I remember installing Windows 10 on my laptop when I was in high school, it was a decommissioned Thinkpad T410s from my dad's work. 4GB of RAM, Nehalem i5, a very early consumer SSD (OCZ, if I recall). I vividly remember my first thought being "wow this is really slow." Win7 ran like a champ on that machine.

My experience with Win10 on that laptop actually led me to buy a dumb gamer laptop for college. As those all do, it died prematurely, so I ended up back on the T410s for a while. I put KDE Neon on it. It was great!

If you're saying that you can install and use Win10 on a laptop with 1 GB of RAM, well yes I acknowledge that is true. But it's a purely academic exercise, it's not actually a usable computer for the overwhelming majority of people.

Maybe it would have been fine for my grandma. She was using a Pentium II running Windows XP to go on Facebook in the early 2010s.
