Which Windows 8 version is right for me?

There are two versions to choose from: Windows 8 and Windows 8 Pro. Windows 8 comes with everything you need to connect, share, work and play — even for power users. Windows 8 Pro adds enhanced features for people who need to connect easily to company networks, access remote files, encrypt sensitive data and perform other more advanced tasks

What kinds of devices come with Windows 8 already installed?

A whole new family of desktops, laptops, tablets and other devices — many with touch-screen capabilities — come preloaded with Windows 8. They're faster and more energy-efficient than previous models, while the portable and ultraportable devices are thinner, lighter and have better performance and battery life.

Can I upgrade my PC from an older version of Windows to Windows 8?

Yes. Your upgrade experience will depend on what version of Windows you currently have. For example, if your PC is running Windows 7 Home Basic or Home Premium, your files, programs and settings will easily transfer to Windows 8. If your PC is running Windows XP, Windows Vista, Windows 7 Professional or Windows 7 Ultimate, you'll need to reinstall your programs. Some features (like those that support touch screen) may require a new PC.

To find out if your PC is ready for Windows 8, go to www.windows.com/upgradeassistant and download Windows 8 Upgrade Assistant, which will provide you with a full compatibility report.

How can I tell if my devices and apps will work with Windows 8?

Windows 8 generally works with the same peripheral devices and apps that work with Windows 7. In some cases, a device or program might require an update, or you might need to uninstall some apps, and then reinstall them after you upgrade to Windows 8.

The best way to tell if your apps and devices will work before you upgrade is to run Windows 8 Upgrade Assistant, a free program that scans your current hardware, apps and devices for compatibility. Make sure all the devices that you need to work with your PC, like printers and monitors, are connected to your PC and turned on before you run Upgrade Assistant.

After Upgrade Assistant scans your PC to determine what's compatible, it provides a compatibility report that lists any issues that you might need to address when you upgrade. You can save or print this report to use later.

If you'd like to look up compatibility info for a specific device or program, you can search for it in the Windows Compatibility Center.

What settings, apps and files can I keep if I upgrade?

You can upgrade to Windows 8 from Windows 7, Windows Vista, Windows XP, Windows 8 Release Preview, Windows 8 Consumer Preview or Windows Developer Preview, but you might not be able to keep all of your files, apps and settings. The following table shows what you can keep during an upgrade, depending on the version of Windows you currently have running on your PC:

  • Upgrading from ...
  • Windows 8 Release Preview
  • Windows 8 Consumer Preview Windows Developer Preview

  • Windows XP
  • What you can keep

Can I upgrade from a 32-bit version of Windows to a 64-bit version of Windows 8?

If your PC has a 64 bit-capable processor (CPU) but is currently running a 32-bit version of Windows, you can install a 64-bit version of Windows 8, but you cannot do this as an online upgrade. You'll need to download the Upgrade Assistant to a DVD or a bootable USB device and install Windows 8 from there. You also won't be able to keep any files, settings or apps when you upgrade from a 32-bit to a 64-bit version.

Can I upgrade from an operating system that's older than Windows XP?

You can upgrade online or by using a DVD that you can purchase from participating retail stores to upgrade a PC running Windows XP, Windows Vista, Windows 7, Windows Developer Preview, Windows 8 Consumer Preview or Windows 8 Release Preview. If you want to upgrade from an earlier Windows operating system than Windows XP (for example, Windows 95 or Windows 2000), you'll need to purchase the Windows 8 System Builder from your nearest system builder or participating retailer. You won't be able to keep any files, settings or apps when you install the new operating system.

If I upgrade and "keep nothing," how can I restore my files after the upgrade?

If you're running Windows Developer Preview or Windows 8 Consumer Preview when you upgrade, or if you choose the option to "keep nothing" when you upgrade, your files won't come with you to Windows 8. However, you might still be able to copy your files over after you upgrade. If you don't reformat your hard drive during installation, your files will be saved to the Windows.old folder, where you can retrieve them after the upgrade.

If I change my mind, can I uninstall Windows 8 and go back to a previous version of Windows?

Yes, but to go back to your previous version of Windows you'll need to format your hard drive and then reinstall the previous version of Windows from the recovery or installation media that came with your PC. Typically, this is on a DVD. If you don't have recovery media, you might be able to create it from a recovery partition on your PC using software provided by your PC manufacturer. Check the support section of your PC manufacturer's website for more info. After you install Windows 8, you won't be able to use the recovery partition on your PC to go back to your previous version of Windows.

Can I change my language when I upgrade?

The easiest way to change your language is to upgrade to the same language you currently have on your PC, keep your apps, settings and files, and then add a new language afterwards. If you switch from one language to another during the upgrade, you won't be able to keep your apps or settings.
