In Microsoft IT, we wanted to remove the blocked file types to have users have the freedom to upload the necessary files they need. Note: We also have Forefront for SharePoint running on our farms so we are less concerned for any sort of virus/malware on our machines.

Here is the script I created to remove all the Blocked File types on your farm. Let me know if you have any questions. Thanks!
