Download script or file from GitHub (thomasmaurer.ch)
Since a lot of people are starting to store their scripts and files in GitHub repositories, I often

get the question, how can I download a script or a file from a Git repository using PowerShell. There are a couple of ways to you can obviously do this. You could use git and do a git clone of the repository and then run the script. In many cases however you don't have git installed on the machine or it would be too much to clone the whole repo. So you can simply download the file or script from GitHub using PowerShell using the Invoke-WebRequest cmdlet.

Searching for PowerShell with CIM (jdhitsolutions.com)
Yesterday I shared a script that you could use to inventory systems for Windows PowerShell and

PowerShell 7 installations. This should work for most people who install PowerShell 7 with the provided installer. But, as has been pointed out more than once to me, this won't detect any side-loaded or out-of-band installations. I made reference to this in the previous article. I think the best you can do is search the hard drive instances of pwsh.exe. But we don't want to do a brute-force recursive directory search. Instead, I'm going to use Get-CimInstance.
