I recently started using an old Windows 10 computer as the family computer in the kitchen (laptop named KitchenLaptop.) Since I was the only user, I just removed the password from my user account (user account was "rgm") to use it as the generic default account.
Windows 10 update changed things (gasp!) and created a new user account called rgm.KITCHENLAPTOP. This is now the default account, and I can't log out of the new account or log on as "rgm". All my files, settings etc are intact in the "rgm" user account, but it is a royal pain to manually access the folder every time I need something. To make matters worse, all the kids' bookmarks and shortcuts are on the "rgm" account.
How do SAFELY delete the new "rgm.KITCHENLAPTOP" account and restore "rgm" as the default, leaving all files and settings intact?
Windows 10 Home, 64 bit
