To customize the Windows power schemes that ThrottleStop can access, try adding this information to the ThrottleStop.INI configuration file.
WindowsProfile1=8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c
WindowsName1=High Performance
WindowsProfile2=381b4222-f694-41f0-9685-ff5bb260df2e
WindowsName2=Balanced
WindowsProfile3=a1841308-3541-4fab-bc81-f71556f20b4a
WindowsName3=Power Saver
WindowsProfile4=
WindowsName4=Ultimate Performance
To find the correct GUID values, open a command window and enter this command.
powercfg -L
This will display the default power schemes and the appropriate GUID number that each power scheme uses. Copy and paste the GUID number into the ThrottleStop.INI configuration file and ThrottleStop will use the appropriate Windows power scheme. The optional WindowsName key allows you to name these 4 power profiles to whatever you like.
This new feature is optional. When this feature is not being used, ThrottleStop will default to High Performance, Balanced, Power Saver and Custom.
