(version, csd, ptype)referring to version number, CSD level and OS type (multi/single processor).
As a hint: ptype is
'Uniprocessor Free' on single
processor NT machines and
'Multiprocessor Free' on multi
processor machines. The 'Free' refers to the OS version being
free of debugging code. It could also state 'Checked' which
means the OS version uses debugging code, i.e. code that
checks arguments, ranges, etc.
