To create context menu handler under Computer in Windows Vista, navigate the registry to: HKEY_CLASSES_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\shell
{20D04FE0-3AEA-1069-A2D8-08002B30309D} is GUID (Global Unique Identifier of Computer)
NOTE: There is no need to convert the String value (REG_SZ) to String Expand (REG_EXPAND_SZ).
Create a Windows Vista registry key as you wish, lets us say gpedit & set the default value like “Group Policy”; now create another key named as command and set the default value as “mmc.exe gpedit.msc”

Here is some registry code to add Services, Registry Editor, and Group Policy & so on.

After the applying the registry hacks your computer context menu will be become looks like:

Similarly you can add right click context menu handler to Desktop –you have to navigate HKEY_CLASSES_ROOT\Directory\Background\shell
and add same registry as for Computer context menu handler

Its time to go fast and there is also need in Windows Vista. Under explorer; we can add system folder and control panel applets to Computer, Control Panel and Desktop or remove unwanted shortcut from all these.

I have categorized the system folder to major three types.

Now navigation as:

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 we have used Resource Hacker. Resource Hacker 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 Mcft Windows 95/98/ME, Windows NT, Windows 2000 and Windows XP operating systems.

get this from h**p://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 we 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. we 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\ Mcft\ 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.

If you want to access the Disk Defragment tool in Windows Vista or in XP, you usually have to either access it through the Windows start menu, or open up from the drive properties window. Instead of going through these lengthy steps, we can use a simple registry tweak to add Disk Defragment option as a menu item to the drive right-click menu.The steps for this Windows Vista registry tweak is given below:

Open Windows Vista start menu and run regedit from the run box to open the Registry Editor and follow the steps:

• Navigate to the following registry key:

• Create a new registry key called “runas” and set it’s default value to”Defragment“.
• If you want to hide this newly created right-click menu item behind the Shift key right-click menu, then add a new string called “extended” with no value.
• Then create another registry key called “command” and set the value of this newly created registry to the following:

defrag %1 -v

• Close the Windows registry editor window and reboot your computer to take effect the changes.

To check the results of your Windows Vista trick, just right-click on the drive icon in Computer in Windows Vista and you should see the newly created Disk Defragment menu item.

Ever experienced this? You ask Google to look something up; the engine returns with a number of finds, but if you try to open the ones with the most promising content, you are confronted with a registration page instead, and the stuff you were looking for will not be revealed to you unless you agree to a credit card transaction first….
The lesson you should have learned here is: Obviously Google can go where you can’t.Can we solve this problem? Yes, we can.
We merely have to convince the site we want to enter, that WE ARE GOOGLE. In fact, many sites that force users to register or even pay in order to search and use their content, leave a backdoor open for the Googlebot, because a prominent presence in Google searches is known to generate sales leads, site hits and exposure.Examples of such sites are Windows Magazine, .Net Magazine, Nature, and many, many newspapers around the globe.How then, can you disguise yourself as a Googlebot? Quite simple:
by changing your browser’s User Agent.
Copy the following code segment and paste it into a fresh notepad file. Save it as Useragent.reg and merge it into your registry.
