PC waking up randomly

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.

@DavidPostill, it's not. – user626528 – 2015-08-06T13:03:49.317

If you set windows Update to Manual Install does it still wakeup? From your question wuauserv is Windows Update Service. – albal – 2015-08-06T14:29:56.800

@albal, it didn't help. The last wake reason is still the same. – user626528 – 2015-08-06T14:41:57.783

1@user626528 did you reboot for that change to be effective? – albal – 2015-08-06T14:43:24.390

@albal, it seems this have solved the problem. It's strange, because the option to wake up for updates installation was turned off. – user626528 – 2015-08-07T02:41:40.347

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 – 2015-08-07T08:26:25.703

I had the same problem: powercfg -lastwake: wuauserv

maybe something to do with error 0x80070057 in windowsUpdate.log.>> ou yes, https://www.youtube.com/watch?v=Y6eHDtylDYo this will fix, the first steps at least, remowing some files from folders. at least didnt not wake up, after waiting

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!
