"Top Level" technologies/products not supported on Windows Vista

We are investing a lot of time in ensuring applications that work on Windows XP will work on Windows Vista - and we have a great deal of info to help developers get their applications working on Windows Vista at www.devreadiness.org but after the info I shared on MSDE not being supported, I often get asked "Eric, what other products are not supported?". Well - the following is not meant to be definitive - but is a brain dump of where I think we are as of Release Candidate One.

No doubt there are more at this level - but that seems plenty to be getting on with!
