Renaming your PC is a straightforward process that takes about five minutes

Your PC's name is the identifier that appears on your network and in file-sharing windows. Windows and Mac both let you change it through their system settings, though the steps differ slightly between the two. You do not need any special software or administrator knowledge—just access to your settings menu and a restart of your computer to make the change take effect.

The name you choose can be anything you want: your own name, a descriptive label like "Home Office," or something more creative. The only real limit is that Windows names cannot exceed 15 characters and cannot contain certain symbols like asterisks or question marks. Mac names have a 63-character limit and are more flexible about what characters you can use.

Key Takeaways

  • In Windows, you rename your PC by opening Settings, navigating to System > About, and clicking the Rename button next to your current PC name.
  • On Mac, you rename your computer by opening System Settings, selecting General, and clicking the Edit button next to the computer name field.
  • After renaming, you must restart your computer for the change to take effect across all your networks and connected devices.
  • Windows PC names cannot contain spaces or special characters like asterisks, but Mac names are more flexible with character choices.
  • If you are on a work network, check with your IT department before renaming your PC, as some organizations lock this setting.

How to rename a Windows PC

Open the Settings app by pressing the Windows key and typing "Settings," then select the Settings app from the results. Once Settings opens, click on System in the left sidebar, then scroll down and click About. You will see your current PC name listed under "Device name."

Click the Rename button next to your current name. A text field will appear where you can type your new name. Type what you want to call your PC, then click Next. Windows will ask you to confirm the restart—click Restart now to explore the change when ready, or Restart later if you want to finish what you are doing first. Your PC will restart and the new name will be active.

How to rename a Mac

Click the Apple menu in the top-left corner of your screen and select System Settings (or System Preferences on older Mac versions). In System Settings, click General in the sidebar, then look for the Computer Name field near the top of the window.

Click the Edit button next to your current computer name. Type your new name in the field that appears, then click Rename. Unlike Windows, Mac does not require an when ready restart, but the change takes effect most reliably after you restart your computer. You can do this by going to Apple menu > Restart, or straightforward restart when you next shut down your Mac.

What happens when you rename your PC

Your PC's name changes everywhere it appears on your network. If you share files with other computers on your home or office network, they will see the new name in their file browser. Any shortcuts or mapped network drives pointing to your old PC name may stop working until you update them to use the new name.

If you use cloud services like OneDrive or iCloud, your PC name change will not affect those accounts—they are tied to your user account, not your computer's name. However, if you have set up remote access to your PC or use it in a work domain, the name change may require you to reconnect or re-authenticate on other devices.

Renaming a PC on a work network

If your PC is connected to a company network or domain, your IT department may have locked the rename function. Attempting to rename it might show an error message saying the setting is managed by your organization. In this case, contact your IT support team—they can rename the PC for you or grant you permission to do it yourself.

Some organizations require specific naming conventions for security and inventory tracking, so changing your PC name without approval can cause problems with network access or software licensing. Always check with your IT department before renaming a work computer.

Choosing a good PC name

Pick a name that is straightforward to recognize and describes the computer's purpose or location. "Home Office," "Living Room," or "Bedroom Laptop" are all clear choices. Avoid names with spaces if you are on Windows—use hyphens or underscores instead, like "Home-Office" or "Home_Office," because some older network tools do not handle spaces well.

Keep the name short and straightforward. Long names are harder to type when you need to connect to your PC from another computer, and they take up more space in network file browsers. Avoid special characters like asterisks, question marks, or forward slashes, as Windows will reject these during the rename process.

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 that account. Log in with an administrator account and try again. On Windows, you can check this by opening Settings > Accounts > Your info and looking for "Administrator" under your account name.

If you are on a work PC and get an error about the setting being managed by your organization, you cannot override this—contact IT. If the rename seemed to work but the old name still appears in some places, restart your PC and check again. Network file browsers sometimes cache the old name and need a restart to refresh.

Frequently Asked Questions

Do I need to restart my computer right after renaming it?

Windows will prompt you to restart when ready after renaming. Mac does not require an when ready restart, but the change works most reliably after you restart. If you skip the restart on Mac, some network features may still show the old name until you restart later.

Will renaming my PC affect my files or passwords?

No. Your files, passwords, and user account remain exactly the same. Only the name your computer uses on the network changes. You will still log in the same way and access all your files normally.

Can I rename my PC back to its original name?

Yes, anytime. Follow the same steps and type your original name or any other name you want. There is no limit to how many times you can rename your PC.

What if I cannot see the Rename button in Windows Settings?

You may not have administrator rights on your account. Log in with an administrator account, or ask someone with admin access to rename the PC for you. If you are on a work network, your IT department may have disabled this feature.

Will renaming my PC disconnect me from Wi-Fi or the internet?

No. Your internet connection is tied to your network adapter and account, not your PC name. You will stay connected to Wi-Fi and the internet after renaming. However, you may need to reconnect to some network printers or shared drives if they were set up using your old PC name.
