How can I disable the "Open File Security Warning" when I want to run downloaded executable files?

Adding these two registry entries prevent the error message "Open File Security Warning" that says "Do you want to run this file?" in Windows 7. As when disabling most security warnings, you should think it through before you do it.

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Attachments]
"SaveZoneInformation"=dword:00000001
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Associations]
"LowRiskFileTypes"=".zip;.rar;.nfo;.txt;.exe;.bat;.com;.cmd;.reg;.msi;.htm;.html;.gif;.bmp;.jpg;.avi;.mpg;.mpeg;.mov;.mp3;.m3u;.wav;"
