I have two PCs - desktop and brand new Surface Book - running Windows 10 Pro Insider Preview Version 14379. When I start Surface Book it gives me a "This build is about to expire" error message. Desktop books perfectly - no problem.
When I run Winver I get two different expiration dates:
Desktop PC
Surface Book
Tried everything - rolling back, updating, repairing, no effect.
This is obviously VERY annoying since there's so way a new Surface Book could possibly have an unauthorized or expired copy of Windows.
Suggestions?
