If you're excited that Windows 7 Beta will be available as a free download soon, Microsoft also detailed the minimum system requirements for Windows 7. According to PC World, the requirements are:
- 1GHz processor (32- or 64-bit)
- 1GB of main memory
- 16GB of available disk space
- Support for DX9 graphics with 128MB of memory (for the Aero interface)
- A DVD-R/W drive
Those requirements are basically identical to the system requirements for Vista, which—considering the nearly three-year span between Vista and Windows 7—should make Windows 7 a much more viable upgrade to those of use who don't want to buy a new PC just to upgrade their OS.
