Manage Native Processor Performance Control

Windows includes built-in processor performance control to manage the microprocessor so it is more efficiently utilized. This tweak allows you to modify this feature.

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value, called 'HackFlags' and edit the value according to the settings below.

0 = disable native XP support
1 = use settings inherited from Intel software during XP upgrade
5 = system can support all modes when running on battery

Restart Windows for the change to take effect.


Settings:
System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\P3\Parameters]
Name: HackFlags
Type: REG_DWORD (DWORD Value)


Note: This tweak only applies to processors with either Intel SpeedStep or AMD PowerNow! processor performance control technologies.
