Visual Studio 2008 Team Explorer Problem after Windows Update

After a Windows Update from 26.08, Team Explorer stopped working. I received the following error:

TF30421: Team Explorer could not connect to Team Foundation server <servername>. The server may be offline
or the network is unavailable. Contact your Team Foundation Server Administrator to confirm that the server is available on the network.
Use the connect to Team Foundation Server Command on the Tools menu to retry your connection to the server.
The server returned the following error:Unable to cast COM object of type ‘System.__ComObject’ to interface type ‘Microsoft.VisualStudio.OLE.Interop.IServiceProvider’. This operation failed
because the QueryInterface call on the COM component for the interface with IID
‘{6D5140C1-7436-11CE-8034-00AA006009FA}’ failed due to the following error: No such
interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

After some Internet research I found out that it might be related to some unregistered DLLs, as mentioned here. But following the steps described did not help. I searched a little bit more, and found this article:

Note that the article is from August 2009 and it mentions a completely different problem! But I saw that registering “%ProgramFiles%\Internet Explorer\ieproxy.dll” might help. So I did that using Command Prompt, run as Administrator, then rebooted. After rebooting, Team Explorer worked fine again.

Does anybody know why Team Explorer relies on Internet Explorer? 🙂
