We all know that when you install Windows, you’re asked to create the first user account which is called built-in administrator account. Any other account(s) created using the built-in admin account is/are called user account(s). See this article, if you can’t add users to your Windows OS. Hence, using the built-in account, other accounts can be easily managed and removed, if they’re no longer required. If you’re new to Windows 10, this beginner’s guide will show you how to remove or delete user accounts in Windows 10.

To delete an user account, the necessary condition is that user you want to delete should be logged out. In other words, if there is an user logged in and you want to erase his/her account, this wouldn’t be feasible unless he/she signs out. Also its worth to mention here that you can’t remove built-in admin account, as that account can only be enabled or disabled only.
So here are the ways to remove user account(s) in Windows 10, which are no longer needed.

Hi Kapil. I want to sell an old laptop with Windows 10 installed. How do I remove my account and make it ready for a new owner?
^^ Mike, you can try either of these two options:
1. Perform complete Reset: https://www.kapilarya.com/how-to-completely-reset-windows-10. Note that your Windows license will still tied to the machine.
2. Perform clean install: https://www.kapilarya.com/how-to-make-clean-install-of-windows-10. This will remove your license as well. So the buyer will have to activate Windows themselves.
Hi Kapil. I could see only one account in the settings but when I tried to log in there are multiple accounts with same name. Please help me
^^ Do you see multiple accounts by following FIX 2? Or via LUSRMGR snap-in?
