It should have been straightforward: I was updating The Windows 10 Field Guide last weekend and wanted to choose a chapter that would be easy to update. The Backup and Recovery chapter seemed like an obvious choice: Surely these age-old tools haven't changed in any meaningful way between the last two Windows versions. Right?

Wrong. Microsoft, in fact, made a subtle but dramatic change to the Windows 10 recovery tools between versions 1703 and 1709.
