Introduction

There may be some Wake On LAN (WOL) issues with the recent upgrade to Windows 10. This article will help you find the issues and resolve them.

If you have a PC randomly waking up after upgrading to Windows 10, you can run this command in an elevated command prompt to see what last woke the computer up:

powercfg /lastwake

In my case, there were 2 issues: one is Windows has a scheduled task called mcupdate_scheduled which is set to wake the computer up. Here are steps on how to disable this:

- Open the Task Scheduler
- Navigate to Microsoft, Windows, Media Center
- Right-click the mcupdate_scheduled task, choose Properties
- On the Conditions tab, uncheck the box "Wake the computer to run this task"
Done!

I also had an issue with TeamViewer, which may be fixed with a future update. I even disabled the WOL feature within TeamViewer but it didn't help. The only way I was able to stop it was to go into Services and disable the "TeamViewer 10" service.

This will still allow you to use TeamViewer to connect to other machines, but will disable remote access to the machine itself, which is all I needed in my case. Other alternatives I use to connect remotely are Splashtop, VNC, and RDP.

I hope this info helps others!
