Right now fixing another problem after ugprading to Windows 8.1 but I think this is the setting problem and it seems once I upgrade the NVidia display card drive on my PC (but should not related), my IE and the Windows store seem can't connect to the internet at all, which I can few minutes ago.
Chrome can surf the internet, and ONCE VPN connected, it can !!
How can I troubelshoot it?
any setting in Windows 8.1 / IE 11 can check, I just relocated the IE history to somewhere else !!
