Neither does Windows by the way. Vista was the last Windows version that used more resources than its predecessor (XP). From Windows 7 onwards (released 2009), each new release uses the same or fewer resources. Microsoft has put a lot of effort into this so that Windows can run on tablet devices.
Just for giggles today, after reading
@fincoder 's comment above, and
for testing purposes only, I dragged out and old desktop PC from the storeroom.
AMD Sempron 1.8GHZ, 2 GB ram 320GB Spinner and loaded it with Win 10 Home.
There was no OS on it but I think it must have had Vista originally as there is a Vista OEM key on the side.
It surprised me how snappy it was. So I removed one of the two ram modules and booted it up again.
And again I was surprised how snappy it was.
Now it didn't have an AV or any other programs so (I thought) It would soon buckle if it had.
With only 1GB ram with Emsisoft installed, 1 tab open in Firefox, and wordpad open it was still reasonable.
You would think that anything more than that would have caused it to start paging, which would have degraded performance significantly - but no - it was still responsive.
Might try it with Win 7 and Vista...(if I can find that Vista disk..)
