My SB4 did the update last Wednesday April 20, 2016, and was very surprised on how well it has been operating.
DOCK WORKS !!!!! OMG that investment I mad in Dec finally can be used. I have my LG Ultra Wide Monitor via DP to the Dock, and plug in and works. No blanking the screen, no moving the cable back and forth from the the Surface to the Dock, just works.
Now the concern... I 'hibernated' the Surface @ home on the Dock, got to work, plugged into the Dock @ Work.... BSoD.....
It is Windows, and only the 3rd one ever, no need to panic....
The the odd thing, on Reboot, it went to
but upside right. It was Orange / Yellow, and I checked there were no updates applied today....
IS this telling me that the SYSTEM UPDATE did not apply last week?
