Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

Apparently lusrmgr.msc is not available in the Windows 8.1 version I'm using, and thus I can't change my username under the Local Users and Groups tab.

I would like to rename my user profile name so that the address line will display


and not

C:\Users\John's PC

How can I do that?

Are you 100% positive your user name contains a space because thats unusual. What version of Windows 8.1 do you have exactly update your question to with this information –  Ramhound Apr 29 at 13:40
Are you using a Microsoft or a local account to log into Windows? –  Ƭᴇcʜιᴇ007 Apr 29 at 13:55
@Ramhound Spaces are valid characters in Windows usernames. Seems to fit the same format of the auto-suggested PC name in newer versions of Windows too. –  HopelessN00b Apr 29 at 14:09
@HopelessN00b - It fits the name of the computer but not the username. Which is the reason I am trying to confirm. If you reply to my comments we won't get along. –  Ramhound Apr 29 at 15:43

As far as I know, you can rename your user in Win8.1, but the directory your profile lies in won't change to reflect the new user name! It will always stay the same as it was created.

Let's assume you named your user correctly ('John') in the first place, then handed your computer over to a friend named 'Heather' and she changes her profile name accordingly. From now on Windows will welcome her as 'Heather', but her user files will remain in the profile directory C:\Users\John!

The only way to circumvent this is to create a new user, transfer all files from the old user profile to the new one and then delete the old user profile.

True, but doesn't answer the question at all. –  Simkill Apr 29 at 14:41
False answer. It's possible to change default user folder. –  Jet Apr 29 at 14:59
@Jet: If there's an official way of doing this without fiddling with registry values (which should not be considered 'official' and should not be done by an unexperienced user), please let us know. –  Breit Apr 29 at 15:13
@Simkill - How does this not answer the question? It explains that even if the actual name of the profile is change the name of the profile directory won't be changed. –  Ramhound Apr 29 at 15:44
@Ramhound The question has changed since my comment. Originally the question asked how to change the username of a user as lusrmgr.msc is missing in windows 8.1, hence Jet's answer below. Instead of asking a new question like Mr. B was supposed to, he (or Indrek) has completely rewritten his question and made Jet's answer and my comment irrelevant. –  Simkill Apr 29 at 15:52

Just go to User Accounts and change your user name.

For Windows 8, do the following:

  1. Go to Desktop
  2. Move the mouse to the top-right corner of the screen (a side-window will appear)
  3. Go to Settings → Control Panel → User Accounts
  4. Select your user and change its name

For detailed instructions with screenshots, read this tutorial.

And if you want to change your default user folder, this article will help you. (restart or log out to fully apply)

-1 That does not change the user’s actual name, just the display name. –  kinokijuf Sep 1 at 5:32
