SYMPTOMS
When you click the Explore button on the ActiveSync toolbar in Microsoft Windows, the device Explorer window does not open.



CAUSE
This problem occurs because the Windows shell policy on your computer disables shell name extensions that are not trusted.

The shell policy sets the value of the  key to 1. This setting causes the shell to run only the shell extensions that are registered under the  key.



RESOLUTION
To enable the device explorer, add the ActiveSync extension to the list of trusted extensions. To do this, follow these steps:  Open a text editor such as Notepad, and then paste the following text in a blank document:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved] &quot;{49BF5420-FA7F-11cf-8011-00A0C90A8F78}&quot;=&quot;Mobile Device&quot;

 Save the file. Type .reg for the file name extension. Locate and then double-click the file. When you receive a message to add information to the registry, click Yes.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
