Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.


The function replaces any existing global power policy settings. Each user has a separate global power scheme, which contains power policy settings that apply to all power schemes for that user.

Starting with Windows Vista, use the PowerEnumerate function to enumerate power settings for a specified scheme and the power write functions to write individual settings.

For more information on using PowrProf.h, see Power Schemes.
