Sometimes it’s the little things you overlook that make life easier. Like renaming your computer. It’s such a simple task but can save hours of frustration when your devices talk to each other on a local network or in a workplace setting. At Nimble Nerds, we’ve helped plenty of clients who struggled with mixed-up device names. It’s not just about vanity – a clear computer name means better organisation and less confusion when sharing files or troubleshooting remotely.

How to Change Computer Name on Windows 10 and 11

Using Settings on Windows 10 or 11

Windows has made it pretty straightforward, but we’ve still had a few people call in after getting tripped up. To rename your PC, hit Windows + I to bring up Settings, or click the Start menu and select Settings. From there, select System and scroll to About, down at the bottom of the menu.

Your current computer name will be listed under Device specifications. There’s a ‘Rename this PC’ button sitting right beside it. Give that a click and a window will pop up. This is where you type in your new machine name – just remember:

No spaces or odd characters (like commas or question marks)
Stick with something simple, unique, and easy to recognise on your network – names like “ReceptionPC” or “Tom-Work” usually do the trick

Once you’ve typed the new name, click Next. The system will prompt you to restart for the change to actually take effect. From our own experience, it’s best not to skip the restart – sometimes quirky things happen if the computer isn’t rebooted right after renaming. [1]

Using System Properties

For those of us who’ve been around Windows a while (or for jobs that need a little more technical attention), the old-school System Properties method still works a treat. The quickest way is to right-click on This PC or Computer, then pick Properties.

In the window that opens, look to the left for Advanced system settings and give that a click
The System Properties box appears; select the Computer Name tab
Click the Change button and type your new name

We often rely on this route when assisting businesses that have more tailored system setups, or if you’re joining devices to a domain. After entering the new name, just hit OK, and you’ll be prompted to restart – again, don’t skip this.

Using Control Panel

If you’re most comfortable in the classic Control Panel, you’re sorted as well. First, open Control Panel, head to System and Security, and click System. On the left, there’s that familiar Advanced system settings link.

Inside the System Properties, go to the Computer Name tab and click Change. Once you put in your new name and press OK, a restart will lock it in.

Change Computer Name on Mac

Renaming your Mac is one of those things that’s easy to overlook, but it’s usually sorted in a few seconds. Click the Apple menu at the top left, then open System Settings (or System Preferences – depends on your version). From there:

In the sidebar, select General, then About
At the top, your current computer name will show up – click it
Type your new name, and you’re all set

There’s no need to restart, which we find throws some people off – they keep waiting for a message or reboot prompt, but the change is instant. It’s a handy little feature that especially helps if you’re working in a shared space or outsourced your IT and want us to find the right computer quickly. [2]

Naming Best Practices and Network Considerations

Naming Conventions

Picking the right name matters more than most people realise. It’s not just a label but a key to smoother communication between devices. Here’s what we recommend:

Use unique names: Make sure your device’s name isn’t the same as another on your network. Duplicate names can cause confusion or connection issues.
Avoid spaces and special characters: Stick with letters, numbers, hyphens, or underscores. Spaces, periods, commas can cause problems in some systems or scripts.
Keep names short and descriptive: Something like “Office-PC” or “JohnsLaptop” is easy to read and remember.

We’ve had clients call us because their file sharing stopped working only to find out two PCs had the same name. A quick rename fixed it.

Network Impact

When you rename your computer, you’re not just changing a label on the screen. The new name is how your device identifies itself on the local network and within workgroup settings or domains.

The computer name shows in network lists, so a clear name helps when you want to share files or connect remotely.
If your device is part of a domain or corporate workgroup, renaming might require updating those settings to keep everything connected properly.
Sometimes, renaming temporarily interrupts your network shares or mapped drives. Usually, these reconnect after a restart, but if you run into issues, re-adding the shares might be necessary.

We always remind business clients to check that their domain or workgroup admins are aware of changes. It saves headaches later.

Verifying and Managing Computer Name

Verification Methods

After renaming, it’s good to double-check your new computer name is set correctly.

On Windows, open Command Prompt (type cmd in Start search), then type hostname and press Enter. It will display your current device name.
Alternatively, check System Properties or the About screen where you first changed the name.

On a Mac, the new name will show in System Settings > General > About. You can also see it in the Sharing preferences pane.

Troubleshooting Common Issues

Some issues pop up when renaming computers, mostly due to permissions or network settings.

You need administrative privileges to rename your device. If you don’t have admin rights, the rename won’t stick or will throw an error.
If you get “permission denied” or rename failures, try running the Settings or Control Panel as an administrator (right-click and select Run as administrator).
Sometimes a renamed PC loses connection to its domain or workgroup. Rebooting often fixes this, but you might need to rejoin the network or ask your IT team to help.

We’ve helped many small business owners who tried renaming without admin rights and got stuck. It’s one of those small things that cause big frustration.

Quick Access Tips

For those who want to speed things up, a few shortcuts help:

Press Windows + Pause/Break to open System Properties directly on Windows. From there, you can click Change to rename your PC.
On Windows 8, the Charms bar (swipe from right or press Windows + C) leads to PC settings, where you can find rename options if you prefer the touch interface.

Simple keyboard shortcuts save time, especially when renaming multiple computers across a business.

FAQ

How do I find where to change my computer name in system settings on Windows?

To change your computer name in Windows, you can start by clicking the system icon or pressing the keyboard shortcut Windows + I to open settings. Then, navigate to System > About where you’ll see your current computer name. From there, click Rename this PC to open a new window where you enter the new computer name. This method is a best practice because it’s quick and shows the current PC name clearly in the system settings.

Can I rename my Mac device using system preferences without restarting?

Yes, on a Mac you can change your computer name through system preferences without needing to restart. Click the Apple menu in the top left corner, then open System Preferences or System Settings. Under General > About, click edit next to the current computer name. After entering the new name, it saves automatically. This method is handy because it avoids interruptions to your workflow and updates the local hostname instantly.

Why should I avoid spaces or special characters when choosing a new computer name?

When you rename your computer, it’s best practice to avoid spaces and special characters like commas or periods in the computer name field. Many operating systems and local network protocols identify devices by their computer name, so using only letters, numbers, hyphens, or underscores avoids issues with domain and workgroup settings. For example, a name like “Office-PC” is less likely to cause connection problems than “Office PC,” which could confuse network devices or cause errors in file sharing.

What happens to my network and workgroup settings after I rename my PC?

Renaming your PC updates the local hostname that identifies your device on the local network and within domain and workgroup settings. After you change your computer name, you might need to reconnect to your workgroup or domain to restore network access. Sometimes file sharing or mapped drives can temporarily disconnect until the computer restarts and the new name propagates through the network. It’s a good idea to check your network settings and ensure your device properly connects after renaming.

Is there a keyboard shortcut or quick way to open system properties for renaming a computer?

Yes. On Windows, pressing Windows + Pause/Break opens the system properties screen directly. From there, you can click the Computer Name tab and hit Change to rename your PC. Alternatively, you can right-click This PC or Computer and select Properties, then access advanced system settings. On Windows 8, the charms bar also provides a route to PC settings where you can change your computer name. These shortcuts save time compared to navigating through multiple dropdown menus or the control panel.

Conclusion

Changing your computer’s name is one of those small but useful tasks that help keep your devices organised, especially when connected to a network.
