From the guy that brought you Windows 3.11 on a phone, and Windows 7 running on 128 MB of RAM comes a new feat: Windows 8 on 128 MB of RAM. It doesn’t do a whole lot, but it’s possible. Definitely not recommended for any purpose other than showing it can be done (can you even buy DDR2 or DDR3 in 128 MB sticks?!).
