Hi,
I updated my desktop (Asus P9X79LE with Realtek GBE Ethernet) last weekend from Windows 7 to Windows 10, and then I struggled for several days to try to get WOL/Wake-on-LAN working on it after that (WOL worked when it was running Win7, but didn't work after installing Windows 10). I actually gave up several times, but I finally got it working, so I figured I'd drop this nugget of knowledge here, in case anyone runs into this problem... and maybe this might help.
So what finally helped was this:
https://serverfault.com/questions/91297 ... and-hidden
and on my machine, I just had to add the S5WakeOnLan DWORD under CurrentControlSet and set it to 1, and then it started working!
Anyway hope this helps someone.
Later,
Jim
