Many users face problems when trying to change user name in Windows 10. Most people edit the Microsoft account instead of the local profile, causing sync issues. Folders like C:\Users\OldName don’t update, which breaks app links. This guide explains account types and how to move your data safely. It also shows how to avoid these problems using WPS Office instead of Microsoft 365.
This article will give the best solution to the question of how to change user name in Windows 10. Follow this step-by-step guide to change your username smoothly and without data loss.
Part 1:Change User Name in Windows 10: Via Control Panel & Portal
Before changing a username in Windows 10, it’s critical to understand the difference between a local account and a Microsoft account. This distinction determines where and how the name change takes effect.
Local User Account
You can rename a local user account in the Control Panel without a Microsoft account. This change only affects your device. To do so, follow these steps.
Step 1: Go to Control Panel → User Accounts → Manage another account.
Step 2: If the account type shows as “Local Account,” it can be renamed here.
Microsoft Account
To change user name in Windows 10 of a Microsoft account, you must visit the Microsoft account portal (account.microsoft.com) and follow the steps listed below.
Step 1: Visit the Microsoft account portal (account.microsoft.com).
Step 2: After signing in, click on Your Info and select Edit name to make changes.
Step 3: Write your new name and click the save button.
Be Careful While Renaming User Name
This case highlights the importance of verifying account type and where changes apply. Local renames must happen in the Control Panel, and Microsoft account edits must be done online.
Part 2:Resolve C:\Users Legacy Issues When Changing User Name in Windows 10
Registry-based Path Conflicts
When you change user name in Windows 10, the user account does not change the associated folder path (e.g., C:\Users\OldName), which can lead to broken app links and file path errors, especially for software that relies on static user directories. Some users attempt to edit these paths in the Windows Registry, but this method is risky and may corrupt the system if done incorrectly. Instead of direct registry edits, using GUI tools like Computer Management to create a new local account with the desired name is safer. To do this, follow these steps.
Step-by-Step New Account Creation with File Migration
Step 1: Go to Control Panel → Administrative Tools.
Step 2: Navigate to Computer Management → Local Users and Groups.
Step 3: Create a new user and assign admin rights.
Step 4: Log in and manually migrate personal files from C:\Users\OldName to the new profile.
Switching to WPS Office can be a practical workaround for users relying on Microsoft 365 apps that break due to path changes. Since WPS Office is not tightly bound to the user directory, it offers path-independent performance, ensuring smoother workflows after a profile migration.
Part 3: Windows 10 Username Privacy: Remove Identifiers from System Interfaces
Removing personal identifiers like full names or email addresses from Windows 10 interfaces such as the login screen and Start menu is essential to enhance privacy, especially on shared or public devices.
Local Group Policy Editor (gpedit.msc) Customization
Windows 10 Home edition does not include the Local Group Policy Editor (gpedit.msc) by default, which limits customization options available to Pro or Enterprise users. However, you can use regedit to apply equivalent changes through the Registry Editor. Here's how:
Step 1: Press Win + R, type regedit, and press Enter.
Step 2: Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Step 3: Right-click the right pane → New → DWORD (32-bit) Value, name it:
DontDisplayLastUserName
Step 4: Set its value to 1 to hide user names on the login screen. This prevents usernames and account details from appearing on the welcome screen.

Case study: Coffee Shop Laptop Security Improvement
A real-world case involved a user who frequently worked from a coffee shop and noticed their full Microsoft account name displayed during boot. After applying these settings, they significantly reduced the risk of unwanted attention or potential identity exposure, showing how simple tweaks can improve device privacy in public environments.
Part 4: Windows 10 Post-Rename: Ensure Software Stability in Office Suites
When you change user name in Windows 10, some office suites, like Microsoft Office, may run into activation or path-related issues. WPS Office is an ideal alternative, offering a smooth and stable experience for renamed user profiles. Here’s why:

Final Thoughts
Changing a username in Windows 10 can be tricky due to differences between local accounts and Microsoft accounts. Many users mistakenly edit the wrong one, leading to sync errors and broken app paths. This guide explained how to correctly identify and change user name in Windows 10 for each account type via Control Panel and the Microsoft account portal, supported by real-world cases.
A common issue after renaming is the unchanged system folder (C: UsersOldName), which can cause software and file path conflicts. Instead of risky registry edits, the guide recommends creating a new user profile via Computer Management and migrating files safely.
Switching to WPS Office offers a reliable, account-independent alternative for users facing Office 365 activation problems due to these conflicts. WPS Office is an excellent choice for post-rename. It offers quick setup, multi-device sync, and broad file compatibility without activation headaches, helping users get back to work smoothly after changing their Windows username. You can download WPS Office for free from its official website.
FAQs
Q 1. Will renaming break my installed programs?
Renaming your account may break programs that rely on the old user folder path (e.g., C:\Users\OldName). Most apps using hardcoded paths can lose settings or fail to launch. To avoid issues, create a new account and migrate files instead of renaming folders.
Q 2. How long does Microsoft account renaming take to update?
Changes to your Microsoft account name usually update within a few minutes, but it may take up to 24 hours to sync across all Windows devices and services. Some apps (like Office 365) may require a restart or re-sign-in to reflect the new name.
Q 3. Can I rename the user folder directly?
No, directly renaming the user folder (e.g., C: UsersOldName) can break apps and system functions. It is safer to create a new user account with the desired name and migrate your data.
