[QUOTE=Kerry56;2691508]You should be aware that if you install the 8.1 preview, you won’t be able to upgrade to the release version later without a full re-install of the operating system and all your programs.
The one exception that Microsoft has given is if you using Windows RT 8.1. Windows RT users cannot revert back to the original operating system after installing 8.1, but can update to the full release when it comes out.
Therefore, if you just want to try out 8.1, you should run it in a VM.[/QUOTE]
I registered to this forum just to let you know that actually you CAN upgrade from Windows 8.1 Preview to the final release when it does come out. According to the Windows 8.1 Preview FAQ at http://windows.microsoft.com/en-us/windows-8/preview-faq:
“Additionally, you’ll also need your Windows 8 product key when you update to the final edition of Windows 8.1 from the preview.”
That implies there will be an update from the preview version to the final edition.
