    CPURateLimit which works in server 2008 R2 seems to be broken (or of null effect) in server 2012 and Windows 8

    So per 

    http://technet.microsoft.com/en-us/library/ff384148(v=ws.10).aspx

    this should work (and we have it working on 2008 R2.

    Is this a known issue or documented anywhere.

    the only place i've found that mentioned this at all is the post

    I’ve not yet found a official document from Microsoft about CpuRateLimit in Windows 8/Windows Server 2012. Seems this function has been discarded in Windows 8/Server 2012.

    it works for win7 and 2008 R2, and here is the docs for 2008 R2

    i can't find anything about 2012. However i just remembered that it doesn't work until after a reboot after you set the registry key, and i'm not sure if i did that in my 2012 test. so i'm testing that now.

    I did the reboot and made sure the registry key was there, and was for the right sid, and still it doesn't work in 2012. the CPU for my test process is still pegging out from 80% to 99% , despite the registry key saying this user should throttle to 15% (which works on server 2008 R2)
