SUMMARY

Windows NT security makes it possible to lock down a desktop so a given user has access to only one or a few specific programs. On a public kiosk computer, it is often important that user access be restricted. This article explains the steps that need to be taken to implement this.
  1. Create a text file named Lockout.reg. You can cut and paste the following text:

    REGEDIT4

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies]

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] "NoDriveTypeAutoRun"=dword:00000095
    "NoFind"=dword:00000001
    "NoFolderOptions"=dword:00000001
    "NoFavoritesMenu"=dword:00000001
    "NoRecentDocsMenu"=dword:00000001
    "NoSetActiveDesktop"=dword:00000001
    "NoDesktop"=dword:00000001
    "NoSetFolders"=dword:00000001
    "NoSetTaskbar"=dword:00000001
    "NoSaveSettings"=dword:00000001
    "NoClose"=dword:00000001
    "NoNetHood"=dword:00000001
    "NoRun"=dword:00000001
    "NoDrives"=dword:00000000
    "NoTrayContextMenu"=dword:00000001
    "NoViewContextMenu"=dword:00000001

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System] "DisableLockWorkstation"=dword:00000001
    "DisableTaskMgr"=dword:00000001
    "DisableChangePassword"=dword:00000001
  2. Determine what drives you want the user to be able to access, and then change the value of the "NoDrives" line accordingly. For example:

    To give access to only drive C -> "NoDrives"=dword:fbffff03
    To give access to drives C and D -> "NoDrives"=dword:f3ffff03
    To give access to drives A to F -> "NoDrives"=dword:c0ffff03
  3. Determine if you want a compact disc to start automatically when you place it in the CD-ROM drive. If you do not want this to happen, change the "NoDriveTypeAutoRun" to:

    "NoDriveTypeAutoRun"=dword:b5000000
  4. Determine if you want to enable the user to log off or to shut down the computer. You can disable these by adding one or both of these two lines:

    "NoClose"=dword:00000001
    "NoLogoff"=dword:00000001
  5. Create a new user with User Manager. Set up the menu structure that you want the user to see. This can be done by adding and removing short cuts from the Windows NT\Profiles\%USERNAME% and the Windows NT\Profiles\All Users folders. For example:

    C:\WINNT\Profiles\NewUser and C:\WINNT\Profiles\All Users.
  6. Log on as the new user and set up the environment (screen savers, background, and so on).
  7. Find the file you created in the steps above and double-click it.
  8. Log back on as the user. You will notice that the desktop is empty and the start menu only has the shortcuts that you configured in step 4. As stated in article 182439 "How to Disable Start\Help," it is impossible to remove the help item from the start menu. You can disable this by creating a text file named Windows.hlp and copying it over the existing file in the Windows NT\System32 folder.
