Windows 7 is being touted as a light on resources OS. But really, how light is it? The answer may lie in the video, as someone has managed to run Windows 7 on a UMPC with a 600 MHz A100 Intel Processor with only 512 MB of RAM. The Experience Index gives a score of 1.2 which is more than Vista’s 1 on this very same UMPC. The installation was done using a USB DVD drive and installed on 18 GB of storage on the device. I wouldn’t even dare running Windows XP on such a configuration, let alone Windows 7. But it just works, with Aero!
