No, I don't get your point. IF you have problems of security on that level, then it is user error, not OS error. Here's my documented proof:
Learn how to do what? Double-click my way through a complicated gui with buttons, text fields, and listboxes? My XP Pro box is about as secure as it can get... which varies day to day thanks to all the vulns found and posted courtesy of MicroSoft® OS's being flimsy and not well-thought out in terms of actually being "secure" in many aspects. Enabling NetBios over TCP/IP by default... Remote Desktop by default... UPnP by default... filesharing by default... DCOM and RPC services waiting to be exploited -on by default... IE MS-ITS: URL handler vulns (not conting a zillion others + some)... yada yada yada you get the point.
