Yeah, Windows tries to constantly trick you into using a Microsoft account and storing your Desktop, Documents, etc in OneDrive online. The reason is simple: money. When you inevitably run out of space, you can't save anything else. And you can no longer use your linked Hotmail account. I had to explain to my Dad's 80+ year old neighbor why she couldn't email photos with her kids and then try and fix the messed up Windows settings to get her back working again. This type of behavior in software is honestly evil.
