Here is a script that will run only once if completed successfully. It will also write a log in either case to a subfolder where it ran from with a computer name in the file name.
Yet another serial number generator. Ported from a vbscript found online.
Just feed a machine name to the script to get an output with a serial number into a csv file.

If there is no input, the local machine will be used.
