Media Center PC won’t sleep through the night


I had a issue with my Media Center PC waking up randomly in the middle of the night.  While that might be expected of a young child, I do not allow that from my computers.  It turns out that there is a scheduled task associated with Media Center that updates the TV guide.  By default that task is allowed to wake the computer from sleep.


  1. Open up Task Scheduler and navigate to the Media Center configuration: Start > All Programs > Accessories > System Tools > Task SchedulerTask Scheduler Library > Microsoft > Windows > Media Center
  2. Right-click on “mcupdate_scheduled” and select “Properties”.
  3. Select the Conditions tab.
  4. Uncheck “wake the computer to run this task”.
(People with kids: what is the comparable command for children?)

To find out why your computer last woke (this is how I determined it was the Media Center scheduled task) run “powercfg -lastwake”
