Step 1: Setting Background
To save the picture, right click on it and select save.
Go to Control Panel\Appearance and Personalization\Personalization then click on the background tab and set the image you saved as the background, if the background image doesn't fit your screen, select stretch then click ok.
Your desktop should now have this as the background.
Step 2: Removing Icon Names
1) Open Character Map, scroll down and select a blank character in the grid, click on the Select button, and click on the Copy button. (see screen shot above)
2)Right click on a icon on the desktop that you want to hide the text of, click on Rename, right click inside the rename box, click on Paste, and press enter.
NOTE: If you get a message that a another icon already has the same name, then just repeat step 1 to select a different blank character and do step 2 again.
3)The text of the desktop icon will now be hidden. (see screenshot above)
4)Repeat the steps above for all other icons on the desktop.
Step 3: Hiding the Task Bar
You can access the task bar by moving your cursor to the bottom of the screen at any time.
Step 4: Moving the Icons
Hover your mouse over view so the pop out appears (like in the screen shot above).
Click on 'Align icons to grid' so the tick dissappears and click off it. You can now move the icons on screen anywhere and they won't be stuck in a grid system. Click on an icon and drag it into the box at the bottom, leave a small space bettween each app and don't over crowd it. It is also best if you move the recycle bin to the far right of the box
Step 5: Final Result
If you compare it to the real mac home screen (the other photo), they are incredibly similar and you can hardly tell the diffrence!
If you ever need to access the windows taskbar, just put your mouse at the very bottom of the screen and it should appear!

Step 6: Further Improvement
If you have photoshop, you can make your desktop look even more like a mac then it does already. Just leave the icons on the desktop in the dock at the bottom, then change your wallpaper to a blank colour (green is usually the best) then take a screen shot. Open the screen shot in photoshop then remove the background, so you just have the icons. Then flip the icons upside down, as if it were a reflection. Once you have done this, set the layer transparency to about 40% (or what ever looks good). The use the soft edged eraser tool to get the icons to fade out. Save the image then set it as your wallpaper. It should look similar to the screenshot above.
