SCCM-Powershell (maybe the worst)

# So this has to be run through SCCM. Both by packaging an "App" and calling powershell.exe to run the script, or by adding a script and running it.

# Variables
# So here's a webpage you want to scrape: 
$Source = "http://download.videolan.org/pub/videolan/vlc/last/win64/"

# This will run locally and give you the latest version of the win64.exe installer. Something like:  vlc-3.0.6-win64.exe
$Installer = ( Invoke-WebRequest $Source | fl * | Out-String -Stream | sls -Pattern 'win64.exe"' | select-object -First 1 | %{$_ -replace ".*href=.",""} | %{$_ -replace '".*',''} )
# But If you run that same line through SCCM your Installer Variable will be null. 

# Actually something like this would be the page source code: 
$SourceCode =  ( Invoke-WebRequest "$Source" )
# Again in SCCM this will be null, but running it locally will be fine. 

# What is weird is that this will produce the webpage both locally and in SCCM
Invoke-WebRequest "$Source" -OutFile "C:\example1.html"

# But this only works locally: 
Invoke-WebRequest "$Source" -OutVariable SourceCode
Add-content "C:\example2.html" -value $SourceCode

# So in SCCM example1.html will have code, but example2.html will be empty.
