Hello, my name is Emmanuel, and I am an independent advisor. I'll be more than happy to assist you today!
I am so sorry to hear that you are having an issue changing the name on your computer's lock screen. I recommend following the steps below:
- Kindly press the Windows logo key + R on your keyboard.
- Type in the word “netplwiz” (without quotes) and then press the enter key. This will open the “User Accounts” window.
- In the User Accounts window, select the user that you want to change the name of and then click Properties.
- Under the General tab, type your desired name in the Full Name field.
- Click Apply and Okay.
- Your computer will require you to sign out of your user account and sign back in. On the sign-in screen, you will see that your name on the lock screen has been changed to your preferred one.
I hope this information can help you.
Let me know if this works for you.
I hope you are happy and satisfied with how I assisted you today.
Have a nice day and keep safe!
