New Windows Guides
Hello,
My problem is that Windows 7 unintentionally wakes up from sleep mode every day between 21:30 and 22:00, even though I have deactivated all relevant devices in the device manager under power management. - The input command powercfg -lastwake does not help either, as only the following information appears there: Activation history -1 / Activation history (0) / Activation source count - 0
My event display shows the following:
Log name: System / Source: Power-Troubleshooter / Event ID: 1 / Reactivation source: Unknown
I have tried to find out the device ID with "Devcon.exe", but unfortunately this does not work under Windows 7. Is there any other way to determine the reactivation source?

Hello Gerd,
Another source for this self-awakening (which I also struggle with every few days on my Media Center PC) are the Scheduled Tasks of Windows 7.
There are dozens of these tasks in total, so it will be a bit of a chore to plow through them all and check which one is really responsible for reactivation. This is how it works: Open the Start menu, type in "Task Scheduler" and press Enter. Now you have to proceed systematically: Now go through all third-party tasks, which can be found by clicking on "Task scheduling library". Double-click on an entry, such as "Java Update Scheduler" and check under "Conditions" whether "Reactivate computer to run the task" is ticked.
Now repeat this with all tasks, especially with the tasks in the subfolders such as "Microsoft\Windows" or "WPD".
Let me know if this has helped!
Looking forward to your feedback,
Sandro Villinger
Hello Sandro,
It's done! After a lot of searching and trying, I have finally found the culprit. As you rightly suspected, it is hiding in the task scheduling library. It is "Mcupdate_scheduled", which can be found under Microsoft / Windows / Mediacenter. After unchecking the "Reactivate computer to run the task" box, the PC will no longer wake up unintentionally.
You have helped me a lot. Thank you.
Best regards
Gerd
Hi Gerd, I'll probably make a tip out of this soon - good tip with the Mcupdate. Why did Microsoft set it up like this? Are Media Center updates SO important? Couldn't it have been set so that the PC automatically goes back to standby afterwards?
Great tip!
Greetings, Sandro
Hello Sandro,
I apologize if my request does not quite belong here. - After my first positive experience with Windows tweaks, I registered and tried to access this page. Unfortunately, I was unable to do so either in the help forum or in the Win Tweaks blog. I could not find a suitable link, and the entries I made in the search field did not yield any results. Thank you for a quick tip and
Greetings
Gerd
