How to disable "Open file - Security warning" in Windows XP?

The Open File Security Warning dialog box appears when opening files after an upgrade of Windows XP with the SP2 update. This function was added in the SP2 update to improve Window's security. The warning enables you to protect your computer from harmful files executing without your consent. Unfortunately, the constant pop up of the warning quickly becomes an aggravation.

Method 1

Basically this prevents scheduled scripts to run on the system. If you are absolutely sure you want to allow the execution without confirmation, you can add the server which shares the executable file(s) in the Internet Explorer’s Local Intranet Zone. The systax is file://servername not http://servername. Note that this action compromises the system security.

    • Click Start, Run and type INETCPL.CPL
    • Select the Security tab, Trusted sites
    • Click Sites button
    • Add the IP address of the remote computer to the list (You can also add the network shares to the Local Intranet zone.)
    • Uncheck Require server verification (https:) for all sites in this zone and click Close
    • Click OK, OK and close the dialog

Method 2

To disable the warning start the Group Policy Editor (Start > Run, type gpedit.msc and press OK) and go to:

User Configuration > Administrative Templates > Windows Components > Attachment Manager- then set Inclusion list for low file types to Enabled and enter the file types you don't want to be warned about in

the box (for example: .exe).
