Any windows admin will no doubt have used the amazing sysinternals tools. Having quick access to the tools has become a lot easier. Using the common command pusd you can connect upto the live repository of sysinternal tools and run the programs straight from the command line. No need to download all the tools then uncompress the archive just to run a specific tool you are after.
From a command prompt simply run
and it will map a drive to the sysinternals tools. Then simply run psexec, psloggedon, bginfo etc all from the command line or the mapped drive.
