How to rename C:\ users

I bought a new Toshiba laptop running Windows 8.1.Recently, I upgraded to windows 10.
But now I noticed that my user folder is named as it world. And the path is C:\Users\it world .
please help me to change it to C:\Users\Shraavan.Please..........

Here's how to do it... BUT... it takes a while and is quite involved.

Why not create another user, say Shraavan.
Make sure make Shraavanan is an administrator.
Copy/save your themes, files and/or settings over to Shraavan.
Log off then back on as Shraavan.
Now delete the old user account (it world).
