Allow or Prevent to Unblock a File to Stop the "Open File - Security Warning" Prompt
InformationThis will show you how to allow or prevent all users from being able to stop the Open File - Security Warning prompt by removing the unblock button and Always ask before opening this file check box for a downloaded or copied file from the internet or another computer.
The Open File - Security Warning prompt is a security measure in Vista, Windows 7, and Windows 8 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.
You will need to be logged in as an administrator to be able to do this tutorial.
NoteIf allowed, users will be able to unblock a file that has been downloaded or copied from the internet or another computer to your computer to no longer get the Open File - Security Warning prompt when a user opens or runs that specific file anymore.
If prevented, users will not be able to unblock a file that has been downloaded or copied from the internet or another computer to your computer, and will always get the Open File - Security Warning prompt when a user opens or runs that specific file.

I cant add the file: Enable_Unblock_Open_File_Security_Warning.reg to my registry.
I clicked on it and look in the registry and its not there.

Hello Cartel,
The enable REG file download removes the registry entry to allow getting the prompt. If you wanted to stop the prompt, then you would want to use the disable REG download instead.
Hope this helps,
Shawn

This tutorial is a life saver. Every time I tried to compute the MD5 Sum of a downloaded exe in W7 via context menu, it was triggering that security dialog. No fun if checking MD5 of 20 downloads! :)

Brink,
I tried this and found that it worked on all files. I have one file that triggers the security warning on computer startup or reboot. I would like to disable the security warning on that file only. Can it be done?

Hello Mariner,
This tutorial only allows or prevents the ability to unblock files to stop the security message. To actually unblock the file, you would use the tutorial below instead. :)
