C #: Switching between nutrition plans

Question

I am creating an API and I want to switch between power plans

[Balanced, high performance, power saver]

my problem is not in the code, the coding is simple, but I want to know where I can find these force planes .exe files or even registry values ​​to change it.

Answer 1

Raymond Chen last post happens about this and he suggests the following:

If you are using Vista or higher, from a command prompt, run:

powercfg -aliases

However, this does not work for me, as -aliasesit is not a valid switch in Windows XP.

EDIT. GUID!
