Lets Do It Windows 8 Way.

Windows 8 beta is about to release in February 2012 if all goes well, but if you cant wait any much more and is also fed up from your Windows 7 look then why not to change your windows 7 look and give it the feel of Windows 8.
Here are some steps which you will have to do to get Windows 8 look.

1. First of all create a restore point, you can do it by clicking on start menu => All Programs => Accessories => System Tools and click on restore point. (I recommend to do it before any installation, in case something goes wrong, so you can restore back from here.)
2. Go to Your system properties. You can do it by clicking on start menu and then right click on My Computer and click Properties.
3. In System menu, check the system type that whether it is 23-bit or 64-bit.
4. Go to Windows 7 Transformation.
5. Scroll down and click on your required download (32-bit or 64-bit).
6. Extract the downloaded file and click Next.
7. Accept the agreement and click next.
8. Select Advance Installation and uncheck all the 3 boxes, click Next.
9. Press Install.
10. Restart your computer.

Now you will have Windows 8 look. I recommend to keep the taskbar on right, because at the bottom the clock is bugged. you can do it by dragging taskbar to the right.
