Microsoft is showing off all the new features of Windows 8.1 today, but curious users can download the 8.1 Preview right now. Here's what you need to know.
The preview is currently only available as an update installer, but Microsoft says that an ISO version will be available within the next day.
Note that if you upgrade to the preview now, you'll have to reinstall all your apps -- both Modern apps and desktop apps -- when you upgrade from the preview to the final version. So, we recommend downloading the ISO and installing it in a virtual machine or a separate partition to try it out. Hit the link below to check it out.
