Some Useful Registry Tips




The registry settings are:
  1. HKEY_LOCAL_MACHINE\Microsoft\Windows NT\CurrentVersion\Winlogon
    (Windows 2000 Professional)

    The GINADLL value is set for either a Microsoft logon screen or a Novell login screen. If you want to use a Novell login screen, make sure that the value is NWGINA.DLL. If you want to use a Microsoft Login screen, make sure the value is MSGINA.DLL. Then close the Registry Editor and restart the system.
  2. HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\
    Policies\Explorer\NoClose

    This String Value set to 1 removes the Shutdown option from the Startmenu. Change it to 0 to allow shutdowns.
  3. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\
    Winlogon\PasswordExpiryWarning

    This key in Windows 2000 sets the number of days before a user's password must be changed.
  4. HKEY_CURRENT_USER\RemoteAccess\Addresses

    This key is where the Dial-Up Networking settings are stored.
  5. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\
    i8042prt\Parameters\CrashOnCtrlScroll

    Set thisDWORD value to 1. After a reboot, hold down the right CTRL key and hit the Scroll Lock key twice. This generates a BSOD. This is intentional as it can be used for testing purposes.
  6. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
    Policies\Explorer

    Change (or create) the NoFileMenu value to 1 to hide the File menu, or 0 to show it.
  7. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
    WindowsUpdate\Critical Update\CurrentDelayInterval

    This REG_DWORD value is the value in seconds between prompts from the Critical Update Notification. The default is 86,400 seconds (1 day).
  8. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom

    Changing this value to 1 disables the CD-ROM autorun feature.
  9. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
    Policies\Ratings

    If you are using the Content Advisor in Internet Explorer and have forgoteten the password, you can delete this key and reset all of the ratings and delete the password.
  10. HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\
    Window_placement

    Deleting this value will reset the size of the IE Window.
  11. HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
    HKEY_CLASSES_ROOT\Directory\shellex\ContextMenuHandlers
    HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers
    HKEY_CLASSES_ROOT\Drive\shellex\ContextMenuHandlers

    These 4 keys are where the Righ-Click menu options are stored for folders, directories, and drives. To remove a right-click context menu item, you could delete any of the sub-keys that are below these keys.
  12. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\
    Explorer\RemoteComputer\NameSpace\{D6277990-4C6A-11CF-8D87-00AA0060F5BF}
    (Win2000)

    This key instructs Windows Explorer to search for Scheduled Tasks when you are trying to connect to a remote computer. To browse Windows 2000 and 98 computers faster, delete the key.
  13. HKEY_CLASSES_ROOT\Unknown\Shell

    To add a righ-click context menu item to an unknown file type, right-click on the Shell subkey and choose New - Key. This will add a new subkey below the Shell. Give the new subkey the name of the application as you'd like it displayed on the context menu.
    Next, you'll need to create another new subkey under your newly created application subkey called command. There will be a Default value automatically created. Double click this value and enter the full path of the application's executable file, but append a %1 to the end (i.e. c:\winnt\notepad.exe %1).
    The next time you right-click on that unknown file extension, you should see your new menu item.
  14. HKEY_CLASSES_ROOT\CLSID\
    {20D04FE0-3AEA-1069-A2D8-08002B30309D\LocalizedString
    (Win2000)

    From this value you can change the name of the My Computer icon. The default value is:
    @D:\WINNT\system32\shell32.dll,-9216@1033,My Computer
    As you can see, the name is the last part after the , and you can change this to whatever you want. A neat trick is to change the My Computer part to %computername% and that will name My Computer the name that your computer has in the Network settings. If you do this it should look like this:
    @C:\WINNT\system32\shell32.dll,-9216@1033,%computername%
  15. HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Outlook\
    Preferences\LocationMRU

    This key contains the most recent entered locations for meetings and appointmenst in Outlook 2000. You can't edit any of these, but you can delete then entire value.
  16. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
    Explorer\Tips

    There are 50 tips stored in this key. You can double-click on any of them to edit the tips.
  17. HKEY_USERS\.DEFAULT\Control Panel\Keyboard\InitialKeyboardIndicators
    (WinNT/2000)

    This REG_SZ or String value when set to 2 will make the NUMLOCK turn on when Windows loads. A value of 0 will turn the numlock off.
    This will make the change for all users. If you want to do it for an individual user, then change the same value in the HKEY_CURRENT_USER hive.
  18. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\PowerdownAfterShutdown
    (WinNT/2000)

    This REG_SZ or String value when set to 1 will automatically power off your computer if the BIOS supports this. A value of 0 will leave you at the "It is now safe..." screen.
  19. HKEY_CURRENT_USER\ControlPanel\Desktop\PaintDesktopVersion

    In Windows 2000, a DWORD value of 1 will display the Windows version on the desktop. A value of 0 does not display it.
  20. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
    CurrentVersion\ Setup\SourcePath

    This REG_SZ or String Value key stores the path to the location of the installation files.
  21. HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt

    These are menu items that appear in the Right-Click menu of Internet Explorer
  22. HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Extensions HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Extensions

    Each subkey of these keys define an addition to IE's Tools menu
  23. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
    Policies\ActiveDesktop\NoChangingWallpaper

    This DWORD value 1 will stop people from being able to change their desktop wallpaper. A value of 0 will allow users to change the wallpaper.
  24. HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\TypedURLs
    (Win9x)
    HKEY_USERS\S-1-5-21...\Software\Microsoft\Internet Explorer\TypedURLs
    (WinNT/2000)

    When you type a URL in Internet Explorer (IE), the system automatically completes known entries with data stored in this registry key. Each time you type in a URL and press the Enter key or the Go button, that URL is stored in this location.
  25. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
    Policies\Explorer\NoLogOff

    This DWORD value set to 1 will remove the "Log Off User" option in the Start Menu. A value of 0 will show it.
  26. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
    Policies\System\NoDispBackgroundPage

    This DWord value set to 1 will stop the Background page of the Display applet from appearing. Setting it to 0 will cause it to appear.
  27. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
    Explorer\Advanced\StartMenuScollPrograms

    This String entry in the registry can be created if it doesn't exist. If you set it to FALSE it will make the start menu run into multiple columns. This works with IE5. You have probably noticed that if your Start Menu is too long, you get a little arrow at the top or bottom of the Programs menu telling you that you need to scroll to see what else is there. You can change this to behave the way Windows 95 used to.
  28. HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\
    Toolbar\BrandBitmap
    HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\
    Toolbar\SmBitmap

    If you downloaded IE from ZDNet, Tucows, or any other major site, it is probably "branded", meaning that it probably has its own logo in the upper-right corner and in the title bar it says the branded name. These 2 registry settings should be deleted if you want to remove the branded logo. This will set it back to the default IE globe.
  29. HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\
    Main\Window Title

    This is where you can change the browser name that appears in the Internet Explorer window title. You can change it to anything you want.
  30. HKEY_CURRENT_USER\Software\Microsoft\Office\8.0\Word\
    Options\LiveScrolling

    This features allows you to have smooth scrolling in Word 97. When you use the scroll bars in Word 97, you can't see the document as it scrolls by until you let go of the scroll bar. Adding this LiveScrolling setting and setting it to 1 will allow you to see document scroll by.
  31. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
    Eexplorer\Desktop\NameSpace

    A lot of programs install themselves and add an icon to the desktop. The problem is, this isn't just a shortcut that can be deleted. These are permanent links to certain programs/features. In order to delete them, you need to navigate to this registry key and delete any entries you do not want.
  32. HKEY_CURRENT_USER\Controal Panel\Desktop\MenuShowDelay

    This resgitry entry will control how fast each menu sub-level appears and how fast the taskbar will appear if you have autohide set up. The number that you enter will be the time in miliseconds the operating system will pause. 1 second would need an entry of 1000. I usually set mine at 0 so that it appears as quick as it can.
  33. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
    Explorer\MenuOrder

    This registry key is where you would go in Windows 98 and Windows 95 with the windows update installed to fix your menu order. Maybe you haven't noticed, but the menu items in the Start Menu and in the Favorites folder don't have to be in alphabetical order. By dragging them, you can put them in any order you want. The problem is, once you have changed one, you can never get it back to alphabetical order without fixing it in the registry.
    From the MenuOrder key, choose which sub key you want to edit, the Start Menu or the Favorites. You will see more sub keys that are called Menu. You can either delete that key, or delete the binary Order listing in the right hand pane. You can search through all of the sub keys for the same thing and reset any of them that you want.
    If you don't like working in the registry, there is a PC Magazine utility available called MenuZap that you can download which does all of this automatically for you. Visit http://www.zdnet.com/pcmag/ and do a search for MenuZap to find it.
  34. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
    Uninstall

    This registry key contains all of the sub keys for programs that can be uninstalled. When you want to uninstall, always use the uninstall program that came with the program or use the Add/Remove Programs applet of the Control Panel. This registry key can be useful when you have done that, but the program still comes up in the Add/Remove Programs listing. When you click on it it says "Can't find this file." Well, of course it can't, it has been uninstalled. It is just that the registry listing hasn't been removed.
    To remove it, just visit this key, and then scroll down until you see the culprit. You might have to click on the sub key once so that the real name shows up in the right hand pane. Sometimes the sub key names don't make a lot of sense.
  35. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion

    This registry key will allow you to change to information you inputted about who Windows was registered to. You can change the company, persons name, the registration key, etc.
  36. HKEY_CURRENT_USER\Software\Microsoft\MS Setup (ACME)\User Info

    Have you noticed that when you install programs, it quite often automatically knows your name and your company name? That information does not come from the registry key mentioned above this one. It is found in this one. If you have gotten a used computer from someone or have changed companies and want to change those names, then visit this key.
  37. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

    This registry key will help you when there are programs starting up that you don't want running. When you install something like Norton Utilities or an antiviral program, they load up at start up and put a small icon in the system tray. You probably want most of these programs running, but lets say that you don't want it running. How do you get rid of it. There should be an option in the program setup, but if you just can't find it, you can go to this key, or any other that starts with RUN and delete the listing in the right hand pane.
    For instance, Power Management is installed by default by Windows, even if you go into the power settings and tell it you want the computer on all the time, there is still a line in the RunServices key. It wasn't doing any harm because the power profile was set so that everything was on all the time, but why even have the profile in there is I don't use it. So I deleted it.
