It is worth noting that the installation of the Release Preview hasn’t changed much since the launch of the Consumer Preview. You will notice that when you boot your PC, the setup kicks up pretty quick; the betta fish image is not longer part of the startup screen, now the word “Windows” is the only things that appears together loading ring animation. And other few cosmetic changes that you’ll see during the installation.


1. Download a copy of Windows 8 and grab the product key — this time around you are going to need it –. Also make sure that you download the correct version (32-bit or 64-bit).

2. Make a bootable installation media, the simplest way to do this is by using the Windows 7 USB/DVD Download Tool from Microsoft. If you like challenges, you can try creating a Windows 8 bootable USB drive manually using the command prompt (see instructions). Once you done with step #2, now we can actually dive in to the installation process.

3. Check that your system has the BIOS configured to boot from USB or DVD, depending on how you want to do the installation. To do this refer to your PC’s manufacture manual as there are many different ways to change the BIOS configuration.

4. Boot your computer with the Windows 8 bootable media, the new Windows splash screen will appear and it will take you right to the Windows Setup screen.
