Using Registry Editor (for editions of Windows that don't include the security policy editor)

Locate 'Interactive logon: Do not display last user name' policy.

When the Local Security Policy editor loads, navigate through Local Policy and then Security Options.Click on the Start Button, type in secpol.msc and hit Enter.There are two ways to turn on the setting that will remove the user list and present a simple username and password box shown above. It is for these reasons that I highly reccomend what is common practice in any large enterprise, and hide the remove the user list from the logon screen. The attacker just needs to find your computer's IP address and then start to brute force your password. In addition, if Remote Desktop is enabled, an attacker can remotely identify the user currently logged in as it is listed on the logon screen. This can be a security risk as it provides useful information to a malicious user attempting to breach your computer.

Every time you boot up your PC all computer accounts are normally displayed right on the logon screen.
