How to Disable the "Open File Security Warning" in Windows
Information
This will show you how to enable or disable XP, Vista, or Windows 7 prompting you with the Open File Security Warning when you open or run a downloaded or copied file from the internet or another computer on your computer.
Warning
The Open File - Security Warning prompt is a security measure in Windows 7 and Vista to ask for your permission (like UAC) before allowing a downloaded or copied file from the internet or another computer to be opened or run on your computer.
Disabling Open File - Security Warning will reduce the security level of Windows, and place your computer at a higher risk of being infected by malware.
Disable at your own risk if you no longer want to have a Open File - Security Warning.

This is how it looks when I hit Reply to the thread.

Another way is to create an environment variable called SEE_MASK_NOZONECHECKS and give it a value of 1. You can do this from an elevated command prompt: setx SEE_MASK_NOZONECHECKS 1
See next post for information about dangers involved.
this broke my computer, now all my browsers when downloading block the downloads and I cant change the security settings.
if the OP worded this better my computer would work, what is zone checking? who knows, all I know is I can no longer download anything since installing something from here must be a virus, all my downloads are blocked.
someone should virus scan these files because they broke my computer.
