Change Your PC Name Through Settings

The fastest way to rename your PC is through the Settings app. Open Settings, go to System, then select About. You will see your current PC name listed under "Device name". Click the Rename this PC button, type your new name, and click Next. Windows will ask you to restart your computer — do that, and the change takes effect.

The new name can be up to 63 characters long and can include letters, numbers, and hyphens. Avoid special characters like @, #, or spaces, as they can cause problems with network connections and file sharing. Once you restart, your PC will use the new name on your home network and in Windows.

Key Takeaways

  • The Settings app method (System > About > Rename this PC) is the simplest route and requires only a restart.
  • Your PC name can be up to 63 characters and should contain only letters, numbers, and hyphens.
  • A restart is required for the name change to take effect on your network and in Windows.
  • If Settings does not work, you can rename your PC through System Properties by right-clicking "This PC" and selecting Properties, then clicking "Change settings".
  • Other devices on your network may take a few minutes to recognize the new name.

Rename Your PC Using System Properties

If the Settings method does not work or you prefer the older interface, you can rename your PC through System Properties. Right-click This PC on your desktop or in File Explorer, then select Properties. Look for the "Device name" section and click Change settings or Advanced system settings on the left side.

A window titled "System Properties" will open with the Computer Name tab already selected. Click the Change button, type your new PC name in the field, and click OK. Windows will prompt you to restart. After you restart, the new name is active.

What Happens After You Rename Your PC

Once your PC restarts with the new name, Windows updates your computer's identity on your home network. Other devices — like printers, phones, or other computers — may take a few minutes to recognize the new name. If you have file sharing turned on, other computers will see the updated name when they browse your network.

If you use cloud services like OneDrive or Microsoft 365, the new PC name will appear in your account settings the next time you sign in. Your files and accounts are not affected by the name change — only the label that identifies your computer changes.

Choosing a New PC Name

Pick a name that is straightforward to remember and describes the computer or its location. Common choices include "Sarah-Laptop", "Home-Desktop", or "Office-PC". Avoid names that are too long or contain spaces, as they can cause issues when connecting to networks or accessing shared files.

If you have multiple computers at home, naming them clearly helps you identify which one you are connecting to when you share files or printers. For example, "Living-Room-PC" and "Bedroom-Laptop" make it obvious which device is which.

Troubleshooting a Failed Rename

If you see an error message when trying to rename your PC, the most common cause is that you do not have administrator rights on your account. Log in with an administrator account and try again. If you are already an administrator, restart your computer and attempt the rename once more.

Another reason the rename might fail is if your PC name conflicts with another device on your network. Choose a different name and try again. If Settings keeps crashing when you try to rename, use the System Properties method instead — it is more stable on older Windows versions.

Renaming Your PC on a Work Network

If your PC is connected to a work network or domain, you may not have permission to rename it yourself. Your IT department controls the name for security and inventory reasons. Contact your IT support team and request a name change — they will handle it remotely or provide you with instructions.

Attempting to rename a domain-connected PC without permission can cause network connection problems and lock you out of shared files and printers. Always check with your IT team first if you are unsure whether your PC is on a domain.

Frequently Asked Questions

Will renaming my PC affect my files or programs?

No. Renaming your PC changes only the label that identifies it on your network. Your files, programs, and user accounts remain exactly as they are. You will not lose anything or need to reinstall software.

Can I rename my PC without restarting?

Windows requires a restart to explore the name change across all systems. You can type the new name and click Next, but the restart is mandatory before the change takes effect on your network.

What if I want to change my username instead of my PC name?

Your username and PC name are separate. To change your username, go to Settings > Accounts > Your info and click "Rename your account". This changes only your login name, not your computer's network name.

How long does it take for other devices to see the new PC name?

Most devices recognize the new name within a few minutes of your restart. Printers and network storage devices may take up to 10 minutes. If a device still shows the old name after 15 minutes, restart that device as well.

Can I use special characters or spaces in my PC name?

Windows will not accept spaces or special characters like @, #, $, or %. Stick to letters, numbers, and hyphens. This prevents connection problems with printers, file sharing, and other network devices.
