Team Explorer Window Won't Open Or Is Blank

If recently worked with several developers that were unable to open the Team Explorer 2008 window (or if they did open it, the window was blank).  They had pre-release versions of Visual Studio 2008 installed and despite following the instructions on uninstalling previous versions, were unsucessful.  Having found the fix for this issue, I thought I'd share it in case anyone else encounters it.

Open a Visual Studio 2008 command prompt and run the following command:

devenv /setup

It will take awhile for this command to complete, but afterwards, the issue should be resolved.  Here is documentation on the /setup switch if you would like to know more about it.
