Dear PowerShell Experts,
I found this script in the PS gallery Script for Product Keys and it says it supports being run against multiple remote
machines. I would like to input a text file of several machine names or .csv file, but I'm unsure of how to use it. Essentially, its primary function is to obtain the product key from all machines in your environment. Can someone please
show me how to use the script below? Or potentially point me to another way to pull keys from a list of remote machines? (Windows 7 32/64 bit) Thanks in advance!
