After months of waiting, leaks, speculation and rumors, Microsoft today from the BUILD conference in San Francisco announces that Windows 8.1 Preview is ready for download. The preview is primarily available from the Windows Store, but for those that cannot wait another second, Microsoft also made available a Windows 8.1 Preview ISO file that anyone can download and install when convenient.

Before installing the update (formerly known as Blue) in your primarily PC, I highly recommend to read my previous article How to upgrade Windows 8 to Preview, to Windows 8.1 RTM, because upgrading to the Preview will have some consequences later on when the time comes to install Windows 8.1 RTM.
