My windows 8.1 desktop has suddenly decided to start itself during the night. It has not done that before and I suspect the behaviour might be new since new year.
1st of january 2015, it started 0615 (CET) - I thought it was odd and maybe a virus but did not investigate it further.
2nd of january 2015, it started 0550 (CET) - now I did some investigation. The following is what I found:
When runnning from cmd: schtasks/query
Scheduled Start 2015-01-02 07:23:58 Ready
Scheduled Start With Network 2015-01-02 07:23:04 Ready
Then I looked at task scheduler and I can see that "Maintenance configurator" has multiple triggers defined. This is what triggered the start this morning.
Then I had a look at: C:\Windows\System32\winevt\Logs\System.evtx
And there it says a lot of things which took place between 0447-0550. According to the logs it did boot (but didnt awake me) at 0447 and 0550 (here I did wake).
Here is some of the events from System.evtx:
The system time has changed to 2015-01-02T04:50:34.500000000Z from 2015-01-02T03:49:24.927685700Z. Change Reason: System time synchronized with the hardware clock.
The system has returned from a low power state. Sleep Time: 2015-01-02T03:49:23.470269100Z Wake Time: 2015-01-02T04:50:34.910310900Z Wake Source: Unknown
Process C:\Windows\System32\svchost.exe (process ID:3028) reset policy scheme from {381b4222-f694-41f0-9685-ff5bb260df2e} to {381b4222-f694-41f0-9685-ff5bb260df2e}
Windows Defender cant find any threats. Have I gotten some malware or virus? How come Windows suddenly decided to start doing maintenance in the middle of the night? It has not happened before. The computer has been without electricity for about 1½ week prior to this as I have been away.
