@MisuseCase If I had to guess, the feature is not compliant with Microsoft's own legal department's retention policy, and Microsoft's lawyers are about to scream about the fact that if MS gets sued, the blast radius for document discovery just exploded if they don't disable it internally.
@wrosecrans @MisuseCase I would be extremely surprised if this doesn't ship with a GPO to disable it.
(Also, MS not enabling group policy on consumer focused windows editions probably ranks alongside the Win8 start menu destruction as one of the worst design decisions they've ever made)
