Pop A Banner Each Time Windows Boots

To pop a banner which can contain any message you want to display just before a user is going to log on, go to the key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WinLogon

Now create a new string Value in the right pane named LegalNoticeCaption and enter the value that you want to see in the Menu Bar. Now create yet another new string value and name it: LegalNoticeText. Modify it and insert the message you want to display each time Windows boots. This can be effectively used to display the company's private policy each time the user logs on to his NT box. It's .reg file would be:

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Winlogon]

"LegalNoticeCaption"="Caption here."

A Bunch of Registry Tips

Launch Regedit and go to the following Registry Key:

HKEY_CURRENT_USER/Software/Microsoft/CurrentVersion/Policies

Under this key, there will definitely be a key named explorer. Now under this explorer key we can create new DWORD values and modify it's value to 1 in order to impose the restriction. If you want to remove the Restriction, then you can simply delete the respective DWORD values or instead change their values to 0. The following is a list of DWORD values that can be created under the Explorer Key-:

NoDeletePrinter: Disables Deletion of already installed Printers

NoAddPrinter: Disables Addition of new Printers

NoRun : Disables or hides the Run Command

NoSetFolders: Removes Folders from the Settings option on Start Menu (Control Panel, Printers, Taskbar)

NoSetTaskbar: Removes Taskbar system folder from the Settings option on Start Menu

NoFind: Removes the Find Tool (Start >Find)

NoDrives: Hides and does not display any Drives in My Computer

NoNetHood: Hides or removes the Network Neighborhood icon from the desktop

NoDesktop: Hides all items including, file, folders and system folders from the Desktop

NoClose: Disables Shutdown and prevents the user from normally shutting down Windows.

NoSaveSettings: Means to say, 'Don't save settings on exit'

DisableRegistryTools: Disable Registry Editing Tools (If you disable this option, the Windows Registry Editor(regedit.exe) too will not work.)

NoRecentDocsHistory: Removes Recent Document system folder from the Start Menu (IE 4 and above)

ClearRecentDocsOnExit: Clears the Recent Documents system folder on Exit.

Nolnternetlcon: Removes the Internet (system folder) icon from the Desktop

Under the same key: HKEY_CURRENT_USER/Software/Microsoft/CurrentVersion/Policies you can create new subkeys other than the already existing Explorer key. Now create a new key and name it System. Under this new key, system we can create the following new DWORD values(1 for enabling the particular option and 0 for disabling the particular option):
NODispCPL: Hides Control Panel

NoDispBackgroundPage: Hides Background page.

NoDispScrsavPage: Hides Screen Saver Page

NoDispAppearancePage: Hides Appearance Page

NoDispSettingsPage: Hides Settings Page

NoSecCPL: Disables Password Control Panel

NoPwdPage: Hides Password Change Page

NoAdminPaqe: Hides Remote Administration Page

NoProfilePage: Hides User Profiles Page

NoDevMgrPage: Hides Device Manager Page

NoConfigPage: Hides Hardware Profiles Page

NoFileSysPage: Hides File System Button

NoVirtMemPage: Hides Virtual Memory Button
Similarly, if we create a new subkey named WinOldApp, we can add the following DWORD values under it(1 for enabling the particular option and 0 for disabling the particular option):

Disabled: Disable MS-DOS Prompt

NoRealMode: Disable Single-Mode MS-DOS.

Edit Windows Start Button

Step 1 - Modify Explorer.exe File

In order to make the changes, the file explorer.exe located at C:\Windows needs to be edited. Since explorer.exe is a binary file it requires a special editor. For purposes of this article I have used Resource Hacker. Resource HackerTM is a freeware utility to view, modify, rename, add, delete and extract resources in 32bit Windows executables and resource files (*.res). It incorporates an internal resource script compiler and decompiler and works on Microsoft Windows 95/98/ME, Windows NT, Windows 2000 and Windows XP operating systems.

get this from http://delphi.icm.edu.pl/ftp/tools/ResHack.zip

The first step is to make a backup copy of the file explorer.exe located at C:\Windows\explorer. Place it in a folder somewhere on your hard drive where it will be safe. Start Resource Hacker and open explorer.exe located at C:\Windows\explorer.exe.

The category we are going to be using is "String Table". Expand it by clicking the plus sign then navigate down to and expand string 37 followed by highlighting 1033. If you are using the Classic Layout rather than the XP Layout, use number 38. The right hand pane will display the stringtable. We’re going to modify item 578, currently showing the word “start” just as it displays on the current Start button.

There is no magic here. Just double click on the word “start” so that it’s highlighted, making sure the quotation marks are not part of the highlight. They need to remain in place, surrounding the new text that you’ll type. Go ahead and type your new entry. In my case I used Click Me!

You’ll notice that after the new text string has been entered the Compile Script button that was grayed out is now active. I won’t get into what’s involved in compiling a script, but suffice it to say it’s going to make this exercise worthwhile. Click Compile Script and then save the altered file using the Save As command on the File Menu. Do not use the Save command – Make sure to use the Save As command and choose a name for the file. Save the newly named file to C:\Windows.


Step 2 – Modify the Registry

!!!make a backup of your registry before making changes!!!

Now that the modified explorer.exe has been created it’s necessary to modify the registry so the file will be recognized when the user logs on to the system. If you don’t know how to access the registry I’m not sure this article is for you, but just in case it’s a temporary memory lapse, go to Start (soon to be something else) Run and type regedit in the Open field. Navigate to:

HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon

In the right pane, double click the "Shell" entry to open the Edit String dialog box. In Value data: line, enter the name that was used to save the modified explorer.exe file. Click OK.

Close Registry Editor and either log off the system and log back in, or reboot the entire system if that’s your preference. If all went as planned you should see your new Start button with the revised text.

Create A Special Folder In My Computer or Desktop

Create your own custom system folder, like "My Documents", that can not be deleted or renamed and place it on the desktop and My Computer.

Create the following series of keys and values in the registry at [HKEY_CLASSES_ROOT\CLSID] or [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID]. The GUID, globally unique identifier, can be a random number, in this example "FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345" is used. See this article for more GUID examples.

1)Create a new key called [HKEY_CLASSES_ROOT\CLSID\{FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345}] and set (Default) to equal the name of the folder e.g. "My Folder".

2)Create a new sub-key under the main key called "DefaultIcon" (i.e. [HKEY_CLASSES...ABCD1DE12345}\DefaultIcon]) and set (Default) to equal the filename for the icon you want to display e.g. "c:\windows\myicon.ico".

3)Create a new sub-key under the main key called "InProcServer32" (i.e. [HKEY_CLASSES...ABCD1DE12345}\InProcServer32]) and set (Default) to equal "shell32.dll", also create a new String value called "ThreadingModel" and set it to "Apartment".

4)Create a set of sub-keys starting at the main key "Shell\Open My Menu\Command" (i.e. [HKEY_CLASSES...ABCD1DE12345}\Shell\Open My Folder\Command]) and set (Default) to equal the command to execute when clicked, in this case explorer, e.g. "explorer /root,c:\MyFolder".

5)Create a set of sub-keys starting at the main key "ShellEx\PropertySheetHandlers\{FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345}" (i.e. [HKEY_CLASSES...ABCD1DE12345}\ShellEx\PropertySheetHandlers\{FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345}])

6)Create a new sub-key under the main key called "ShellFolder" (i.e. [HKEY_CLASSES...ABCD1DE12345}\ShellFolder]) and create a new Binary value called "Attributes" and set it to "00 00 00 00".

7)(Optional) To place the folder on the desktop add the following key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
Explorer\Desktop\NameSpace\{FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345}]

8)(Optional) To place the folder in My Computer add the following key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
Explorer\MyComputer\NameSpace\{FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345}]
