Some software will work, Others will not. It depends on where they write to in the instillation.
If you already have the hardware/software you can use the windows vista advisory tool.
It gives you the low down, Word.
P.s. I would hold off on vista till the first service pack to be honest, Although i have it installed and it seems fine, theres a few programmes that dont work. but i'm dual booting at the moment.
Anyone in the uk wanna give me a job...Please
