Windows XP will not find the text you are scanning for

You must have noticed that there is a difference in searching function between Windows XP and Windows prior to XP.
XP has a known issue for not finding a number of File Types when you do a Search for Files "containing text" or using the "A word or phrase in the file" option. Windows XP will not find the text you are scanning for.

Why ?
Microsoft wanted to make XP faster than the previous versions of Windows. Thus it eliminated the capability to search all file.XP checks only a number of file extensions.The cause is the lack of a PersistentHandler value in the Registry for this type of file.

How To Fix:-

1]Change the default value of PersistentHandler key:-

Now Navigate to [HKEY_CLASSES_ROOT.XXXPersistentHandler.You can also find PersistentHandler key by:-
Highlight HKEY_CLASSES_ROOT>goto Edit>Find>in the Find what: box type:PersistentHandler>Enter/Find Next
Now just change the default value:-Double click on the Default value present in the right pane and copy and paste this value:{5e941d80-bf96-11cd-b579-08002b30bfeb}.Close the registry editor and reboot your system.

Obtain the latest service pack for Windows XP and then turn on the Index file types with unknown extensions option.

2.A]Through Registry:-
To configure the search to include all file types:
1]Start>Run>Regedit>Ok. Now navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex.
2.]Double-click the FilterFilesWithUnknownExtensions Value Name, a REG_DWORD data type, and set the data value to 1.
3] You must restart your computer for this change to take effect.

2.B]Through GUI:-

1] Click Start, and then click Search (or point to Search, and then click For Files or Folders).
2] Click Change preferences, and then click With Indexing Service (for faster local searches).
3]Click Change Indexing Service Settings (Advanced). Note that you do not have to turn on the Index service.
4] On the toolbar, click Show/Hide Console Tree.
5] In the left pane, right-click Indexing Service on Local Machine, and then click Properties.
6]On the Generation tab, click to select the Index files with unknown extensions check box, and then click OK.
7] Close the Indexing Service console.
