Solutions for Not Able to Search files & Folder

Find the solutions for not able to search files & folder for eg: doc, folder or any other .extension.

To configure Windows XP to search all files no matter what the file type, obtain the latest service pack for Windows XP and then turn on the Index file types with unknown extensions option.

If you use this method, Windows XP searches all file types for the text that you specify. This can affect the performance of the search functionality. To do this:

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.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
Network administrators can configure this setting by modifying the registry. To do this, set the FilterFilesWithUnknownExtensions DWORD value to 1 in the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex

Change IE Title bar Text

Disabling Instant Search in Outlook 2007

Disabling Instant Search in Outlook 2007

I personally found this very useful when the Instant Search just completely broke. It returned nothing at all, and I needed to find a message quickly… so I just disabled the index temporarily.

Note: I'm not recommending that you just go and try this. Only use this as a troubleshooting technique, and only if you backup first.

Disable Instant Search

Click the tiny drop-down arrow next to the Instant Search box, and then choose Search Options from the menu.

You'll see a list of your data files or .pst files here, and you'll want to remove the checks next to each one.

When you close the dialog you'll get an extremely wide message telling you that you will need to exit and re-open Outlook.

Now when you restart Outlook, the search will work just like the old versions of Outlook did. That's right, it will be painfully slow.

To reverse these changes you can simply complete the same steps, but make sure to check the boxes. Note that when you re-enable Windows will rebuild the search index again, so it won't be available for a while.

Resolution for Word 2007 Spell Check & Grammar not working

Problem:

 In word 2007 Spell Check & Grammar is not working.

Cause:

The Proofing Tools information in the Windows registry is located in "HKEY_CURRENT_USER\Software\Microsoft\Shared Tools\Proofing Tools\1.0." On the system whose spelling        checker did not work, there exists a subkey named "Override" within the "1.0" key. The known good systems did not have an "Override" subkey.

Resolution:

1)      Close all word application if it opened.

2)      Delete the "HKEY_CURRENT_USER\Software\Microsoft\Shared Tools\Proofing Tools\1.0\Override" registry key. Or just run the Spell Check On.exe file attached in the mail. You need rename the extension of the file from .txt to exe before running.

3)      Restart word application again this time Spell Check & Grammar should work fine.
