PC waking up randomly

Question

My PC wakes up randomly after I put it to sleep, in different periods of time (typically after a few minutes). I've tried to disable all possible wake up reasons, but to no avail.

D:\>powercfg -lastwake
Wake History Count - 1
Wake History [0]
  Wake Source Count - 1
  Wake Source [0]
    Type: Wake Timer
    Owner: [SERVICE] \Device\HarddiskVolume2\Windows\System32\svchost.exe (wuauserv)

D:\>powercfg -waketimers
There are no active wake timers in the system.

D:\>powercfg -devicequery wake_armed
HID Keyboard Device
HID Keyboard Device (002)

Any ideas how to fix it?

UPD explanation for paladins of purity: I've tried all usual ways of solving this problem and none helped. And it doesn't happen on schedule.

If you set windows Update to Manual Install does it still wakeup? From your question wuauserv is Windows Update Service. — albal, Aug 06 '15 at 14:29
@albal, it didn't help. The last wake reason is still the same. — user626528, Aug 06 '15 at 14:41
@albal, it seems this have solved the problem. It's strange, because the option to wake up for updates installation was turned off. — user626528, Aug 07 '15 at 02:41

The last wakeup event is for wuauserv which is the Windows Update Service. If Windows Update is set to Manual rather than a specific time of the day then this should prevent Windows Update Service from waking the machine.

It's strange, because the option to wake up for updates installation was turned off. Switching settings to "Choose what updates to install" solves this problem too. – user626528 Aug 07 '15 at 08:26

I was experiencing the same issue for a few months now. I was able to resolve it by installing a Microsoft hotfix which is the latest update to the System Update Readiness Tool. See the following KB:

Since installing the SURT update yesterday, there have been NO errors in Windowsupdate.log, and the PC has not woken up by itself once!
