Set file associations with a script

So I’m ashamed to be presenting a scripting technique that doesn’t use PowerShell… but I don’t have the time right now to find out how to do it in PowerShell.

I’ve come across the need to set PDF files to open using Adobe Reader instead of another program. After looking into it, I found that I can create a batch file and use the assoc command, like so.

@echo off
assoc .pdf=AcroExch.Document
Simple as that.
