I want to know the minimum space requirement for each version of Windows (XP-7)?

Just be aware that the minimum stated for XP is really the MINIMUM! Don't expect to put XP on a system with a 1.5 GB disk and 64 MB RAM and be able to run programs with anything like reasonable speed. Do expect your disk to show constant activity (thrashing).
With Win7 you can actually run interesting things in 1 GB RAM as long as you can get it loaded on the disk ok. Not sure how tight 16 GB would make it.
