Microsoft appears to be prepping for a new cumulative OS update 10586.104 for Windows 10 being readied for release next week, likely on February 9 or ‘Patch Tuesday’.
No new features are expected with the update, but there should be the usual fixes and general OS improvements including for Surface (the last .71 update also had some Surface fixes too).
The PC update is a general release for all Windows 10 PCs and is separate from the PC Insider program, which is now on the Redstone branch with the release of build 14257 last night.
