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