Well you need to have remote access to each user folder with admin rights to run a script.
You write your own script on your compter to go to each system, login as appropriate, and execute the desired user folder script.
I would envison a simple loop that does all that but pulling the user login information from a list versus 75 iterations of code going to each user.
Probably a variety of ways various administrative tools/software to do all of that.
Write some code and try execution on one or two remote test systems. See what happens, correct as necessary, test again.
