Change the Case of a User Logon Name
I need to change the case of a user’s logon name from TUser to tuser. Seems simple enough but turns out there’s a little trick.
I open up the properties of the user & select the Account tab.
I change both fields to tuser & click OK.
I open the properties again to double check & notice that the User logon name (pre-Windows 2000) changed but User logon name did not.
The trick is to rename the account without actually renaming it. Right click the account & select Rename.
Now retype the name exactly how it currently is & press Enter. So in my case I just type Test User & press Enter. That will bring up the Rename User dialog box. From there change the case in the User logon name textbox (& pre-Windows 2000 if not already done) & click OK.
Look at the properties of the account & the case had been changed.
