Hi, I am Van. I'll be glad to assist you today.
If may I ask, are you referring to the built-in Administrator account? If yes, you can do so by performing the steps below.
- Log in to your account that has admin privilege.
- Click the start menu, then type CMD. Right-click the command prompt then select run as administrator.
- Type or copy-paste the command below then press enter.
net user Administrator /active:no
This command will disable the built-in Administrator and will not be visible on the PC.
Best regards,
Van
