MacOSX Lion 10.7 is fresh, but the fanboy of WIndows has already made a tool for you to easily convert your Windows box into a nice Lion 🙂
This tool will backup everything before installation, so you can go back if you want. The author suggests that you should make a backup yourself and turn off UAC before installation.
You can select or deselect various component of the package
WHen you have finished the installation, reboot the system
And, you have a fresh new look of Mac OSX Lion on your Windows box
and the exciting desktop
You can download the tool free from here: http://hameddanger.deviantart.com/#/d3bg7fq
