Compare software on two different domain computers
All,
I found these PowerShell commands on a website to pull a software lists from two separate machines and compare the lists. My questions are:
1. Is it possible to automate this with PowerShell ISE?
2. Can this be scripted so it accepts the domain credentials and both computer names as variables?
3. Can the output be saved to a network share? \\servername\myshareddrive
I have figured out how to run single commands in PowerShell, but I have zero experience with PowerShell ISE and scripting multiple commands. What would the script look like if this can be accomplished?

Hi Brad,
I am not at a machine where I can test this right now, but I would suggest a script something like this:
Hope that helps at least move you in the right direction.

ForEach ($Computer in Get-ADComputer -Filter *)
{
Get-WMIObject -ComputerName $Computer -Class Win32_Product
}
Hope that helps at least move you in the right direction.

I just remembered seeing a script to do this already, and I found it on TechNet:

Appears to be exactly what you need - run it against each of the machines and compare the outputs.
I note they suggest not using the Win32_Product class, so please ignore my previous post.
