I have removed Microsoft Account in 1909, but that prevents activation. Removing files (manually) doesn't break activation, and I see that something in registry is deleted, so that prevents activation (also error suggests that some registry key is missing).
Or, to have option to remove custom files? We aleady have list of files that should be skipped during removal.
