Seeing as how a bunch of people here have begun to switch over to Windows Vista and many more may be considering I thought it might be helpful to create a list of incompatible software so that people may better decide.
Also make sure to try and troubleshoot it(compatibilty mode etc.) before posting

Completly Incompatible Software
2006 FIFA World CUP(BSOD--memory error?)
Unreal Tournament(Fails Install)

Semi-Incompatible Software(useable but some problems)
Sid Meier's Pirates(land and shallow water is very bright)
Realtek ALC850 VISTA Drivers(occasional stuttering)
Folding@Home(extractor must be run in compatiblity mode)
Yohoho Puzzle Pirates(installer has severe graphical glitches,occasional artifacting in game)

Just remember, this list only reflects what works with the Beta version, some programs will probably work just fine after the "Official" version ships... with a few patches and driver updates that is

Quote: As we mentioned previously with the special case of games, the problems relating to them are a combination of driver issues and DirectX issues. For some reason, the version of DirectX included with Vista does not have a completely working compatibility layer for pre-DirectX 10 games, while some games can't correctly detect DirectX 10 as a superset of DX9.0c. This has resulted in games seeing Vista as only having DirectX 9.0(a), which in turn causes some games to fail and start believing the system is out of date. Other games will not enable certain features such as SM3.0. Some DLLs are also missing from the current version of DirectX, such as the D3DX DLLs that come with the seasonal DirectX9.0c updates, and these need to be installed before games using them (such as Battlefield 2) can be used. Also, most games will still need administrative powers to run, as the use of anti-cheat and anti-copying protections such as PunkBuster and Safedisc require administrative power to do their checks
