So, lucky me, I got cumulative update 4 (Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3116908)) for Win 10, 1511 yesterday. Since then, my windows wireless service keeps stopping every few minutes and I have to reboot or use the networking troubleshooting to re-start the service. A little annoying to say the least. I've uninstalled the update and all seems well again.
The troubleshooting report says:
The Windows wireless service is not running on this computer
The Windows wireless service is also called the WLAN Autoconfig service.
Who else is having the same problem? Does uninstalling the cumulative update work for you too?
