How know directly which signal wakes up a computer?

Question

I am turning my Windows 8 box into hibernate for night. But at morning I am finding it wake up. I know I can use trial and error method to find what is turning it on. But is there any registry, which remembers wake up signal, which woke up a computer this time?

You can open a command prompt and run powercfg -lastwake.

You can do this in a batch file like this:

lastwake.bat (put it on your desktop for easy access)

powercfg -lastwake
pause

At the Wake Source it should state your wake-up source.
