After installing the 2018-3 Cumulative Update for Windows 10 Version 1709 for x64-based systems (https://support.microsoft.com/en-us/help/4088776/windows-10-update-kb4088776) yesterday on my Dell Windows 10 Pro system I can no longer access the Internet using either Google Chrome or Mozilla FireFox. Edge and IE continue to work.
Both FireFox and Chrome claim to be blocked by the Windows Firewall or Proxy server, but I checked my settings and both are allowed and I even went as far as to turn all of Defender off - still no luck.
I also tried in-installing, restarting my system, re-installing Chrome and FireFox - still no luck getting Internet access.
Is the 2018-3 update broken and should I just remove it from my system since everything worked till it was installed?
Not sure if it matters, the prior update installed on the system was 2017-12 for 1709 and all was running fine.
