Yes the Snow Leopard was out, and Windows 7 haven’t officially out but you can get your hands on the new Snow Leopard Theme for Windows 7 – Thanks to Redmond Pie
He has composed 3 different theme packs of Windows 7
Feel free to download the theme pack here
Note: this is only for Windows 7 with the theme pack, to install just double click the file after extract. Also keep in mind that the theme pack is a little bid different from a whole pack of wall papers. Since it can also manipulating the system notification sound, and icons. In this case the sound and the wallpaper has changed. You can change back to the default Windows by going to Sound on the bottom of the Personalization Panel
That’s it, and incase if you are wondering where is the wall paper saved exactly, you can also go to the “Desktop Background” and you will find your URL will be something like this.
