This theme from Gnome-Look will theme your MATE desktop to look just like the Luna theme in Windows XP. if that is what you want that is. Get the theme here: http://gnome-look.org/content/show.php/XPLuna?content=83797. This theme will not show up in the theme chooser for some reason, just go to the Customise section and select the XPLuna elements like window decorations and GTK theme individually. There is a download available here that contains a set of Windows XP icons. This will complete the theme. Then all you need is a Bliss.bmp wallpaper and you will have the whole Windows XP look down pat. Download the XPGnome theme here: http://xpgnome.en.uptodown.com/ubuntu. It is actually quite cool to use a Windows XP theme on Linux Mint, the Luna theme is quite good, if only the Windows 8 and Server 2012 theme was not so damn ugly.
There are some more lovely themes here if you want something different: http://www.securitronlinux.com/bejiitaswrath/lovely-gtk-themes-for-the-linux-mint-mate-desktop/.
This is the perfect wallpaper for your dual screen Windows XP styled Linux desktop: http://www.pathofdestruction.us/imageboard/displayimage.php?pid=120&fullsize=1.
