These aren't really bugs, but, in my opinion, the following icons should be XPized: - WMV file icon, when Windows Media Player 10 is Installed. - Internet Options icon in the Control Panel (is Vista-like, if IE7 is installed) - Software Explorers Icon in Control Panel (Windows Defender related) - the CDF icon dosen't exist anymore (due to IE7): I suggest icon-file association like you did with PDFs, PHPs, etc.; for legacy purposes (I know, this one is pushing it too hard )
