PsInfo is a command-line tool that gathers key information about the local or remote Windows NT/2000 system,
including the type of installation, kernel build, registered organization and owner, number of processors and their
type, amount of physical memory, the install date of the system, and if its a trial version, the expiration date.
By default PsInfo shows information for the local system. Specify a remote computer name to obtain information from
the remote system. Since PsInfo relies on remote Registry access to obtain its data, the remote system must be
running the Remote Registry service and the account from which you run PsInfo must have access to the
HKLM\System portion of the remote Registry.
In order to aid in automated Service Pack updates, PsInfo returns as a value the Service Pack number of system (e.g.
0 for no service pack, 1 for SP 1, etc).
