I never used vista before, only in 2015. Everyone hated vista because of it was "unstable" and people use solitare crashing windows. But it happens only in VM's because vista doesnt like VM's. Some software and games stopped supporting vista, but extended kernel helps. Yes, some games cant run on vista, but hey, the vista support community works really hard to get newer versions of software to run on vista. Oh, also, here are my specs:
Intel i-5 520M
5GB Ram
Intel HD Graphics
240GB SSD + 1TB HDD
Windows Vista English 64-Bit
Vista runs very well on these specs!
Forgot to say, i use Dell Latitude E6410
