Changing your username in Windows 10 or Windows 11 is not as obvious as adjusting the brightness or choosing a WiFi network, but it is not a mission for hackers in black hoodies either. The right path depends on one detail you should check before touching anything: whether you use a Microsoft account, a local account, or a profile managed by a company or educational institution.
To clear that up, open Settings, go to Accounts, and then Your info. If you see an email address at the top, you are using a Microsoft account; if it says Local account, the change is made directly on the computer. That small distinction is what saves you from wandering through menus as if Windows had hidden the setting inside an Easter egg.
Change the name if you use a Microsoft account
When your Windows sign-in is linked to a Microsoft account, the name is not changed directly from a quick system field, but from the account’s own page. In Windows 11, you can open Settings with the Windows + I shortcut, go to Accounts, open Your info, and look for the option related to managing your accounts.
When you click it, Windows will open the browser and take you to Microsoft’s web environment. In most cases, you will already be signed in, although if you are not, you will need to log in with your email address and password. Once inside, look for the Edit name option next to the account’s full name. Microsoft will ask you to enter a first name and a last name; they do not have to match your real name, but both fields must contain something.

It is worth being careful here if that same account is associated with Outlook. The name you enter may also be linked to emails sent from that account, so it may not be the best place to try out an overly creative alias if you use it in a professional context. After saving the changes, Windows will display the new name, although Microsoft says it can take up to 24 hours to appear updated.
Change the name of a local account
If the PC uses a local account, the process is more traditional and goes through Control Panel, that Windows veteran that still appears exactly when you need it. You can open it by typing Control Panel into the taskbar search and selecting the corresponding result from the Start menu.
Inside Control Panel, go to User Accounts. If the view is organized by categories, you will first need to open User Accounts and then repeat the entry with the same name. From there, select Change your account name. Windows may ask for administrator approval to continue; if your user already has those permissions, you can proceed, and if not, you will need the password of whoever administers the computer.
The final step is to type the new account name and confirm with Change Name. In this case, the setting applies to the computer itself, without depending on Microsoft’s website or external synchronization. It is a more direct solution, although also one that is limited to the device where the change is made.
What happens with work or school accounts
Company, university, or school accounts follow different rules. The system may allow you to change the name from Microsoft’s account page, but that option may also be blocked by the organization. In that scenario, the user has no real room to modify the information on their own and will need to contact the IT department or the person responsible for managing those profiles.

The difference is not trivial: with a personal account, you decide; with a managed account, the organization’s policy takes precedence. Does it make sense that you cannot change something as seemingly simple as your display name? From the user’s perspective, it may feel excessive, but in shared environments it helps keep identities consistent and prevents every profile from turning into a collection of nicknames worthy of a 2005 LAN party.
In short, the quickest way to get it right is to identify the account type first. Microsoft account: Settings, Accounts, Your info, and management through Microsoft’s website. Local account: Control Panel and User Accounts. Work or school account: it will depend on the permissions defined by the organization. With that distinction clear, the change stops being confusing and becomes a fairly manageable setting.
