I just re-installed Windows 8.1 Pro and I noticed something strange about my home directory folder C:\Users\Username. The name of the folder instead of being Username is Usernam_000 C:\Users\Usernam_000. Why is that? Is this normal behavior? If not how can I change its name?
Edit 1:
As I have said in a comment all of these answers in the questions you provided as duplicates just say ways of changing the name. My principal question is why this happened. I want a way to change the name only if it is a normal situation and not a problem.
Edit 2:
As I am really curious about this "problem" I did another installation of Windows 8.1. The same thing happened again, although I deleted the partition and formatted it again.
