Windows 8 developer preview installer is currently available for public download from the official Microsoft Windows website. If you like to get first hand experience on what is new in Windows 8, I strongly recommend you install it on a Virtual Machine rather than trying it on your primary computer.
There are several virtual machine applications available for you to try Windows 8 installation. I could not get Windows 8 to install on Windows Virtual PC and VMWare Player, but I had luck with VMWare Workstation and Oracle VM VirtualBox. I have given step by step instructions to install Windows 8 on VMWare Workstation in another post.

Click 'Next', which will take you to a screen to provide a name for this virtual machine and also to choose the Windows version you are installing.
Choose any name you are comfortable with. Select your operating system as 'Microsoft Windows'. In the dropdown list to choose the version, you will not find Windows 8, so choose 'Other Windows'.
(In future versions of Oracle VM Virtual Box, you will see Windows 8 as well as an option).
In the next step, you will choose the memory to be allocated for the Windows 8 virtual machine on the Oracle VM VirtualBox:
Recommended memory for 32-Bit Windows 8 is 1Gb and for 64-bit Windows 8, it is 2Gb.

Recommended hard disk size is 16Gb and 20Gb fo r32-bit and 64-bit respectively.
You may choose to dynamically grow the hard disk so that if you do a lot of work on your Windows 8, your hard disk will grow as you need.
You need to reconfirm your selections in the next few screens and you are almost done!
