Fix: Not Entering Standby Automatically

[CMoya]

Just want to post this for folks who have problems with MCE not entering
standby automatically. Check your print job queues... both for printers or
for any of the virtual printers (like Adobe Acrobat etc).

For the past few weeks MCE would not go into Standby automatically
(manually, Standby worked fine). After seeing all the posts and trying all
sorts of "fixes" I realized what the problem was. There was a document in
the print queue. I missed it because I'm used to Windows putting an icon in
the tray for a print job or automatically trying to print the document when
it restarts. But no.... it was just sitting there. I deleted the stalled
print job and voila! MCE goes into standby after X minutes just fine now.

Funny I just saw this and thought of the issues I've been having. For past
2-3 weeks our normally reliable Vista Premium PC has recorded but not
returned to standby. Power options have made no difference. I've sat and
watched the processor clicking over at maybe 1 or 2% but still it refused to
sleep. I can manually set it to sleep no problem. In desperation I
completely re-installed Vista but it's made no difference. I've since
re-installed again but no difference. I wasn't aware of others having
recently suffered the same issue but I can't work out why its behaving this
way now.

Turns out my issue is Xbox 360 related. See 'Installed XBOX 360 Extender
