But I AM the administrator

A while back I was helping a co-worker with a project where the customer needed to automate a lot of minor Windows configuration steps on some Windows IoT server appliances. One of the tasks was to make it possible to disable Windows Firewall, because even an administrator was greeted with the message "For your security, some settings are managed by your system administrator" and the option to change firewall settings was disabled.

Image Comparison

I recently came across a couple of blog posts on image comparison algorithms shared by Dr. Neal Krawetz. One of them, titled "Kind Of Like That", describes the "dHash" algorithm which generates a perceptual hash based on gradients in the image. With more than 200k family photos to wrangle, I wrote up a PowerShell implementation to find similar images and it works surprisingly well!
