I'm having a problem with Windows 7 not sleeping. I ran powercfg -requests and channels is the culprit. I do not have a web UI active. I have a FireTV but it is on the home screen, not currently running any Channels stuff. I tried to do powercfg -waketimers but I was told "An unexpected error condition has occurred. Unable to perform operation. You may not have permission to perform this operation." I opened the cmd window with run as administrator.
