Windows smart screen and signed apps

[zylesea]

Here's a rather Windows related issue...
When i compile a program for Windows, save it on usb stick and put that stick to a Windows computer it just runs that program w/o complaining. But put on my website and trying to download Chrome (or is it Windows itself? or McAfee?) tells me it's a suspicious download. If I ignore that warning and doubleclick the icon the Win 8 smart screen also tries to convince me that this application is not trustful and by default refuses to run the program. Is that due a lack of code signing? But if so, why does it run w/o complaining from the usb drive? How does Windows discern the downloaded version from the non downloaded version (even non packed)..? Anyone an idea?

Yes, you'll get these warnings because Hollywood generated executables are not code-signed. To code-sign executables you need to sign up with Microsoft and pay a yearly fee which starts at a whopping $99 AFAIR. It is possible to code-sign Hollywood executables using Microsoft tools. So if you have purchased a certificate, you can use Microsoft tools to apply the certificate to executables generated by Hollywood and the warning will go away, see here:

These warnings definitely come from the OS itself, not from Chrome, although Chrome also has its own filter AFAIK. I don't know how Windows tracks which files were downloaded from the Internet but it's certainly not black magic to do this.
