Fresh install of Windows 8.1 has messed up my user folder

[JaseUK]

Hi guys.
I have re-installed Windows as I got myself a new motherboard and graphics. However when I get to the point where I sign into my Microsoft Account I cant because I am not connected to the internet. So I created a local account and thought ah well I'll just delete that account when I install the drivers for the LAN and add my Microsoft account. So I've done that but Windows has named my user folder jaseu_000 and its annoying the hell out of me.
Its never done this before as I have always been able to sign into my Microsoft Account during a fresh install.

Any ideas?

I have just discovered WinReducer8.1 and am currently setting up an iso that will hopefully allow me to incorporate the Killer LAN drivers.

Well it worked I placed the Killer LAN drivers onto the slipstreamed dis and installed Windows 8 again. This time it allows you to sign into your account.
