When Microsoft released the official beta for Windows 7 a while back, it also published a set of system requirements. These were a general overview, and it seems that they have been updated to match the Windows 7 RC recently made available.
Here’s the list of initial system requirements Microsoft made available:
* 1GHz processor (32- or 64-bit)
* 1GB of RAM
* 16 GB of available disk space
* Support for DirectX 9 graphics with 128MB of memory (for the Aero interface)
And here, you will find the updated and final list of requirements:
* 1 GHz processor (32- or 64-bit)
* 1 GB of RAM (32-bit); 2 GB of RAM (64-bit)
* 16 GB of available disk space (32-bit); 20 GB of avaiable disk space (64-bit)
* DirectX 9 graphics device with WDDM 1.0 or higher driver
According to ZDNet, however, "If you are planning to run Windows XP Mode along with Windows 7, Microsoft is recommending a PC with a minimum of 2GB of memory and 15 GB of additional disk space." Microsoft stated, "In addition, Windows Virtual PC requires a PC with Intel-VT or AMD-V enabled in the CPU, as it takes advantage of the latest advancements in hardware virtualization."
