And I'm now on refreshing build 10061! Don't know what the problem are, I was just try to install an Network Printer, no problems in any other build, and Laptop restarted and the whole network were not accessible anymore. Now I'm on refreshing, only option which I was getting and will see that wil work and bring back Networking again. Both were down: Ethernet and WiFi, even indicator were showing all works. Try to connect to internet and other computer and got the Messages that Network is disconnected! No Problem, because I really wait for the next official MS Build anyway.
