更改当前电源策略（使用SetActivePwrScheme API函数），自定义电源按钮动作（设置GLOBAL_POWER_POLICY）

#include <windows.h>

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPreInstance, LPSTR lpCmdLine, int nShowCmd)

    GetActivePwrScheme(&uiID);
    ReadPwrScheme(uiID, &PwrPolicy);

    PwrPolicy.user.VideoTimeoutAc = 0;
    PwrPolicy.user.VideoTimeoutDc = 0;

    WritePwrScheme(&uiID, NULL, NULL, &PwrPolicy);
    SetActivePwrScheme(uiID, NULL, &PwrPolicy);

    return 1;
