Windows 10 and Windows 11: The Settings Route

The fastest way to change your username on an Acer laptop running Windows 10 or 11 is through Settings. Open Settings by pressing the Windows key and typing "Settings," then select the Settings app. Go to Accounts in the left sidebar, then click Your info at the top.

You'll see your current username displayed under "Your info." Click the Rename your device button. A dialog box will appear asking for a new name — this is your device name, which is what appears on your network. Type your new name and click Next, then Finish. Your laptop will ask you to restart; do that to explore the change.

This method changes the name your laptop shows on a network or when you share files. It does not change your user account name — the folder name in C:\Users\ or the name that appears on your login screen. If you need to change that instead, use the Local Users and Groups method below.

Key Takeaways

  • The Settings app method changes your device name (what appears on networks), not your login account name.
  • To change your actual user account name, you must use Local Users and Groups (Windows Pro or higher) or create a new account and transfer files.
  • Changing your account name requires administrator rights; if you do not have them, ask whoever set up the laptop.
  • Your device name change takes effect after a restart, but account name changes may require you to log out and back in.
  • If you forget your password during this process, you will need a password reset disk or another administrator account to regain access.

Changing Your User Account Name in Local Users and Groups

If you need to change the actual user account name (the one that appears on your login screen and in your user folder), you need access to Local Users and Groups. This tool is available only on Windows Pro, Enterprise, or Education editions — not on Windows Home.

Press the Windows key and type "lusrmgr.msc," then press Enter. If you see a User Account Control prompt, click Yes. In the window that opens, click Users in the left sidebar. You'll see a list of all user accounts on your laptop. Right-click your account name and select Rename. Type your new name and press Enter.

Log out of your account completely, then log back in. Your new account name is now active. The folder in C:\Users\ will still have the old name, but Windows will recognize your account by the new name you entered.

If You Have Windows Home Edition

Windows Home does not include Local Users and Groups, so you cannot rename your account directly. Your options are to change your device name (using the Settings method above) or to create a new user account with the name you want.

To create a new account, open Settings, go to Accounts, then click Other people (or Family & other people in some versions). Click Add account and follow the prompts to create a new local account. Once the new account exists, you can transfer your files from the old account to the new one by copying them from C:\Users\[old name] to C:\Users\[new name].

After you've moved your files, you can delete the old account. Go back to Settings, select the old account under Other people, and click Delete. Windows will ask whether to keep or delete the account's files; choose based on whether you've already moved everything you need.

What Happens to Your Files and Passwords

Changing your device name does not affect your files or passwords at all. They stay exactly where they are. Changing your user account name also does not affect your files — Windows keeps track of them by a hidden identifier, not by the name you see.

However, some programs may store settings or shortcuts that reference your old username. After you change your account name, those programs might not find those files. Restarting your laptop usually fixes this, because Windows updates the file paths. If a program still cannot find its settings, uninstall and reinstall it.

Your password does not change when you rename your account. You still log in with the same password you used before. If you want to change your password at the same time, do that separately through Settings > Accounts > Sign-in options > Password.

Changing Your Microsoft Account Display Name

If you log into your Acer laptop with a Microsoft account (rather than a local account), you can change the name that appears on your login screen by editing your Microsoft account profile online. Go to account.microsoft.com and sign in. Click Your info on the left, then click Manage your Microsoft account.

Under your profile picture, you'll see your current name. Click Edit name and type your new first and last name. Click Save. The change takes effect the next time you restart your laptop or sign out and back in.

This method changes only the display name on your Microsoft account — the name that appears on your login screen and in Windows. It does not change your device name or your local user account name if you have one.

Troubleshooting Common Problems

If you see an error saying "The specified user name is already in use," the name you chose already exists on your laptop. Choose a different name. If you see "Access denied," you do not have administrator rights on this account. Ask whoever set up the laptop to make the change, or ask them to give your account administrator rights.

If you changed your account name but some programs still show your old name, restart your laptop. If the problem persists after a restart, those programs may have cached your old username in their settings. Open each program's settings or preferences and look for a field showing your username — you may need to update it manually or reinstall the program.

If you cannot remember your password after changing your account name, you cannot log back in. If you have a password reset disk, use it. If not, you will need another administrator account on the laptop to reset your password, or you will need to contact Acer support or a local computer repair service.

Frequently Asked Questions

Will changing my username affect my Wi-Fi or email?

No. Your Wi-Fi password and email account are separate from your laptop username. Changing your laptop name or account name does not disconnect you from Wi-Fi or change your email login. You may need to re-enter your Wi-Fi password once if your router recognizes devices by name, but your email will work exactly as before.

Can I change my username without restarting?

Device name changes require a restart. Account name changes require you to log out and back in. There is no way to explore either change without one of those steps.

What if I change my account name and then forget my password?

You will not be able to log in. If you have a password reset disk, use it. If you have another administrator account on the laptop, use that account to reset your password through Settings > Accounts > Other people. If neither option is available, you will need external help to regain access.

Does renaming my account affect my files or programs?

Your files stay in place and remain accessible. Most programs continue to work normally. Some programs that store settings based on your username may need to be restarted or reinstalled, but this is rare and usually fixes itself after a restart.

Can I change my username if I do not have administrator rights?

No. You need administrator rights to change either your device name or your account name. If you do not have them, contact the person who set up your laptop and ask them to make the change or grant you administrator rights.
