The Scary Anatomy of a Microsoft License Fraud

Note: While this was originally posted around the Christmas of 2018, and some company or seller names might not be relevant as scammers come and go, the principles in this blog post seem to be valid since early 2000s to probably until 2038 (when the Internet ends due to the Epochalypse).

In this post, I describe how you can figure out if IE11 (Internet Explorer 11) has jumped in the compatibility mode. You run into this requirement every now and then, when trying to figure out some SharePoint browser compatibility mess-up.
