Windows Tools- PsExec


The PsExec is a windows internals utility to execute commands in a remote machiene from your command line.  This is very useful for windows system administrators since It allows you to run programs and processes on remote systems, using all the features of the interactive interface of console applications, without having to manually install the client software. The main advantage of PsExec is the ability to invoke the interactive command-line interface on remote systems and remotely run programs (in the background and in the interactive mode) and execute any commands.
The PsExec utility is one of the most popular programs of the PsTools package from Sysinternals. You can download it on this page: https://docs.microsoft.com/en-us/sysinternals/downloads/psexec
