After failed Sears and Roebucks, I think Microsoft is the #2 company of all time for "the right hand doesn't know what the left is doing." It's notorious that they have a hard time replicating products that competitors make look simple: look how the Steam store really works for for games, or how Dropbox works so much better than Onedrive.
I just finished spending more hours than I want to count trying to clean my dad's PC of all licensing and account connections to his former employer's use of Office and OneDrive and onto his personal account and license. In hindsight I wish I had just nuked and paved it, or bought him an iPad with keyboard and mouse.
