Windows 7: Desktop is Turning on Unexpectedly

Desktop is Turning on Unexpectedly

I have a Windows 7 desktop that is turning on unexpectedly. Some facts:

- My goal is to keep WOL configured and to prevent the unexpected starts. I do not wish to permanently disable WOL.
- I don't know how long these unexpected starts have been occurring. I do know that they have been occurring for at least 3 days.
- I have 2 NICs configured in a Team
- I have WakeOnLan configured in the BIOS and on 1 of the 2 teamed NICs
- As expected, the system wakes properly when I send a MagicPacket.
- I have a Windows 10 Desktop (different hardware, but same configuration). It does *not* turn on randomly.
- I have ruled out virus, malware, etc.
- I have no customized tasks, however I am unsure how to check if any default tasks may be causing the issue.
- I have used powercfg to check for any WakeTimers and there are none.
- When I run "powercfg -devicequery wakearmed", it only returns the one network adapter with WOL configured, as expected.

Does anyone have any suggestions? One specific question that I cannot find an answer to: Are there any Windows logs that will tell me exactly why the system started? (ie. WOL, manual Power On, etc).

Thanks in advance for the help!

See if this tutorial helps:

I use NirSoft TaskSchedularView for working with Scheduled Tasks.
It's easier to see what ran and when for all tasks, has search capability and more.
Task Scheduler Viewer for Windows 10/7/8/Vista
Also, I have Allow wake timers disabled in Power Options/Advanced settings/Sleep.
This prevents Scheduled Tasks from waking the PC for me.

If none of my ideas help and no-one else has better suggestions, i would temporarily turn off WOL while troubleshooting.
That might help find out if something else is sending a magic packet i don't know about, causing this.
