Changing a Windows 10 username works one way for local accounts and another for Microsoft accounts — and the two methods aren’t interchangeable.
Trying to change your Windows 10 username through the wrong method wastes time every time. Understanding how to edit username in Windows 10 starts with one crucial question: do you use a local account or a Microsoft account? Local accounts let you rename directly through Control Panel, while Microsoft accounts require a trip to the Microsoft account website. Picking the right path from the start turns a two-minute edit into exactly that.
Which Account Type Do You Have?
A local account exists only on your PC — it has a username and password that Windows manages entirely on your machine. A Microsoft account connects your Windows login to Microsoft’s online services like OneDrive, Outlook, and the Microsoft Store. Check yours by opening Settings > Accounts > Your info. If you see an email address listed under your name, you’re on a Microsoft account.
Changing a Local Account Username
Local account usernames can be changed directly on your Windows 10 device through Control Panel’s User Accounts section. No internet connection is needed, and the new name appears after you sign out and sign back in.
- Open Control Panel — search for it from the Start menu if you don’t have it pinned.
- Select User Accounts, then User Accounts again.
- Click Change your account name. If you’re changing a different user’s name, choose Manage another account first.
- Type the new name and click Change Name.
- Sign out of Windows and sign back in. The updated name now appears on the lock screen, Start menu, and account panels.
The after signing back in, your new name shows in the top-right of the Start menu and in Settings > Accounts > Your info.
Changing a Microsoft Account Username
You cannot rename a Microsoft account directly inside Windows. The change must be made on Microsoft’s website, and it then syncs back to your PC — a process that can take time.
- Sign in to Microsoft’s account management page with your Microsoft account credentials.
- Select Your info at the top of the page, then choose Edit name under the profile section.
- Enter your new first and last name, complete the CAPTCHA characters shown, and click Save.
- Allow up to 24 hours for the change to appear consistently across all Microsoft services and on your Windows device.
After saving online, sign out of Windows and sign back in to trigger the sync. The name on your lock screen and Start menu may update quickly, but other services like OneDrive or Outlook can take the full window.
Editing Your Windows 10 Username: What Changes and What Doesn’t
The display name — what you see on the sign-in screen, Start menu, and in account panels — updates after a rename. The user profile folder under C:\Users does not change, regardless of which method you use. Microsoft designed it this way because renaming the profile folder can break installed applications, registered settings, and system paths that point to the original folder location.
| Factor | Local Account | Microsoft Account |
|---|---|---|
| Where you change it | Control Panel on your PC | Microsoft account website |
| Internet connection required? | No | Yes |
| Admin rights needed? | Yes | Only to sign in on the PC |
| Changes the profile folder? | No | No |
| How fast it updates | After sign-out and sign-in | Up to 24 hours |
| Works on Windows 10 Home? | Yes | Yes |
| Can Windows rename it directly? | Yes | No — must use website |
Common Pitfalls to Avoid
Most username-change headaches come from a handful of easily avoidable mistakes — confusing the sign-in name with the profile folder, renaming a Microsoft account locally, or expecting the change to appear everywhere instantly. The table below maps each pitfall to the fix.
| Pitfall | What Actually Happens | How to Avoid It |
|---|---|---|
| Profile folder stays C:\Users\[oldname] | Apps may break if you rename the folder manually | Leave the folder name as-is — only the display name changes |
| Renaming Microsoft account only in Windows | The change reverts or never sticks | Always change Microsoft accounts on Microsoft’s website |
| Expecting instant updates on Microsoft accounts | Old name lingers on some services for hours | Allow the full 24-hour sync window |
| Using lusrmgr.msc on Windows 10 Home | The Local Users and Groups snap-in does not exist | Use Control Panel’s User Accounts instead |
| Changing a work or school account locally | Those accounts sync from your organization’s directory | Contact your IT administrator for a rename |
| Not signing out after a local change | Old name still shows on the lock screen | Sign out of Windows and sign back in |
| Using the wrong method for your account type | Steps don’t match what you see on screen | Confirm your account type in Settings > Accounts > Your info first |
Quick Reference: Pick Your Path
Start by opening Settings > Accounts > Your info and noting whether an email address appears. For a local account, use Control Panel > User Accounts > Change your account name, enter the new name, sign out, and sign back in. For a Microsoft account, visit account.microsoft.com/profile, edit your name there, complete the CAPTCHA, save, and allow up to 24 hours for the sync. In both cases the profile folder under C:\Users stays unchanged — leave it alone and the rename is complete.
