Comparing different Get-ChildItem results

Hi Guys,

Hopefully you can help me. I'm getting close but don't get the result I want.

The idea is that is want to compare several locations (registry/filesystem) before and after.

When I run Get-ChilItem apart, the result is visible, but when I want to automate this in a loop, nothing is visible. Maybe it's really easy for you guys ;-)

This is the code I have now:

[EDIT] I thought i got it...but the results are not what I changed in registry :-S

$AmountOfRegistryLocations = $RegistryLocations.Count
# Count the amount registry locations
$AmountOfFilesystemLocations = $FilesystemLocations.Count
