Misspelled users name in C: Drive

Go to computer, then look for your drives, then just click once on the C drive, don;t open it, then right click on that drive and then select rename. Then just correct the name to what you think it should be.
 


In file explorer, I go to desktop-C: drive-users then in there, there is my misspelled folder and another folder called public. When I right click on my misspelled user there is no rename option.
 


How do I do this excatly
