Windows 7 & Core Parking .... a *better* way to Turn It OFF ....

Firstly major props to new forum member sky60234 for the following method.
 
Some of you will recall my previous regedit to turn-off Win 7 Core Parking here:-  http://forum.cakewalk.com/fb.ashx?m=1852473
 
This is now superseded by a much better method.   Thanks to  sky60234   there is now an  easier  / non-destructive  /  fully reversible  way to do this - ie: no deletions of .Reg keys needed - only an entry value adjustment.

 
________________________________________________________
 
In short, here is the better method from sky60234:-
 
- Go to Regedit
 
- Find this key:-  " 0cc5b647-c1df-4637-891a-dec35c318583 "
 
- Within this key, there is a value called:  " ValueMax "
 
- This value represents the % number of cores the system will park - the default 100%  ie:  all Cores are potentially park-able
 
- Change the value from 64 to 0 so the " ValueMin "  and  " ValueMax " are both zero
 
- You will have to find the key a few times and repeat the process for each time it is found - the number of instances will depend on the number of power profiles in your system  [  in my DAW it was only found twice ]
 
- Do a full shutdown and power-off and cold-re-start
 
________________________________________________________
 
 
I have tested the above on a clean Windows 7 x64 / Clean 8.5.1 install and it works perfectly - all Cores are available at all times and none are ever parked - the result  =  even CPU loads at all times regardless of loads.
 
As sky60234 noted, the advantage of the above is that nothing at all is being deleted from the Registry -  all that is being done is that a value is being adjusted.
 
Again, major thanks and props to   sky60234  for this excellent  fix.
 
Tom
