The quickest way to rename your Windows 11 computer
You can change your PC name in Windows 11 through the Settings app in about two minutes. Open Settings, go to System > About, select "Rename this PC" at the top of the page, type your new name, and restart your computer. The new name takes effect after the restart.
Your PC name is what appears on your network and in file sharing. It's separate from your user account name — changing the PC name doesn't affect your login or any of your files. You'll need administrator rights on your computer to make this change.
Key Takeaways
- The Settings app's About page is the standard way to rename your PC, and it takes effect only after you restart.
- Your new PC name can be up to 63 characters long and cannot contain spaces or most special characters — letters, numbers, and hyphens work.
- The change affects how your computer appears on your home or work network, but does not change your user account name or any files.
- If you cannot find the Rename option in Settings, you may not have administrator rights, and you'll need to contact whoever manages your computer.
Step-by-step: renaming through Settings
Start by opening the Settings app. Press the Windows key and type "settings," then click the Settings icon, or press Windows key + I.
Once Settings opens, click System in the left sidebar, then scroll down and click About. Near the top of the About page, you'll see your current PC name and a button labeled "Rename this PC." Click that button.
A dialog box will appear with a text field containing your current PC name. Delete the old name and type your new one. Click Next, then Restart Now to explore the change when ready, or click Later if you want to restart manually when you're ready. Your computer will restart and the new name will be active.
Rules for your new PC name
Windows 11 has specific rules about what characters you can use. Your PC name can be up to 63 characters long and can include letters (A–Z, a–z), numbers (0–9), and hyphens (-). Spaces, periods, underscores, and most special characters are not allowed.
The name is not case-sensitive — "MyComputer" and "mycomputer" are treated the same way. If you try to use a forbidden character, Windows will show an error message and ask you to choose a different name. Common mistakes are including spaces or using an underscore instead of a hyphen.
What changes and what stays the same
Changing your PC name affects how your computer appears on your network and in shared folders. If you're on a home network or work network, other computers will see the new name when they browse for devices to connect to. File sharing and printer sharing will still work, but the computer will be listed under its new name.
Your user account name, password, and all your files remain unchanged. You'll still log in the same way, and nothing in your Documents, Downloads, or Desktop folders is affected. If you have multiple user accounts on the computer, they all stay as they are.
If the Rename option is grayed out or missing
If you don't see the "Rename this PC" button or it's grayed out, you likely don't have administrator rights on your computer. This is common on work computers or shared devices where an IT department or another user manages permissions.
Contact the person who manages your computer or your IT support team and ask them to rename the PC for you. If this is your personal computer and you're the only user, you may need to check your account type — go to Settings > Accounts > Your Info and look for "Administrator" next to your account name. If it says "Standard user," you'll need to switch to an administrator account or create one.
Renaming a computer on a domain network
If your computer is connected to a work domain (not just a regular home or office network), you may not be able to rename it through Settings. Domain-joined computers are usually managed by IT, and renaming requires administrator approval and sometimes a restart that affects network access.
Contact your IT department before attempting to rename a domain computer. They may have a specific process or may need to make the change themselves. Attempting to rename without permission can cause network connection problems.
Restarting after the rename
Windows 11 requires a restart for the new PC name to take effect. If you click "Restart Now" in the rename dialog, your computer will restart when ready — save any open work first. If you click "Later," the new name won't be active until you manually restart your computer.
After the restart, you can verify the change by opening Settings > System > About again and checking that your new name appears at the top of the page. On your network, the computer may take a few minutes to appear under the new name on other devices.
Frequently Asked Questions
Will changing my PC name affect my files or programs?
No. Your files, programs, and user account remain unchanged. Only the name your computer uses on the network changes. You'll still log in the same way and access everything as before.
Can I change my PC name without restarting?
No. Windows 11 requires a restart for the new name to take effect. You can delay the restart by clicking "Later," but the change won't be active until you restart.
What if I want to change my user account name instead?
That's a different process. Go to Settings > Accounts > Your Info and click "Rename your account." That changes only your login name, not your PC name. Both can be changed independently.
Can I use spaces or special characters in my PC name?
No. Windows only allows letters, numbers, and hyphens. Spaces, periods, underscores, and symbols will cause an error. If you want to separate words, use hyphens instead — for example, "my-computer" instead of "my computer."
How long does it take for the new name to show up on my network?
The name is active when ready after restart on your computer, but other devices on your network may take a few minutes to recognize the change. If a device still shows the old name, restart that device or wait a few minutes and refresh its network browser.
