If the value of this entry is 1, Program Manager does not begin loading the desktop until the logon script has finished running. If the value is 0, the logon script and Program Manager can run simultaneously. Note: This value entry also appears in HKEY_LOCAL_MACHINE\Software\Microsoft \Windows NT\CurrentVersion\Winlogon. The HKEY_LOCAL_MACHINE value applies to all users. The HKEY_CURRENT_USER value applies only to the current user. You can use the System Policy Editor to change this value. @#$Key 2 Parse Autoexec.bat HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\ParseAutoexec ParseAutoexec REG_SZ Range: 0 or 1 Default: 1 If the value is set to 1, Autoexec.bat is parsed when you log on to Windows NT. If the value is set to 0, Autoexec.bat is not parsed. This has no effect on the parsing of Autoexec.nt or Config.nt. Note: You can use the System Policy Editor to change this value. @#$Key 2 Restricts access to the CDs in the CD-ROM drives HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\AllocateCDRoms AllocateCDRoms REG_SZ Range:1 Restricts access to the CDs in the CD-ROM drives only to the user currently logged on to the computer. In this mode, CDs are allocated to the user as part of the interactive logon process, and freed for general use or for reallocation only when that user logs off. Satisfies part of C2 security requirement that removable media must be able to be secured. If this value entry is not added, the contents of the CDs in the drives will be available to all processes on the system. @#$Key 2 Restricts access to the disks in the floppy disk drives HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\AllocateFloppies AllocateFloppies REG_SZ Range:1 Restricts access to the disks in the floppy disk drives only to the user currently logged on to the computer. In this mode, floppy disks are allocated to the user as part of the interactive logon process, and freed for general use or for reallocation only when that user logs off. Satisfies part of C2 security requirement that removable media must be able to be secured. If this value entry is not added, the contents of the floppy disks in the drives will be available to all processes on the system. @#$Key 2 Auto restart shell if it stops HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\AutoRestartShell AutoRestartShell REG_DWORD Range: 0 or 1 Default: 1 (enabled) Specifies whether the WindowsáNT user interface (usually Explorer.exe) is restarted automatically if it stops unexpectedly. If this value is set to 1, and the Windows NT user interface, or one of the third party components of the user interface fails, the interface will be restarted automatically. If this value is set to 0, the user must restart the interface by logging off and logging on again. @#$Key 2 Don't display last user name when logon HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\DontDisplayLastUserName DontDisplayLastUserName REG_SZ Range: 0 or 1 Default: 0 (false) By default, Windows NT displays the name of the last person to log on in the Username space of the Logon Information dialog box. If you add this value entry and set it to 1, the Username space is always blank when the Logon Information dialog box appears. Note: You can use the System Policy Editor to change this value. @#$Key 2 Set a message when the user logon HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\LegalNoticeCaption LegalNoticeCaption REG_SZ Range: String Default: (none) Specifies a caption for a message to appear when the user presses CTRL+ALT+DEL during logon. Add this value entry if you want to add a warning to be displayed when a user attempts to log on to a Windows NT system. The user cannot proceed with logging on without acknowledging this message. To specify text for the message, you must also specify a value for LegalNoticeText. Note: You can use the System Policy Editor to change this value. LegalNoticeText REG_SZ Range: String Default: (none) Specifies the message to appear when the user presses CTRL+ALT+DEL during logon. Add this value entry if you want to add a warning to be displayed when a user attempts to log on to a Windows NT system. The user cannot proceed with logging on without acknowledging this message. To include a caption for the logon notice, you must also specify a value for LegalNoticeCaption. Note: You can use the System Policy Editor to change this value. @#$Key 2 Logon Prompt HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\LogonPrompt LegalNoticeText REG_SZ Range: String Default: (none) Specifies the message to appear when the user presses CTRL+ALT+DEL during logon. Add this value entry if you want to add a warning to be displayed when a user attempts to log on to a Windows NT system. The user cannot proceed with logging on without acknowledging this message.

HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\Shell Shell REG_SZ Range: Executable names Default: Explorer.exe Specifies executables that are run by USERINIT and that are expected to be in the user's shell program. If for some reason Winlogon cannot start the entries listed in Userinit, then Winlogon will execute the entries in Shell directly. @#$Node 1 Shutdown @#$Key 2 Powerdown After Shutdown HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\PowerdownAfterShutdown PowerdownAfterShutdown REG_SZ Range: 0 or 1 Default: 0 on Windows NT Server, 1 on Windows NT Workstation Determines whether the Shutdown and Power Off option appears in the Shutdown Computer dialog box. (This dialog box appears when you press CTRL+ALT+DELETE and then click the Shut Down button.) The option appears only if the value of this entry is 1. See also ShutdownWithoutLogon and NoClose. Note: The Power Off option is not supported on all computers. You need to replace hall.dll! @#$Key 2 Shutdown Without Logon HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\ShutdownWithoutLogon ShutdownWithoutLogon REG_SZ Range: 0 or 1 Default: 0 on Windows NT Server, 1 on Windows NT Workstation Specifies whether the Shut Down button in the Logon Information dialog box is enabled. If the value is set to 1, users can click the Shut Down button to stop the operating system without logging on or turning off power to the computer.

If this value is set to 1, as the system stops, WindowsáNT fills all inactive pages in the paging file with zeros so that they cannot be read by another process. It cannot fill all pages with zeros because some are being used by the system or other remaining active processes. This is a WindowsáNT security feature. @#$Node 1 Control Panel @#$Key 2 Accessibility HKEY_CURRENT_USER\Control Panel\Accessibility @#$Key 2 Date/Time HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation @#$Key 2 Devices HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES @#$Key 2 Display HKEY_CURRENT_USER\Control Panel\Desktop @#$Key 2 Fonts HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts @#$Key 2 Keyboard HKEY_CURRENT_USER\Control Panel\Desktop @#$Key 2 Modems HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Unimodem @#$Key 2 Mouse HKEY_CURRENT_USER\Control Panel\Mouse @#$Key 2 Multimedia HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\MULTIMEDIA @#$Key 2 Ports HKEY_LOCAL_MACHINE\HARDWARE\RESOURCEMAP\ @#$Key 2 Printers HKEY_CURRENT_USER\Printers\ @#$Key 2 International Settings HKEY_CURRENT_USER\Control Panel\International @#$Key 2 SCSI Adapters HKEY_LOCAL_MACHINE\HARDWARE\RESOURCEMAP\ScsiAdapter\ @#$Key 2 Services HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ @#$Key 2 Sounds HKEY_CURRENT_USER\APPEVENTS\SCHEMES\APPS\.DEFAULT @#$Key 2 Tape Devices HKEY_LOCAL_MACHINE\HARDWARE\RESOURCEMAP\OtherDrivers\TapeDevices\ @#$Key 2 UPS HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UPS\ @#$Node 1 Automatically Running Programs Everytime Windows Starts @#$Key 2 Auto Run when Windows NT starts in early state HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager Add the values with desired names and values. All programs start in early state of Windows NT loading. Value examples: autocheck autochk * /r\DosDevice\<drive letter>: - check all drivers autocheck autochk * - auto check autocheck autochk /k:x * - exclude drive x from checks Only for NT 4.0 with SP2 or higher chkntfs /x <drive letter>: e.g. chkntfs /x f: would exclude the check of drive f: To set the system back to checking all drives just type chkntfs /d @#$Key 2 Services Run HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices The programs started from this key are activated before user login. Examples: SystemTray (systray) Network Monitor Agent (nmagent.exe) etc. Note: You may add manually only programs that specially designed to run as service. @#$Key 2 All Users Run HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run For each program you wish to start automatically create a new string value using a descriptive name, and set the value of the string to the program executable. e.g. To automatically start Notepad, add a new entry of "Notepad"="c:\windows\notepad.exe" Note: Remember to include the full path, if the directory is not included in your default search path. @#$Key 2 Run Programs only for Current User HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run If you activated the multiuser environment you may add auto start programs for each user/ To automatically start Notepad, add a new entry of "Notepad"="c:\windows\notepad.exe" Note: Remember to include the full path, if the directory is not included in your default search path. @#$Key 2 Run Services Once HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServicesOnce The Windows installation system uses this key to setup software. All programs that started from this key loaded only one time and before programs from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices @#$Key 2 Run Once HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run If you want a program to run only once and then never run again, perform the above but add the values under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce. Once the program has run it gets deleted from the RunOnce key. @#$Key 2 Specifies executables to be run by Winlogon in the system context HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\System System REG_SZ Range: Executable names Default: lsass.exe Specifies executables to be run by Winlogon in the system context. These are activated during system initialization. @#$Key 2 Set executables to be runned when a user logs on HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\Userinit Userinit REG_SZ Range: Executable names Default: USERINIT,NDDEAGNT.EXE Specifies executables to be run by Winlogon when a user logs on. These executables are run in the user context. The first entry (USERINIT) is responsible for executing the shell program. NDDEAGNT.EXE is needed to run NetDDE. @#$Key 2 Rename Files on reboot HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\FileRenameOperations Entries for the FileRenameOperation support the MoveFileEx delayed-rename and delayed-delete capabilities. Entries are stored under this Registry path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\FileRenameOperations These entries should be maintained only by the system. @#$Key 1 Creating Program Aliases in Windows HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths A hidden feature in the Windows registry allows you to create program aliases. Allowing you to create, for example, an alias called EDIT.EXE that when executed actually runs another program, e.g. NOTEPAD.EXE 1. Using Regedit, open the key found below. There should be a number of sub-keys already visible below the key. 2. Create a new sub-key, and rename it to the name of the alias you wish to create (e.g. EDIT.EXE). 3. Modify the (default) value to equal the fully qualified path and filename of the application you want to be launched when you execute the alias (e.g. 'c:\windows\notepad.exe'). 4. Exit Regedit, and to test use the Start | Run command type in the name of your alias (i.e. EDIT.EXE) and the aliased program should be launched, in this case Notepad. @#$Key 1 Uninstall Applications HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall All Windows 9x or NT compatible programs must include an Uninstall program, sometimes though the program may get removed but entry in Add/Remove programs doesn't, from this key you can remove those orphaned entries. To see which application each sub-key represents, open it and there should be at least two values 'DisplayName' and 'UninstallString'. 'DisplayName' is the name used in the Add/Remove programs list, and 'UninstallString' is the program used to uninstall the application. To remove a program from the list you can simple delete the sub-key representing that program. @#$Key 1 Registry Size HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\RegistrySizeLimit RegistrySizeLimit REG_DWORD Range: 0 -or- Megabytes: 4 - 0xFFFFFFFF (Actual range: 4MB ù 80% of paged pool) Default: 25% of the size of the paged pool Establishes the maximum amount of paged pool space (and disk paging file space) that can be consumed by Registry data from all applications. (It does not allocate space in the paged pool, nor does it assure that the space will be available if needed.) If the value of this entry is 0, the system adjusts the RegistrySizeLimit dynamically based on the size of the paged pool. If both RegistrySizeLimit and PagedPoolSize are set to 0, PagedPoolSize is set approximately equal to the amount of physical random access memory on the computer, and RegistrySizeLimit is set to approximately 25% of PagedPoolSize. If the value of this entry is 0xFFFFFFFF, the system sets RegistrySizeLimit to 80% of the size of the paged pool. This value entry is designed to prevent the Registry from consuming space needed by processes. The space controlled by RegistrySizeLimit includes the hive space, as well as some of the RegistryÆs run-time structures. Other Registry run-time structures are protected by their own size limits or by other means. Note: To ensure that a user can always start the system and edit the Registry, the Registry is not subject to the maximum set in RegistrySizeLimit until after the first successful loading of a hive (that is, the loading of a user profile). @#$Key 1 Size of System Memory Cache HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache Value: LargeSystemCache REG_DWORD Range: 0, 1, 2, 3 Default: 0 On servers, this value determines whether the file system cache or the working sets of processes are given priority for space in memory. To change this value, double-click Network in Control Panel, click the Services tab, then double-click Server. To favor the cache, click Maximize Throughput for File Sharing. To favor working sets, click Maximize Throughput for Network Applications. Values: 0 Minimize memory used. 1 Balance (cache and working sets have equal priority). 2 Maximize throughput for file sharing (the cache has a higher priority). 3 Maximize throughput for network applications (the working sets have higher priority). @#$Key 1 Changing the Location of Windows Installation Files HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\SETUP\SOURCEPATH\ if you need to change the location of Windows distributive set he value "SourcePath" @#$Key 1 Enable or Disable the CD-ROM Autorun HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CDRom This will stop applications from auto launching wehn you insert a CD-ROM disc. Set the Value "Autorun" to the "0" (disable) or "1"(enable). @#$Key 1 Disable PC Speaker sound on Errors HKEY_CURRENT_USER\Control Panel\Sound if you can't find a way to off your PC Speaker, you can a chance to do it: 1. Open a Key. 2. Locate the value 'Beep' if it doesn't already exist create it, by selecting Edit | New | String Value and naming the new value 'Beep'. 3. Modify the value of 'Beep' to either 'Yes' beeping enabled, or 'No' beeping disabled. @#$Key 1 Allows you to specify a different task manager HKEY_CURRENT_USER\software\microsoft\windows nt\currentversion\winlogon\Taskman Taskman REG_SZ Range: Executable name Default: (none) Allows you to specify a different task manager. @#$Key 1 Clear the Run history HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU Select the value to remove and press Del. @#$Key 1 The order in which the service is loaded HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GroupOrderList For a service listed under CurrentControlSet\Services, the value of the Group entry plus any Tag entry determines the order in which the service is loaded. But not all services have a Tag entry, and not all groups have an entry in the GroupOrderList subkey. The ServiceGroupOrder subkey specifies the order for loading groups. The entries in the key are all of type REG_BINARY. These are the default entries that define the order within groups: Base Filter Keyboard Class Keyboard Port Ndis Pointer Class Pointer Port Primary Disk SCSI Miniport Video @#$Node 0 Windows Enhancement @#$Key 1 Automatically View Thumbnails of Bitmap Files HKEY_CLASSES_ROOT\Paint.Picture\DefaultIcon This setting will make Explorer show us a "thumbnail" version of any bitmap files that happens to be in the current folder, rather than the generic bitmap icon ordinarily used. Open a registry key: HKEY_CLASSES_ROOT\.bmp and look to the Default Value (located on the right pane). If you use a standard assosiations you'll see "Paint.Picture" (or any name, for example "BMP_Pict"). Then go to the registry key HKEY_CLASSES_ROOT\Paint.Picture\DefaultIcon (or to HKEY_CLASSES_ROOT\BMP_pict\DefaultIcon) and change the Default Value to " %1". You need logoff and logon to see changes! @#$Key 1 Full Window Drag Option HKEY_CURRENT_USER\Control Panel\Desktop\DragFullWindows This setting enables the Full Windows Drag function, which allow you to view the contents of window while dragging it across the screen, instead of just the standard outline. 1. Go to the Key. 2. Set the value of "DragFullWindows" to "1" to enable, if the value doesn't exit create it. 3. Exit Regedit and reboot. @#$Key 1 Can I enable the mouse snap-to? HKEY_CURRENT_USER\Control Panel\Mouse 1. If the value SnapToDefaultButton not exists, add a new string value "SnapToDefaultButton" (watch the case). 2. Set this value to 1. 3. Logoff and login again @#$Node 1 Explorer @#$Key 2 How can I open a command prompt at my current directory in Explorer? HKEY_CLASSES_ROOT\DIRECTORY\SHELL\ 1. Add a new key and enter a name of DOSHere (or anything else) 2. Under the new key add another key named "command" (only in lowercase). 3. Under the key (DOSHere) double click on (Default) and enter a name that will be displayed when you right click on the directory, e.g. "&DOS Command Prompt Here" 4. Move to the command key and again double click on (Default) and enter c:\cmd.exe /k cd "%1" 5. That's all! If you want to add this feature to files: go to the HKEY_CLASSES_ROOT\*\shell\ and repeat steps 1-5. @#$Key 2 Adding Explore From Here to Every Folder HKEY_CLASSES_ROOT\*\shell\ When you right click on any file this will give you a popup menu and an option to "Explore From Here", which will open up and explorer window of this file. 1. Go to the HKEY_CLASSES_ROOT\*\shell\rootexplore key, if it doesn't already exist then create it. 2. Edit the "(Default)" setting to read "E&xplore From Here". 3. Under rootexplore create a new key called "command", and edit the "(Default)" setting to read "explorer.exe /e,/idlist,%i". You not need to reboot! Open explorer and go! If you want to do it for folders: go to the HKEY_CLASSES_ROOT\DIRECTORY\SHELL\ and repeat procedure. @#$Key 2 When I double-click on My Computer, I want it to launch Explorer HKEY_CLASSES_ROOT\CLSID\20D04FE0-3AEA-1069-A2D8-08002B30309D\Shell\ 1.

Add a value to the Command key as a regular string value, with no name. 5. As the string, enter Explorer.exe. The next time you double-click My Computer, it will launch Explorer, and not My Computer. If you want to make the system use My Computer again, take out the two values listed. @#$Key 2 Prevent Open Explorer from restarting when you restart HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\ If you wish to prevent certain open (or minimized apps) such as Explorer.exe or Control Panel from automatically opening when you restart, go to the key. If the right hand pane doesn't have an entry for NoSaveSettings that is type REG_BINARY, add it. Now, change value to hexadecimal 1 (right hand pane will look like 01 00 00 00) Close all applications (or you will get a scary message) and reboot. @#$Key 2 Is there a way to automatically refresh the contents of my folders? HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Update\UpdateMode 1. Go to the Key. 2. Edit the UpdateMode value, and change it to 0 in Windows NT or 00 in Windows 95. The next time you make changes in Explorer, they will be immediate. @#$Node 1 Icons and Shortcuts @#$Key 2 Displaying Hi-Color Icons HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics\Shell Icon BPP The key let's you display icons in high-color mode, without having to install the Plus Pack option. Note: You need a graphics card capable of displaying above 256 colors for this to be useful. Value: "Shell Icon BPP"= "16" @#$Key 2 Removing Icons from your Desktop HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace This key contains a number of subkeys which hold information about the namespace extensions of icons on your desktop. Through this key you can control which icons are visible on the desktop, including the My Computer, Inbox, MSN and Internet icons. The name of each key is a globally unique identifier (GUID), and the default value of each key is a human-readable name for the namespace extension, although this is not the same name as the icon on the desktop. To delete an icon from your desktop: 1. Step through the subkeys until you find the key representing the icon you want to remove from your desktop, delete the key and the icon should disappear. @#$Key 2 Desktop Icon Redraw Frequency HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer If you desktop icons are redrawing too frequently, change this setting.

Note: In the same key, you should also be aware of, and possibly set: "Pattern"="(None)" "TileWallpaper"="0" @#$Node 1 Creating a Shortcut to the System Folders @#$Key 2 What is CLSID? HKEY_CLASSES_ROOT\CLSID Everything in Windows is dealt with as a number instead of as a name. People, however, tend to deal with things by name. CLSID is where all the numbers are listed for icons, applications, directories, file types, and more. Each one must be unique, and is assigned to the manufacturer by Microsoft. The manufacturer then puts the CLSID into the installation program files so it can update the Registry upon installation. For example: Create a new folder on your desktop and name it "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" It should look like the normal Control Panel icon (not a shortcut). You can now move the icon anywhere on your desktop or start menu. The same can be achieved for others by substituting these values: For Dial Up Networking Dial-Up Networking.{992CFFA0-F557-101A-88EC-00DD010CCC48} For Printers Printers.{2227A280-3AEA-1069-A2DE-08002B30309D} For Control Panel Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D} My Computer My Computer.{20D04FE0-3AEA-1069-A2D8-08002B30309D} For Network Neighborhood Network Neighborhood.{208D2C60-3AEA-1069-A2D7-08002B30309D} For the Inbox InBox.{00020D75-0000-0000-C000-000000000046} For the Recycle Bin Recycle Bin.{645FF040-5081-101B-9F08-00AA002F954E} For more check out the HKEY_CLASSES_ROOT\CLSID key. @#$Key 2 Removing Item Types from the New Menu HKEY_CLASSES_ROOT\.txt\ShellNew When you right-click on your desktop or other selected applications there is a New sub-menu which contains a list a default templates. This list can be modified to include only the templates you want. Each template exists in the [HKEY_CLASSES_ROOT] hive associated with a file extension. Whether it is visible or not in the New menu is controlled by whether the related entry has a sub-key called 'ShellNew'. For example on the New menu there is usually an entry for "Text Document". This is visible because of the key: [HKEY_CLASSES_ROOT\.txt\ShellNew] If you were to rename the key so it no longer had a sub-key called 'ShellNew' by changing it to [HKEY_CLASSES_ROOT\.txt\ShellNewOld] it would disappear from the New menu. 1. Open Regedit, and using the Find function (Ctrl+F) search for any values of 'ShellNew'. 2. Several should be found under the [HKEY_CLASSES_ROOT] hive, if you do not want them to be displayed rename 'ShellNew' to 'ShellNewOld'. Note: Changes should take place immediately without needing to reboot. @#$Node 1 Menu @#$Key 2 How to set the delay for cascading menus?

HKEY_CLASSES_ROOT\Exefile In Internet Explorer, when I download things from the Internet, it asks whether I should save the .EXE file to disk or if it should just run it. There is also a selection for it not to ask me again. I told it to open the file, and never to ask me again, but I have changed my mind. How do I get the dialog box back? The setting is in HKEY_CLASSES_ROOT\Exefile for either Windows NT or Windows 95. Change the EditFlags value from d8 07 01 00 (don't ask any more) to d8 07 00 00 (ask every time). @#$Key 1 How to change a dial-up user name? HKEY_CURRENT_USER\RemoteAccess\Profile\ 1. Go to the Key. 2. Open a subkey with a your dial-up name. 3. Change a value "User" to desired name. 4. Logoff and logoon again. @#$Key 1 Increase perfomance of Internet conncetion by change MTU value HKLM\System\CurrentControlSet\Services\Class\NetTrans\ By default, Windows NT attempts to discover the maximum transmission unit (MTU) of all connections beyond your local subnet. Limiting TCP segments to this size reduces fragmentation at the routers along your connection path, increasing your throughput. You may have inadvertantly disabled this feature while tuning your network. Tip! You can change this value for network adaper or dial-up adapter! 1. Go to the Key. There are many subkeys under it (0000,0001,0002...). Find a key with the value "DriveDesc"="TCP/IP". 2. If a DWORD value MaxMTU not exists, create it. Set it to 576. MaxMTU specifies the maximum size datagram IP that can pass to a media driver. Subnetwork Access Protocol (SNAP) and source routing headers (if used on the media) are not included in this value. For example, on an Ethernet network, MaxMTU will default to 1500. The actual value used will be the minimum of the value specified with this parameter and the size reported by the media driver. The default is the size reported by the media driver; an Ethernet network defaults to 1500 bytes and a Point-to-Point (PPP) Protocol dial-up connection defaults to 576 bytes. @#$Node 0 Security @#$Key 1 Locking down that desktop HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer Desktop restrictions can be implemented by editing the following Explorer values in the registry: (all values default to 0) NoCommonGroups REG_DWORD set it to 1 so that common program groups do not appear on the Start menu.
