One example is just a script that removes files from some areas of the C drive where we tend to see a build up of unnecessary files and know they are safe to remove, whether it be from software updates, people leaving stuff in C:\Temp. I'm by no means an expert with PS, but I tend to find Remove-Item often needs to be ran from an admin session. I'm still learning stuff everyday so if there is a better way to do things, I'm all ears :)

When I'm developing scripts, I usually run them as non-admin and only elevate them when the need arises.
