I'm currently using a Vista computer at the moment, and am probably one of the few people who will actually bother troubleshooting problems on the OS. Most of the problems with it were in business and school environments, which usually require computers to be connected to a domain, so I assume it's mostly a domain issue. The only issue I have with Vista tbh is that when I use PMD editor's MMD view function, it doesn't show the model how it looks in MMD, it just shows everything tinted differently. Strange.
Vista is a piece of diarrhea dump bullcrap that will be unsupported in 2017. We only have 6 years to go! Oh yeah.Vista is usually installed with the Really Sucky Virus. It is the worst OS ever excluding Mac. It is the devil in computer form! There you go kids! My (true) opinion of Windows Vista!
