PsInfo v1.77


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.


Just copy PsInfo onto your executable path, and type “psinfo”.

Using PsInfo

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).

Usage: psinfo [[\computer[,computer[,..] | @file [-u user
[-p psswd]]] [-h] [-s] [-d] [-c [-t delimiter]] [filter]

\\computer Perform the command on the remote computer or computers specified. If you omit the computer name the command runs on the local system, and if you specify a wildcard (\\*), the command runs on all computers in the current domain.
@file Run the command on each computer listed in the text file specified.
-u Specifies optional user name for login to remote computer.
-p Specifies optional password for user name. If you omit this you will be prompted to enter a hidden password.
-h Show list of installed hotfixes.
-s Show list of installed applications.
-d Show disk volume information.
-c Print in CSV format.
-t The default delimiter for the -c option is a comma, but can be overriden with the specified character.
filter Psinfo will only show data for the field matching the filter. e.g. “psinfo service” lists only the service pack field.


Example Output

c:> psinfo \development -h -d

How it Works

PsInfo uses the Remote Registry API to read system information from a system’s Registry, and WMI to determine whether Windows XP installations have been activated.
