Hello!  If you are using Windows 8.x or 10, when you first create a Microsoft account or use your existing account to log into the computer, it creates a folder that is partially your user name for your account.  As far as I know this cannot be changed unless you create an off-line account.
Just wondering how that name after C:\user was generated please. I don't recall being asked for a username during setup and would like to know if it can be changed easily. It just seems to have taken the first part of my email address and used that. Many thanks.
Where did the user name after C\:user\ come from please?
