I know that one can enable or disable wake timers on Windows Vista and later OS using PowerWriteACValueIndex or PowerWriteDCValueIndex APIs with the GUID_ALLOW_RTC_WAKE or {BD3B718A-0680-4D9D-8AB2-E1D2B4AC806D} from the GUID_SLEEP_SUBGROUP or {238C9FA8-0AAD-41ED-83F4-97BE242C8F20}
How do I do the same in Windows XP?

  • The bottom of this MSDN page describes the mapping between XP and Vista+ functions: http://msdn.microsoft.com/en-us/library/windows/desktop/aa373163%28v=vs.85%29.aspx – Hans Passant Dec 08 '12 at 14:33
  • @HansPassant: Thanks, I found it too. But that doesn't explain how to do what I want. Now I'm wondering if it's even supported by Windows XP? – ahmd0 Dec 08 '12 at 19:48
