 compatible mode. To adjust these settings, right click on the executable and chose options.
Here's the link for BES - CPU limiter.
