Here's what you need, as documented on MS website, to run Windows 7:
1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
16 GB available hard disk space (32-bit) or 20 GB (64-bit)
DirectX 9 graphics device with WDDM 1.0 or higher driver
You ain't getting that in the chip inside the surface. The tablets in question aren't built with the robust architecture as a traditional fully featured pc/laptop.
