Hi Folks,

I had been struggling with my Windows 10 install, my machine wouldn't go to sleep and booted itself up automatically.

I have been trawling this forum and a few others and none of the advice worked. Yesterday the problem went away and I thought it might have been a glitch and thought no more of it. Today my eldest son booted his machine and mine booted too, so I turned his off, shut mine down the booted my wife's laptop, my computer booted too.

Turns out if you have a network with multiple devices and file/printer sharing the other devices can wake your machine up.

Solution: Goto Device manager > Network adapters > Properties > Power Management and uncheck "Allow this device to wake the computer" and "Only allow a magic packet to wake the computer"

That solved the issue for me. I have seen many others struggling and hope this is of some help. Sorry if it's old news or a well know fix. :)
