what is minimum system requirements for Windows 7(os hint)

• 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 thesystem 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.
