pstools is a very powerful command-line toolset for Windows:

Its only problem is GUI EULAs.  To get around these, create a CMD file containing the single line below:

regedit /s pstools-eula.reg

and a file name pstools-eula.reg containing the text below.  Then run the CMD file, and all of the pstools utilities will run silently.  Obviously, you can use the contents in both files in simpler manner in lots of different ways.
