Does anyone know how to disable the unknown publisher security warning when running an application in Windows Xp Home? It's pretty annoying to have to click run everytime...

I have tried:

Run gpedit.msc, and go to Local Computer Policy->User Configuration->Administrative Templates->Windows Components->Attachment Manager and enable "Default risk level for file attachments", and then enable "Inclusion list for low risk file types" and add to this list the file extensions that you want to open without triggering this crap.

But this file 'gpedit.msc' doest not exist on my computer, i checked system32 folder also =/ maybe its for xp pro
