    Thanks Brian. Always good to come here and get notification of these updates – really appreciated.

    By the way, have you been having late nights? ‘Cause “…for more detailed conversations make sure to hope in our new and improved Windows 10 Forums.” Yep, I’m “hoping” a lot that Microsoft doesn’t mess up my laptop or PC!

    Love the forums section because it’s there that I get my hope and inspiration when dealing with Windows 10! Lol and thanks again – all good with the updates, so far!

    This update broke group policy. Just made a change and did gpupdate and now it’s not pulling any group policy at all.

    Win-10 update broke the wireless function on my Dell laptop. After updating, I have no wireless connection on startup and have to run the Troubleshooter to restore connectivity. Each time the troubleshooter reports that it has ‘fixed’ the network adapter (but it doesn’t stay fixed as I have the same problem and get the same results on the next start-up).

    Same here. The Wireless function was broken after the KB3163018 update. (On the WPA2 connections.) The only solution was to uninstall the update.

    Both wireless and wired network functions were broken by this upfate in my Fujitsu laptop. Constant booting when network connections are used. Uninstall helps.
