Vista wasn't that bad from purely OS side. On a VM it runs pretty stable.

However, Microsoft made a huge change to how the OS and drivers worked. If you still use Windows, you are still benefitting from some of the changes.

However HW vendors usually ship rather broken drivers, it was doubly bad since Vista overhauled the driver interface. By the time all vendors fixed their shitty and badly tested drivers we already had 7. It is also partly Microsoft's fault since they had absolute chaos in Vista development due to shitty hacks on top of hacks that was the consumer OS (XP).

Similarly Vista was very heavy for its contemporary average hardware. By the time HW caught up, 7 was released.
