The whole minimum HW requirements is so bullshit. It's all about bloat. I have a stick pc and a tablet with some Atom CPU, 2Gb RAM, that run W10 reasonably well. No rockets and will probably choke on many apps, but for web stuff (just don't keep more than 2-3 tabs open) media playing, and light stuff they are surprisingly capable. I have installed Antix Linux on one, and it's a really capable machine.
- Gigabytes. of. RAM.
