Microsoft Windows XP: Open File Security Warning - Unknown Publisher

After Installing IE7 (Internet Explorer 7), when I click on any batch files/exe files/vbs files on my local network, I got an warning messages that says:

"Open File - Security Warning"
Unknown Publisher
Would you like to run the file?

I have to spent an hour searching on the Internet to disable that stupid warning.

I have tried to avoid doing any of those "automatic updates" just because of these dumb features Microsoft suddenly decided to add to the operating system. But sometimes because the threats were immanent (e.g. when there was a security hole in the iframe) and sometimes because I wanted new features (e.g. IE7), I have to use their updates. Their updates are bad.

What they are trying to do is to push the security burden on the users instead of handling it themselves. Adding a thousand million warnings, so the users meddle around with their settings, inadvertently lowering the security settings unnecessarily in order to avoid this kind of warnings. When I searched the net, I saw some users tried to lower the "Internet security settings"  to the lowest in order to avoid this warning. That's how Microsoft make their products "look" more secured but in reality is more "unsecured".

Here's a way to disable this warning:
In Internet Explorer, click tools - Options
Under security settings, select "Intranet zone"
Click the "Sites" button, Uncheck the box that says "Automatically detect intranet network".
Checked the "Include all network paths (UNCs).
Click OK

To me it looks like a bug, it seems IE7 failed to automatically detect intranet network...
