Greetings!

I want to implement the following feature: make miner consume only a specific number of CPU resources, threshold for which is determined by overall CPU load (i.e. use only up to a half of available computing power). In Linux it should be not that hard, however, I want to compile it for Windows.
Could you please aim me, which articles and books should I read regarding that, since I don't want to use any third party programs?
