#10
I was going to say, I had installed Windows 10 Build 10240 (hoping to set myself up as an Insider again). I ended up bailing because of activation issues but that's not the point. I did notice that Windows 10 ran very quickly on my old HP Compaq Small Form Factor DC7600 (1 GB of RAM and a 20 GB IDE HDD).
However, I bailed and installed the x86 build of Windows 8.1. Well crap, it's even FASTER, and it looks nicer. For those who lament Windows 7, I think 8x with Classic Shell just looks and acts like a flatter, faster Windows 7. That's just me though.
