Transform Windows 7 Into iOS 5 With iOS Skin Pack

When installing this transformation pack, you will be presented with the option to install the UXTheme Patch, DLL files and other extra items (e.g. wallpaper, visual styles, etc). You may select all or some of these options to continue. For example, you may not be interested in installing a screensaver, wallpaper, etc from the pack. To uncheck these items, expand the File and Extras options to deselect items. When done, click Install to begin the installation process

This will install all required components of the skin pack. Once installation is complete, reboot the system to get the iOS style look for your Windows 7 desktop.
