Another method is:
How to disable the “Unknown Publisher” security warning when running an application after installing Windows XP SP2.
XP PRO SP2 Instructions
1) Start menu > Run gpedit.msc
2) Go to Local Computer Policy User Configuration
3) Administrative Templates Windows Components
4) Attachment Manager and enable “Default risk level for file attachments”
5) Enable “Inclusion list for low file types” and add to this list the file extensions that you want to open without triggering this crap.
XP HOME SP2 Instructions
Copy and paste the following bolded text below into a notepad document.
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Associations]
"DefaultFileTypeRisk"=dword:00001807
"LowRiskFileTypes"=".exe"
From the file menu chose “save as” and save the txt documents as DefaultFileTypeRisk.reg
Change “save as type” to *.* and save the file.
Once this file is imported it will allow the execution of all unknown publisher “.exe” files to run automatically without being prompted with a security warning. If the file being launched is not a .exe file please change the follow line above "LowRiskFileTypes"=".???" by replacing the area where the question marks are with the appropriate file extension of your liking.
Then reboot the computer.
