Never tempt fate, I guess.
Spent my lunchbreak working on my Surface Book. Uninstalled Visual Studio after having failed to find the time to complete the Xamarin Challenge, got back to the office, installed the latest Creator’s Update update and drivers, rebooted and, because I was clearing space, ran Disk Cleanup. Rebooted.
The error: critical_service_failed. Couldn’t get into Windows, couldn’t get anywhere, really, the device was just stuck in a bootloop, tried to recover, and failed to do so, even with System Restore.
But it has at least given me a chance to test out Microsoft’s “Recover from the cloud.” 2 thumbs up on that: boot into recovery, give it the bitlocker unlock code and wifi credentials, and let it go. The down side is it wipes out Windows. So I get to be Paul’s anecdote of one, I guess: Creator’s Update seems to have blown up my Surface Book. The lack of other such reports suggests to me that I’m the outlier, this time. Probably payback for the problem free time I had with the Anniversary Update.
