Changing your name on a computer can mean different things depending on context. You might want to rename your user account, change the computer’s device name on a network, or update your personal name in various applications.
This guide will focus primarily on how to change your user account name and device name on popular operating systems such as Windows and macOS.
Understanding the difference between user account name and computer name is essential. The user account name is the identity you use to log into the computer, while the computer name is the device’s name on a local network.
“Your computer name helps other devices identify your machine on a network, while your user account name is your personal login identity.”
Changing User Account Name on Windows
Windows allows you to change the user account name through different methods depending on whether you are using a local account or a Microsoft account. Below are step-by-step instructions for each.
Method 1: Change Local Account Name via Control Panel
This method works if you use a local account (not linked to Microsoft online services). Follow these steps:
- Open the Control Panel by typing it in the search bar and pressing Enter.
- Select User Accounts.
- Click User Accounts again, then select Change your account name.
- Enter the new name you want and hit Change Name.
- Restart your computer for changes to take effect.
Note: This changes the display name only; the actual user folder name in C:\Users remains unchanged.
Method 2: Change Microsoft Account Name Online
If you log in with a Microsoft account, your name is synced from your Microsoft profile. To change it:
- Open your preferred browser and go to https://account.microsoft.com.
- Sign in with your Microsoft credentials.
- Go to Your Info tab.
- Click Edit name under your profile name.
- Enter your new first and last name, then save changes.
- Restart your PC to see the updated name.
Method 3: Rename User Folder (Advanced)
The user folder under C:\Users will retain the original name unless manually changed. Changing this folder’s name is complex and can cause system issues if done incorrectly.
It involves creating a new user account or editing the registry.
Recommended approach:
- Create a new local user account with the desired name.
- Transfer your files to the new account.
- Delete the old account if no longer needed.
This method ensures the user folder matches your chosen name.
Changing Computer Name on Windows

Changing User Name on macOS
macOS uses two main names associated with your user account: the Full Name displayed on the login screen and the Account Name (short name) which is tied to your home folder.
Change Full Name (Displayed Name)
This is the easiest and safest change to make.
- Click the Apple Menu and select System Preferences (or System Settings on newer versions).
- Go to Users & Groups.
- Click the padlock icon and enter your administrator password.
- Right-click (or Control-click) your user name in the list and select Advanced Options.
- Edit the Full name field to your desired display name.
- Click OK and restart your Mac.
Changing Account Name (Short Name) and Home Folder
This process is more advanced and requires caution because it affects your home directory and system references.
Steps involved:
- Create a new administrator account to use during renaming.
- Log out of your current account and log into the new administrator account.
- Rename your user folder in the
/Users/directory to the new name. - Open Users & Groups > Advanced Options and change the Account name and Home directory fields to match the new folder name.
- Restart and log back into your renamed account.
Warning: Improper changes can cause login problems or data loss. Always back up your data before making these changes.
Changing Computer Name on macOS
The computer name on macOS helps identify your Mac on a network. Changing it is straightforward.
- Open System Preferences (or System Settings).
- Click Sharing.
- At the top, you will see Computer Name. Click the field and enter your desired name.
- Close the window; changes take effect immediately.
Summary Table: Windows vs macOS Name Changes
| Type of Name | Windows | macOS |
|---|---|---|
| User Account Name (Display) | Control Panel or Microsoft Account online | System Preferences > Users & Groups > Advanced Options |
| User Folder / Short Name | Requires new account creation or registry editing | Rename home folder + change account name in Advanced Options |

Additional Tips for Changing Names on Your Computer
- Backup Important Data: Before making significant changes like renaming user folders, always back up your files.

“Changing the user account name or computer name is not just cosmetic. It can affect how software and networks recognize your device and profile.”
Frequently Asked Questions (FAQs)
Q1: Can I change my Windows user folder name without creating a new account?
Technically yes, through registry edits and folder renaming, but it’s not recommended due to the risk of system instability and data loss. Creating a new user account is safer.
Q2: Will changing my Microsoft account name affect my email or other services?
No, changing the display name does not change your actual email address or login credentials, only the name shown in Windows and Microsoft services.
Q3: How do I know if I use a local or Microsoft account on Windows?
Go to Settings > Accounts. If it shows your email address, you use a Microsoft account; if it shows a username without email, it’s a local account.
Q4: Can I change my Mac’s computer name remotely?
Yes, if you have remote access and appropriate permissions, you can change it either via System Preferences or command line using Terminal.
Q5: Will changing my computer name disconnect me from the network?
It may temporarily disconnect you from some network shares or services until the network recognizes the new name, but reconnecting is usually straightforward.

Changing your name on your computer—whether it’s your user account name or the device’s computer name—is a useful way to personalize your setup or organize devices on a network. The process varies depending on your operating system and whether you use local or online accounts.
Windows users should be aware of the differences between local and Microsoft accounts, while macOS users should exercise caution when renaming home folders. Always back up data before making system changes, and follow the steps carefully to avoid issues.
