Find which Hot-Fixes (KBs) you have installed in Microsoft Dynamics AX

With the new Microsoft Dynamics AX it is not so straight forward to determine the hot-fixes (KBs) you may have installed in your environments. So, I have created the following PowerShell script to list the fixes you have in your packages folder. Please provide me with feedback on improvement suggestions or if you find any issues with the script.
