If you use the default Windows desktop, chances are that you could use a “look and feel” overhaul. Apple’s OSX is widely considered to be cleaner, more intuitive, and more customizable. The following instructions will show you how to get that Mac look for your PC by installing some cool, free applications. Some of the instructions may be a tad advanced for some users, but give it a try.
Remove all unused shortcuts and icons from your desktop. Chances are you don’t need half of those junky shortcuts on your desktop. You have three options for them. 1: Move the ones you don’t need to the Recycle Bin. 2: Create a folder on your desktop for all of your shortcuts. 3: If you have descoerasuaphobia (fear of erasing desktop shortcuts) then let Windows decide for you with the Desktop Cleanup Wizard. Right-click on the desktop, select Arrange Icons By > Run Desktop Cleanup Wizard. This will get rid of shortcuts you haven’t used in a while. Or you can just right-click on your desktop and select arrange icons by and unclick show icons.

You should now have a completely clean desktop. Don’t be afraid. You can still access the My Computer, My Documents, and Recycle Bin standbys from Windows Explorer.

Two words: RKLauncher. (OK, one really.) RKLauncher (also called RKDock) is a free, Windows copycat of the animated Mac taskbar, or “dock.” You can download it here. RKDock comes with a pretty cool theme. If you want to make your dock look exactly like a Mac though, try RealDock for RKLaucher, a great clone of the Mac Dock appearance.

Hide the taskbar. It doesn’t make sense to have ObjectDock and the Windows taskbar. Right click a blank space in ObjectDock, go to the settings tab, select behavior then on the box with check marks select “Hide the Windows Taskbar”, and hit OK. This makes the taskbar disappear. You can also just move the taskbar to the front of the screen.\

Add Widgets.Widgets are desktop toys to entertain and to inform. Think of them like things you’d put on a real desk: a picture frame, a newspaper…a dancing hula girl. But they’re on your PC desktop, not your real desk. (You’ll get it once you see it.) They may be the most fun thing to happen to boring computers in a long time. Download free widgets from the Yahoo Widgets page. You’ll download a widget machine called Yahoo! Widget Engine(you can also download Konfabulator but more recent widgets will not work with it), which comes with widgets like a picture frame, analog clock, calendar, and weather display. You can get more widgets like RSS news feeds and a dancing hula girl from the widgets gallery. Yahoo! has also released an engine that can help you make your own widgets and is available here

Safari for Windows Just Get the new Safari 3 Beta, for Windows http://www.apple.com/safari/download/

Wallpaper Change your wallpaper to look like Mac OS X Tiger: here. Or you can get a high resolution wallpaper here which won’t make your computer mimic a mac desktop but will add a sense of style and a unique touch.

FlyakiteOSX One convenient item that can be used to enhance your Windows to Mac experience is if you have all the elements of Mac Emulation bundled in a package. FlyakiteOSX does just that.

WindowBlinds If you would like to make your Windows have buttons on the left side instead of the right, you can buy WindowBlinds. It comes with ObjectDesktop.

ShellWM A titlebar-only shell replacement. It lets you have the buttons on the left for free. You’ll want to download this theme.

Mouse Pointers. For the full effect, download a new set of mouse pointers. Save these to your computer (preferably in C:\WINDOWS\Cursors. It may be a good idea to make a folder within this for easier setup.) To setup these cursors, choose Mouse from the Control Panel, click the Pointers tab, and set your new pointers appropriately.

Even these customization looks much more better than older windows. It may make your computer slow. Some of the contents in widgets needs internet connection and Safari for windows is still in beta. So beware of these drawbacks. But you can restore back to windows desktop at any time
