The Original Surface Book

Microsoft started rolling out Windows 10 with version 1803 to Windows Insider users in the Release Preview ring last week. For Surface Book users, if you have updated to the version in the Release Preview ring, you might notice system instability and problems when detaching the tablet section from the base.

With the new Cumulative Update 10.0.17133.73 build for Release Preview, Microsoft also forces you to install a firmware update labeled “Surface – System – 3/4/2017 12:00:00 AM –” to fix those problems.
