That's Windows 95 on a 386, 4MB RAM, 85MB HDD and some incapable Trident ISA graphics card.
Up until the early 2000s my uncle was sporting a computer with specs similar to that, except that it was running Windows 3.1. Even that felt sluggish on that system, so I can well imagine how dreadfully slow Windows 95 must be on hardware like that.
Very good video btw, that dude breaks down even a painful process well enough that the viewer can actually enjoy watching it.
old Eee PC netbooks and installing things on them. Have quite a collection and boxes full of spare parts. The 7" ones won't run windows any more (not up to date windows anyway but they will run XP)
I had an old Eee PC netbook once! A 7" model, in white. My sister gave it to me about a decade ago as she had no use for it anymore and she hated that thing. I could see why since it wasn't exactly optimized: the poor little device was running Windows Vista, barely. When it came into my possession I installed Windows XP on it. I actually made decent use of it up until 2021, when it began having power problems.
My use for it was offline: I installed a bunch of emulators (NES, SNES, Mega Drive) on it and on my daily 1 hour train commute of the time I would whip out a controller and just play classics like Super Mario World and Sonic The Hedgehog on it, with headphones on.
Too bad netbooks aren't really a thing anymore, I quite liked that form factor, they'd fit snuggly in just about any bag and were the right size for the flappy table thing on the train.
