That's actually not how that works at all. Windows *does* in fact rely on the filename extension to determine the file type, but starting in Windows 95 they set it to hide the extension for known file types by default, presumably because extensions were too confusing for novice users. But the extension is still there and still counts for the OS's purposes, even though it's not displayed - so what malevolent parties will do is name a file e.g. InnocentDocument.txt.exe in the knowledge that this will display to the majority of users (and especially the novice ones) as InnocentDocument.txt even though it's actually an EXE and recognized as such by Windows. Real genius decision, that :/
