Question: what is the minimum requirement to install windows 7?
Answer: The minimum requirements for Windows 7 are modest by today's standards: 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor. 1 GB RAM (32-bit) or 2 GB RAM (64-bit) 16 GB available disk space (32-bit) or 20 GB (64-bit) -- just for the OS, not applications or data files.
