Which Windows 8 edition is right for me?

Compared to Windows 7's seven different versions, Windows 8 has four major editions: Windows 8, Windows 8 Pro, Windows 8 Enterprise, and Windows RT.

As per the Windows Team blog,  Windows 8 is for regular consumers while Windows 8 Pro is designed to help tech enthusiasts and business/technical professionals.

Windows 8 Enterprise and Windows RT will not be available at retail outlets. Windows RT will come pre-installed on ARM-based tablets or PCs.

The RTM version of Windows 8 came out yesterday (on August 15th, same as India's Independence Day) and is available for MSDN & Technet subscribers. Microsoft plans to release Windows 8 for general availability on October 26, 2012

If you would like to take Windows 8 for a spin before making it your default OS, you can download the 90-day evaluation edition of Windows 8 Enterprise and try it out with Virtual Machine software like the free VMWare Player.
