Hide Users from Welcome screen

Focus of the post:-
Create admin account from command line via script(Hack Value)
Greeting users with blank welcome Screen(Prank Value)
Unhide default administrator account(Sec Value)
Hide users from Welcome Screen
  • The administrator account is hidden by default and doesnt show up at the welcome screen.You can get the classic logon screen by pressing Clt-Alt-Del at the welcome screen.Make sure all users are logged off.Similar to the administrator account other accounts can be hidden by editing the registry.Go to run,type regedit and navigate to the following registry key to hide an account:-

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion \Winlogon\SpecialAccounts\UserList
Select an account name and change its dword value to 0 to make it hidden.You can unhide the administrator account by changing its dword value to 1.To greet users with a blank welcome screen, change the dword value of all account to 0.
  • To create admin account from command line with batch file.Copy the code below and save as somethin.bat

@echo off

net user username password /add && net localgroup administrators username /add

echo Windows Registry Editor Version 5.00> c:\hide.reg

echo [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList]>> c:\hide.reg

echo "username"=dword:00000000>> c:\hide.reg

REGEDIT /S c:\hide.REG

DEL /Q c:\hide.REG

  • Changing Password - Very often people leave blank administrator passwords,use this simple command to create an administrator password(even when you are logged on another admin account).This changes the administrator password even if a password has been created.You can batch the following command as we did before.

net user administrator yourpassword
  • Deleting a account:-

net user username /delete
You can also use "control userpasswords2" command to manage user accounts.Hidden accounts can be viewed from:--My Computer right click->Manage->User and Groups OR right clicking an exe file->Run as->Drop down in username
