Upgrade issue Computer starts up by itself

A lot of topics on this subject so it is a real problem. But don't be so fast to propose just turning off wake on lan. Some of us are actually using it. And using it with older versions of Windows.
If that is indeed the problem I will try to disable mine for test these days after i exhaust oll other options, but if it turns out that it wakes without actually getting magic packet then it is a bug and I hope with more reports Microsoft should fix it.

CyberTod,

Some others also said they use it but in my case I wasn't and it fixed problem. I agree it is a software issue and Microsoft should issue fix so those who do will be happy. I did call Microsoft support first time I installed and tech was clueless. Hope my case report got them looking into problem.
From my understanding how computer wakes from 7 and 8 changed and apparently it's different with 10.
I had no problems with wake settings on 8.

This was the exact reason my computer would not stay asleep after upgrading to Windows 10. This box was checked during the upgrade process from 8.1. I unchecked box to wake computer and everything has been working great. Good Luck!

This solution worked for me - thanks for posting!
