How to Change C:/Users/Username in Windows 10 [Easy Guide]
If you have ever set up a Windows computer in a hurry, you may have ended up with a user folder name like C:/Users/John123 instead of something clean and professional. Unfortunately, Windows 10 does not make it easy to change this folder name later. Simply renaming the folder can break apps, user settings, and even your ability to log in.
That said, there are safe and effective ways to change your C:/Users/Username folder name without damaging your system.
Let’s do this easily!
How to Change C:/Users/Username in Windows 10?

To change the C:/Users/Username folder in Windows 10, create a new administrator account, rename the user folder from another account, update the profile path in the Windows Registry, and then sign back into your updated account. This ensures the system recognizes the new folder name without causing errors.
Let’s go for detailed steps!
Step 1: Create a Temporary Administrator Account
Before making any changes, you need a second account with administrator privileges. This is necessary because Windows does not allow you to rename the folder of the account you are currently using.
To do this, open Settings and go to Accounts, then select Family & other users. Under the section labeled Other users, click on Add someone else to this PC. When prompted, choose the option that says you do not have the person’s sign-in information, then select Add a user without a Microsoft account.
Enter a simple username, such as TempAdmin, and create the account. Once it appears in the list, click on it, select Change account type, and set it to Administrator.
After this, log out of your current account and sign in using the newly created administrator account.
Step 2: Rename the User Folder in File Explorer
Now that you are logged in with a different admin account, you can safely rename the folder.
Open File Explorer and navigate to C:/Users. Here, you will see all user profile folders. Locate the folder with the name you want to change.
Right-click on the folder and select Rename, then type the new desired username. Make sure the new name is simple, with no spaces or special characters to avoid compatibility issues.
Press Enter to confirm the change. If Windows shows an error, double-check that you are not logged into the account whose folder you are trying to rename.
Step 3: Open the Registry Editor
Renaming the folder is only part of the process. Windows still references the old folder name internally, so you must update it in the Registry Editor.
Press Windows + R, type regedit, and press Enter. This will open the Registry Editor. You may be prompted for administrator permission, so click Yes.
Once inside, navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
This section contains all user profiles on your system.
Step 4: Locate Your User Profile Entry
Inside the ProfileList folder, you will see multiple folders with long names starting with S-1-5. Each of these represents a user account.
Click through each one and look for a value named ProfileImagePath on the right side. This value shows the current folder path for each user.
Find the entry that matches your old username folder path, such as C:/Users/OldName.
Take your time here, as selecting the wrong profile can cause issues.
Step 5: Update the Profile Path
Once you find the correct entry, double-click on ProfileImagePath.
Change the value from the old folder name to the new one you just created. For example, update C:/Users/OldName to C:/Users/NewName.
Click OK to save the changes.
This step tells Windows to use the new folder name when loading your user profile.
Step 6: Restart Your Computer
After updating the registry, restart your computer to apply the changes.
This step is essential because Windows needs to reload the user profile settings with the updated path.
Do not skip this step, as it ensures the changes take effect properly.
Step 7: Log Back Into Your Original Account
Once your computer restarts, log back into your original account.
If everything was done correctly, Windows should load your profile using the new folder name without any errors.
Open File Explorer and verify that your files, desktop, and applications are intact.
Step 8: Delete the Temporary Administrator Account
After confirming that your system is working correctly, you can remove the temporary admin account.
Go back to Settings, then Accounts, and select Family & other users. Find the temporary account, click on it, and select Remove.
This keeps your system clean and secure.
Step 9: Verify Applications and Paths
Some applications store file paths internally, so it is a good idea to test your frequently used programs.
Open apps like browsers, editors, or development tools and confirm they are working properly.
If any app shows errors, you may need to update its file path settings manually.
