Where is this documented? If I had been blinking I wouldn't have known about it. I later found it using Reliability Monitor. There are some Surface Pro updates on the Catalog, so maybe this will show up there some time but those aren't well described either. Another thing to perhaps be waiting for (I'm not going to hold my breath) is
Driver Information: Coming Soon
Ah. Judging by an earlier one It looks like a .cab file may have arrived with this. And the Reliability Monitor gives me a possible timestamp...

Is there such a thing for a Surface 2 Pro? My Screen cover is attached but because my tablet's orientation is Portrait the Screen cover is disabled. My keyboard is normally a Wireless USB but recently I have been using Remote Desktop Connection.
