As many of you may be asking, how do I unpark cores on Windows 10????
Well the new key on regedit is here:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\PowerSettings\0012ee47-9041-4b5d-9b77-535fba8b1442\51dea550-bb38-4bc4-991b-eacf37be5ec8
Be sure to set ValueMax and ValueMin to 0 then you will have all your cores unparked
Hope this helps.
