Windows 8.1, a free update to Windows 8, is coming later this year, but a pre-release version is available for you to try now.

Windows 8.1 Preview
and Windows RT 8.1 Preview both provide noticeable improvements with personalization, search, apps, the Windows Store, cloud connectivity, and other features. Microsoft, however, cautions that only experienced PC users should install the previews.

Previews, after all, aren't finished products. Although they're supposedly stable and thoroughly-tested, your system could crash, so installing pre-release software on your primary home or business PC is seldom a good idea.

Furthermore, if you're running Windows 8 RT, you won't be able to go back after you install Windows RT 8.1 Preview. You will eventually be able to upgrade to the final version of Windows RT 8.1, but you'll be stuck running the preview edition for the time being.

Depending on which version of Windows your computer or tablet is currently running, there are two ways to install the Windows 8.1 previews: as downloads from the Windows Store or by using an ISO image.

If your computer is currently running Windows 8, Microsoft recommends downloading the preview directly from the Windows Store. In fact, if you're running Windows RT, you can only obtain the preview from the Windows Store.

For those whose PCs use Windows 8 Pro or Windows 8 Enterprise, the update can also be installed using an ISO image. Installing via the Windows Store, however, eliminates the need for a license key. You'll need a key if you use the ISO image, but one is available once you logon to the Windows 8.1 Preview download page with a valid Windows account.

If you have Windows 8 Pro with Media Center, you can keep Windows Media Center providing you download the preview through the Windows Store. If you install the update using the ISO file, Windows Media will be removed and you'll need to reinstall it with your original Windows 8 Pro pack or Windows 8 Media Center Pack product key.

Uninstalling Windows 8.1 Preview isn't supported regardless of the installation method. If your PC came with Windows 8, using PC refresh might get you back to the original OS version, but it's not a sure thing. Your personal files won't be affected, but you'll have to reinstall software and apps that didn't come pre-installed when you unboxed your PC.

If your computer was running Windows XP, Windows Vista, or Windows 7 before the 8.1 upgrade, you'll need to reinstall the original operating system and applications using recovery or installation media. Not all computers come with these disks and people often misplace them, so be sure you have them before attempting the upgrade.

If you don't have recovery media, consider purchasing a product like True Image 2013 by Acronis that will let you create a recovery image of your PC before you install the upgrade. The image, which can be accessed using a bootable CD or thumb drive, can be stored in a special partition on the local hard drive or on an external USB hard drive.

If you have a PC with a 200-300 gigabytes of free hard disk space, 4 or more gigs of RAM, and an Intel Core i5 or Core i7 processor (or AMD equivalent), consider installing Windows 8.1 Preview as a virtual machine using free Oracle Virtual Box. This strategy will let you to test drive Windows 8.1 Preview without affecting your computer's current configuration.

Is the upgrade worth the trouble? Among other things, Windows 8.1 Preview lets you boot directly to the desktop and puts a start button back on the task bar. If you don't have a touch screen, Windows 7 is still easier to use, but the overall Windows 8 user experience has been improved.

Be forewarned, however, that to logon to a computer running Windows 8.1 Preview, you must use a free Microsoft account, not a local account. Microsoft says the option to create a local account will be made available at the final release of Windows 8.1.

Windows 8.1 Preview and Windows RT 8.1 Preview are both free. For more information, visit Windows 8.1 Preview of
