Windows 7 Sleepblockers......and powercfg!

[Torben Andersen]

If a game or video is running, the computer will not go to sleep, which I want it to after the specified idling.

Is there any alternative to "powercfg" to manage sleepblockers? IE a graphical userinterface?

I cannot make "powercfg -REQUESTSOVERRIDE XXX" work, IE when a user has an audiostream:

SYSTEM:
[DRIVER] Realtek High Definition Audio (HDAUDIO\FUNC_01&VEN_10EC&DEV_0887&SUBSYS_1462D721&REV_1003\4&335f6b69&0&0001)
En lydstream er i brug i ›jeblikket.

What is the correct syntax for overriding this sleepblocker?

Thanks
