Edge won't connect to internet, Skype for business won't screen-share, Windows Store won't update apps after Windows 10 version 1809 installed

Solution 1:

After digging a bit, it looks like the issue is related to IPv6 being disabled in the network connection settings.

Go to Control Panel\Network and Internet\Network and Sharing Center

Click on the 'Ethernet' link, or other network connection you are currently using. This should bring up the following window.

Next click on the 'Properties' button. Scroll down and make sure that IPv6 (circled below) is checked.

Once checked, close all the network windows and try to connect again with one of the Microsoft products that were previously not working. These apps should now work again.
