Anyone know where I can find a program that can limit this for Vista? Currently, I'm using BES but it only works in 2k/XP.

I'm running 7 or 8 virtual routers and switches on my desktop and would like to limit the amount of CPU usage that the program uses.

Any help would be great! I've tried to search google and technet, etc but I haven't found anything.

Why don't you just lower their priority?
