I have a Athalon 64 X2 5200+ CPU based system with 2 GB DDR2 RAM & 250 GB Hard Disk . I have a GeForce 8400 GS Card with 512 MB Ram installed in it as well . The Driver version of this card is 22.214.171.12460 as shown by Device Manager . I just read that the minimum requirements for Windows 7 are - * 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 As you can see , my System meets all the requirements for Windows 7 except the last one (which I am not sure of ) . Is my System meeting the last requirement as well ?
