NOTE: Please use this carefully when hiding a user account from the Welcome Screen, or you may lock out yourself from accessing the system.
1. Click Start, type REGEDIT into Search bar and press Enter. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
3. Right click Winlogon in the left pane, click Export, select Desktop in the Save in box and type Backup (without the quote) in File Name, then click Save.
Note: The backup file is on the Desktop and named as Backup.reg. We can simply restore the registry by double-clicking the backup.reg file. Once we have completed the troubleshooting and the issue has been resolved we may delete that file.
4. Right click on Winlogon on the left pane, click New -> Key
5. Name the key as SpecialAccounts
6. Right click on SpecialAccounts on the left pane, click New -> Key
7. Name the key as UserList
8. Right click on UserList on the left pane, click New -> DWORD (32-bit) value.
9. The value name is the exact username that you want to hide.
For example, if you would like to hide the user account "Owner" from the Welcome Screen, the value name for this key is Owner
10. The numerical value is a 0 or a 1. If you set it to 0, then the account will be hidden. Set it to 1, and it will be shown.
