Dear Ahnahita,
Hello! Welcome to the Microsoft Community. I'm glad to be able to help you. If I don't understand your question, please let me know immediately.
I understand that someone with your computer password entered your computer without your consent, and then it seems that a user was created. At present, you should need to open local users and groups to view and operate it. But local users and groups cannot be found in your PC. I understand the trouble this problem has caused you, and I will try my best to help you solve it.
- Check the Windows version
Windows 11 Home Edition: There is no local users and groups feature in Windows 11 Home Edition. It is only available in Professional, Enterprise, and Education editions. You can try to install it in Home Edition:
Add local users and groups through Microsoft Management Console (MMC):
- On the desktop, press WIN + R to open the Run window.
- In the Run window, enter the "mmc" command and press Enter.
- In the opened MMC window, click the "File" menu and select "Add/Remove Snap-in".
- In the pop-up window, select "Local Users and Groups" and click the "Add" button.
- Select "Local Computer" and click "OK". In this way, you can see local users and groups in Computer Management.
- Access Local Users and Groups through Computer Management
If you are using a compatible edition (Pro, Enterprise, or Education) and still don't see it:
-Right-click the Start menu and select Computer Management.
-In the left sidebar, try to expand Local Users and Groups. If it doesn't appear, continue with the next steps.
- Group Policy Editor (for Pro or higher)
If you are using a higher edition but still want to manage users through the GUI:
-Press Win + R, type gpedit.msc, and press Enter.
-Navigate to Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment.
By following these steps, you should be able to determine why Local Users and Groups is not appearing in Computer Management and take appropriate action. If you are using Windows 11 Home, consider upgrading to Pro to access this feature.
Hope these steps can help you. If you have any questions, please let me know in time.
Best Wishes
