Search Companion Starts when open a folder

This is the most weird problem i have ever faced , here is my problem when i double click or RIGHT CLICK on a folder to open it the Search get opens ?

What is going on can any one help me ?

you have change your default setting :

• Click on Start/ Run
• Type in : regsvr32 / i shell32.dll
• C;ick on OK
• Check if this technique works. If this is not the case, proceed to method

Be careful to respect the spaces

Now, repeat right-click the folder/file of your choice and see that everything is restored.

To resolve this problem, edit the registry to set the value data for the Default string value in the registry keys that are described in the "Cause" section of this article to none:

1. Start Registry Editor (Regedt32.exe).
2. Locate and then click the Default value under the following keys in the registry if this problem occurs with folders:

• HKEY_CLASSES_ROOT\Directory\shell
• If this problem occurs with drives:
• HKEY_CLASSES_ROOT\Drive\shell

3. Click Modify on the Edit menu.
4. Type none in the Value data box, and then click OK.
5. Quit Registry Editor.

Thanks for the help it work correctly know know ,,but can any one tell me how did this happen ?

This problem occurs when you open the Edit File Type dialog box for the Drive or File Folder registered file types. For example, this problem occurs for folders if you complete the following procedure:

1. Open the folder, and then click Folder Options on the Tools menu.
2. Click File Folder in the Register file types list, and then click Advanced.
3. After you perform this procedure, the None setting is removed from the value data for the Default string value in the following registry key:
HKEY_CLASSES_ROOT\Directory\shell
