  1. Logon or login to the Windows computer with any user account.
  2. Navigate to %systemroot%\System32 in Windows Explorer. %systemroot% is your Windows installation folder, and normally located in \WINNT or \Windows (i.e. \WINNT\System32).
  3. Save a copy of LOGON.SCR file, or simply rename the logon.scr file to something else. Just make sure that you remember where and what name is the backup copy.
  4. Delete the original LOGON.SCR from the %systemroot%\System32 sub-folder after you have backed it up. The file should no longer exist if you rename it.

    Note: If you having problem to delete or rename LOGON.SCR, it may be due to permission settings. Try to take ownership of the LOGON.SCR (by right clicking on LOGON.SCR, then select Properties and go to the Security tab, then click on the Ownership. Click “Take Ownership” and then click Yes to the prompt message.), and give the Everyone group Full Control permissions (by right clicking on LOGON.SCR then select Properties, then go to Security tabs. Click on Add and browse to and add the Everyone group. Give Everyone Full Control and then click on OK.) You may need to install an alternate second copy of Windows on the machine to do so as detailed at the end of this article.

    net user administrator newpassword

    And the user account for administrator will have the new password of newpassword (which you should change to your own password). With the syntax of net use user_name new_password, it can be used to reset or modify the password of other administrative user account’s passwords.

  9. You can now log on to the administrator account with the new password. You may want to replace back the original LOGON.SCR that has been backed up or renamed.
  10. You may want to delete the alternate installation of Windows, by deleting the installation folder or format the partition (if you install in different partition), and removing the second Windows entry in BOOT.INI file at the root. Use attrib -r -s -h c:\boot.ini to change and allow the boot.ini to be modified and viewed.
Disable Password Caching

Disable Password Caching

April 25, 2009
As in Windows for Workgroups, when logging on to an NT Domain, it is preferable to disable password caching.
This allows for the single NT Domain login and eliminates the secondary Windows logon screen.
It also eliminates the possibility of the respective passwords to get out of sync.
To disable password caching on the workstation, a one-line addition to the registry needs to be made.
To make the change, create a ASCII text file called DISABLE.REG with the following lines:


  • REGEDIT4 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Network]
    "DisablePwdCaching"=dword:00000001



  • Open up a DOS box and type REGEDIT DISABLE.REG
    You can also download the DISABLE.REG file.
    If you need to re-enable password caching, download ENABLE.REG and repeat the process just with the different file name
