XP support was dropped in 2014, Vista support was dropped last year (and this is the dopping of extended support)

Windows 7 will see the end of extended support in 2020, and has already seen the end of mainstream support.
We have an expression in Portuguese for Windows Vista:
Tudo o que nasce torto, tarde ou nunca se endireita.
Loosely translated, “Everything that is born crooked, late or never straightens”. Goodbye Vista, you shall not be missed.
Lol same
the only computers I’ve seen recently which even use Vista are old school computers, so I just assumed support for it was long gone
When will the IPhone 4S stop being supported? 
Yes, it’s still being supported.
When its chipset isn’t ~20% of our iOS user-base.
dear god
If you stop supporting it, it won’t be!
I meant for the foreseeable future.
thats because Vista didn’t work in the first place
The real reason they removed Vista support was because its software was too outdated to run FBIAgent.exe
It’s only 10%. All hail 4S.
That was a beautiful answer and you are a beautiful person.
Hats off to anyone still developing on vista.
I mean, if you think about it, Windows Vista is very similar to 7, it’s just that windows 7 looks prettier.
And then they made 8.1
Yes, it’s completely the same.
It’s just that you had to get a new Aero-compatible graphics card, and most devices didn’t have compatible drivers, only for you to find out you didn’t need them because Windows 7 didn’t have Aero nor needed completely re-written drivers.
Why was there even support for Vista in the first place?
You’re incorrect about Windows 7 not having Aero. 
If this is anything to go by, then windows vista is used less often than windows xp so there is that…
