Windows: Disable “Publisher Could Not Be Verified” Messages

Disable the warning message that says “The Publisher Could Not Be Verified” when you run certain files in Windows.

1. Click Start > Run and type gpedit.msc. Click OK

2. Go to User Configuration > Administrative Templates > Windows Components > Attachment Manager

3. Open the Inclusion list for moderate risk file types setting.

4. Set the policy to Enabled, then add “*.exe;” or whatever the file extension you are using to the Specify high risk extensions box.

Inclusion list for high risk file types policy

This should disable the “Publisher Could Not Be Verified” messages from appearing for that file type in the future.

    After applying security patch, when I run exe file I get this “Publisher could not be verified message”. After this work around, the problem disappeared.
    Great tip

    Hi. I tried to run the gpedit.msc but windows cannot find gpedit.msc.
    Is there any other option to find this? I use windows 7

    Seems you need a semi-colon at the end (and between extensions) for this to work now.

    Thanks for the tip. Worked like a charm. Along with disabling System Tray tooltips, this is a great step toward making Windows a less nagging OS.

    Marcel and David, what the deuce are you two on about? This nanny feature was in Windows long before anything remotely similar showed up in OS X. And, unlike Windows, the OS X warning (which only applies to downloads) only appears once. So, quit trolling.

    As it stands, OS X does far less nagging than Windows ever does. You want an OS to hold your hand? How about one that tells you something completely inane like the system tray balloons do? Ha!

    I’m sick and tired of this patronizing attitude the PC side of things has toward Mac users. Good heavens, we’re running a UNIX based OS that can be every bit as complex and convoluted as you could dream of. Why you people pride yourselves on difficulty and inconvenience is beyond me, but to imply that someone is inferior by their choice of OS is downright low.
