# Name of user profile folder on Windows 10

I recently installed Windows 10 on my machine. I logged in with my Microsoft account, as usual. But I noticed something strange: instead of being named "Thomas" as in Windows 8, my profile folder (in C:\Users) is named "thoma". It's not very important, but it's slightly annoying. What could have caused that? Can I change it somehow, without breaking everything?

(I'm not talking about the display name, which is "Thomas Levesque", as expected; I'm talking about the actual folder name in the file system)

As an aside, there is no direct way to change the display name of the local account; you would have to go to Computer Management -> Local Users and Groups and set the Full Name.
