How to Change C Users Username in Windows 10


User profiles, which house crucial files, configurations, and private information, are kept in Windows 10 under the C:Users directory. Windows offers a default username during initial setup, but you can subsequently discover the need to modify it. With the help of this tutorial, you can easily change the C:Users username in Windows 10 without worrying about losing any data.

Understanding the Importance of Usernames

The username connected to the C: Users directory is important since it serves as a representation of your user profile and may be found across your computer. To prevent any future issues, changing it demands cautious thinking.

Backup Your Data Before Making Changes:

Backup all of your key files, directories, and data before making any changes to avoid inadvertent loss or corruption. To safeguard the security of your data, create a second backup on an external storage device or cloud service.

Create a New Local User Account:

You must establish a new local user account with the appropriate username in order to alter the C:Users username. The previous account will be replaced by this new one. To establish a new user account, adhere to following instructions:

  • Open the Start menu and go to "Settings."
  • Click on "Accounts" and navigate to the "Family & other users" section.
  • Select "Add someone else to this PC" or "Add a family member."
  • Choose "I don't have this person's sign-in information."
  • Click on "Add a user without a Microsoft account."
  • Enter the new username and a secure password.
  • Follow the on-screen instructions to complete the account creation process.

Transfer Files and Settings to the New Account:

You must move your files, directories, and programmer settings from the old account to the new one after creating the new user account. Take these actions:

  • Log in to the new user account you just created.
  • Open the File Explorer and navigate to the old user account's directory (C:\Users\OldUsername).
  • Copy all the necessary files and folders to a safe location.
  • Paste the files and folders into the corresponding locations in the new user account's directory (C:\Users\NewUsername).

Delete the Old User Account:

You need to erase the previous user account in order to finish the username change procedure. Please be aware that doing this will delete the account and any related files forever. Before continuing, make sure you have transferred all relevant data. To erase the previous user account, adhere to following steps:

  • Open the Start menu and go to "Settings."
  • Click on "Accounts" and navigate to the "Family & other users" section.
  • Select the old user account and click on "Remove."
  • Confirm your selection and follow any additional prompts to complete the deletion.

Finalizing the Username Change:

The user profile directory must then be renamed to match the new username after the old user account has been deleted. Take these actions:

  • Open the File Explorer and navigate to the C:\Users directory.
  • Locate the folder with the old username and right-click on it.
  • Select "Rename" and enter the new username.
  • Press Enter to save the changes.

User Profile Migration Tools:

User profile migration tools can be used if you need to move a lot of data or complicated settings to the new user account. By seamlessly transferring files, settings, and preferences from the old account to the new one, these solutions streamline the procedure. The User State Migration utility (USMT), a built-in utility provided by Microsoft, might be useful for power users or IT specialists.

Windows System Properties:

You might occasionally need to change the username that appears in Windows System Properties. Follow these steps to accomplish this:

  • Right-click on the "This PC" or "My Computer" icon on the desktop or in the File Explorer.
  • Select "Properties" from the context menu.
  • In the System window, click on "Change settings" under the "Computer name, domain, and workgroup settings" section.
  • In the System Properties window, click on the "Change" button next to "To rename this computer or change its domain or workgroup, click Change."
  • In the Computer Name/Domain Changes dialog box, enter the new username in the "Computer name" field.
  • Click "OK" and follow any additional prompts to apply the changes.

Impact on Installed Applications:

Modifying the C:For some installed programmers, a user's username may be important. Based on the username, several programmers keep user-specific information and preferences. You might need to update or adjust settings inside those programmers after changing the username. In order for a programmer to function properly with the new username, it may also need to be manually reconfigured or reinstalled if it depends on the absolute file path.

User Account Control (UAC) Considerations:

Windows has a security feature called User Account Control (UAC) that aids in preventing unauthorized changes to your computer. You could receive requests from UAC to confirm administrative activities while changing the login. Make sure you grant the required rights or credentials in order to move on with the adjustments.

Potential Impact on Network Shares:

Changing the username may make it difficult to access network shares or shared folders on other machines if your user account has previously been used to do so. You might have to modify the network sharing password or change the access rights on the distant PCs or servers to fix this.


Although changing the C:Users username in Windows 10 might be a difficult operation, if you follow the instructions in this article, the transfer will go smoothly. Remember to establish a new user account, move your files, remove the previous account, and rename the user profile directory. You should also make a backup copy of your data. You may use this to change your username while keeping all of your crucial settings and data.
