The Broken Design of Microsoft's "Fix it" Tool
$luggo writes "Curious about MS Fix It, I recently went hunting in the MS knowledge base for articles that provide the new EZ-button. After locating on few, I decided to click the button to download the Microsoft Installer package containing the executable and/or files that automatically enable the DVD Library feature in Windows Vista Home Premium and Ultimate — on my XP Media Center. 'Surely, MS will use some scripting, HTTP User-Agent sniffing, or even Genuine Windows validation to verify that I am running Vista,' I thought. It did not and I canceled the download when I received the prompt to save the file. So, I wonder: is there a Fix-it for Fix it? Because I can easily imagine someone doing what I did without scrolling to the bottom of the KB article and verifying that the article applies to their OS/version. This is a great example poor design. Why not simply use the download approach that other articles / fixes / service packs use, whereby the user must select the appropriate OS?"
User-Agent "sniffing" is a bad approach under any circumstances - it's too easy, not to mention common, to fake. And since all script-based approaches I am aware of rely on User-Agent detection, they would be effectively broken as well.
If I were doing it, I would put the OS detection in the setup EXE itself. That way, the setup program could *authoritatively* determine what OS was in use, and block installation onto any invalid systems. But we may never know since you didn't finish the download and give it a shot. ;)
