Windows Vista Service pack 2 is out and we are sure that not to many people will get so much excited about it, and while it might lift Windows 7 expectations, it sure could put them down them for a while as well.
If you have Windows Vista either 32 bit or 64bit you will probably want to install it, as this service pack should fix a lot of issues and make things better, but we would not expect miracles. We believe that it cannot really make things worse, as its sole purpose is to get things more compatible and better.
Note that you have to have the Service pack 1 installed before you get Service pack 2 on there.
The 32-bit version is here (348.3 MB) and you can download 64-bit version here (577.4 MB).
