Microsoft Surface Book update history | Surface firmware updates Looks like there hasn't been any SB (or SP4) firmware updates since February 2016 (whereas previously there have been consistent updates every month since October 2015). Will we likely see updates by end of March or early April? I have a few newly purchased SB's to set up for family members. But with all the potential problems (ex. wake to blank screen from Feb update), I'm nervous about even starting. Would prefer to start with the very latest patches that Microsoft may have in the works.
