Sysinternals PsTools


PsInfo is a command-line tool that gathers key information about the local or remote system, including the type of installation, kernel build, registered organization and owner, number of processors and their type, memory size, the install date of the system, and if it's a trial version, the expiration date. PsInfo command-line switches also let you view installed hotfixes and software applications.


Copy PsInfo onto your executable path and type 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).
