Vista was an okay OS, get tired of people saying it was bad. It wasn't bad at all, it was just a shock to people who'd started using a computer with XP or 2000 and had no experience of having to switch drivers. The memory handling wasn't that fantastic I do agree but I've got plenty of users on Vista and it works fine.
Note that Vista is Windows 6.0, 7 is 6.1 and 8 is 6.2 - check the build numbers.
