Wait... That was not joke? Why would you replace windows 7 or 8 with vista? i mean i respect you guys if you use it for the fun of it but for serious computing purposes?! There is absolutely no benefit. Speed improvements in newer operating systems. i've used vista in past and it was horrible. Got little better with sp2, but in 2007 the rtm version oh boy. Completely corrupted my hdd while copying 100 gb of family photos (never gonna forgive that).
You say vista is good for internet... Well i would not use vista for internet banking for example. Why would you take the risk? Also hardware support is way better in windows 7 and 8
i would say that you need at least windows 7 to run all apps that normal people do.
Here is my list of programs (since i dont care about vista idk if these do work or dont)
Edge browser, Discord, Skype, Avast, office 2019, spotify, itunes (for my phone), obs, share x, GOG launcher, Steam, Origin, Uplay, Teamviewer.
