Vista SP1 Beta 1 does not contain any changes in this area.  

The open issue with Microsoft is SRQ070322604363 and the hot fix for
Vista RTM is KB 942219.

There is no runtime test that can be performed to determine if the hot
fix is applied.  When the hotfix becomes widely available we are going
to have to use either a Windows build number test or attempt to
enumerate the installed update list.
