Q: Why Windows 7?

A: Microsoft says that Windows 7 is the "seventh" major Windows version, which it isn't, but whatever. Adding to the mystery, the Windows 7 version number will actually be 6.1, the same as Windows Server 2008.

Q:How do I get Windows 7?

A:Use the download link at the home page to begin download. If you have a netbook or other PC that doesn't have a DVD drive, downloading and run on a removable device. For more information about how to get Windows 7 in your country or region, download our eBook

Q:Will my software and devices work with Windows 7?

A:Almost all programs compatible with Windows Vista, and the majority of Windows XP programs, run well in Windows 7. If a program written for an earlier version of Windows doesn't run correctly, you can try changing the compatibility settings for the program. For more information, see Make older programs run in this version of Windows.

Many devices that work with Windows XP or Windows Vista will also work with Windows 7. To find out if a program or device will work with Windows 7, visit the Windows Compatibility Center.

Q: Will I lose files, programs, or settings when I install Windows 7?

A: An upgrade installation of Windows 7 will keep your files, programs, and settings in place. A custom (clean) installation doesn't preserve your files, programs, or settings. If you plan to do a custom installation of Windows 7, be sure to back up your files and other information first. You'll also need to manually reinstall your programs. For more information, see Installing and reinstalling Windows 7.

Q: How can I upgrade from one edition of Windows 7 to another edition of Windows 7?

A: You can add more features to Windows 7 by upgrading to another edition (for example, upgrading from Windows 7 Starter to Windows 7 Home Premium). You can buy an upgrade key either in a retail store or online (where available), then use Windows Anytime Upgrade to perform the upgrade. For more information, see Upgrade to another edition of Windows 7 by using Windows Anytime Upgrade.

Q: Can I format my hard drive, and then install Windows 7?

A: If you purchase the full version of Windows 7, you can format your hard drive, and then install Windows 7. If you purchase the upgrade version of Windows 7 and want to format your hard drive, you'll need to start (or boot) your computer from the Windows 7 installation disc or a USB flash drive, and then perform a custom installation. You can click Drive options (advanced), and then format your hard drive. Don't use a program from another software manufacturer to format your hard drive before installing Windows 7. If you are using upgrade media and format the drive before starting the installation process, you won't be able to use the upgrade product key to activate Windows 7. For more information, see Installing and reinstalling Windows 7.

Q: What is the difference between 32-bit and 64-bit?

A: 64-bit operating systems can use more RAM—4 GB and up—than 32-bit operating systems. That can make them more responsive when you're running lots of programs at once. All packaged retail editions of Windows 7 (except for Home Basic) include both 32-bit and 64-bit installation discs. To find out if your PC is capable of running a 64-bit version of Windows, download and install the Windows 7 Upgrade Advisor.

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

A: If your PC has a 64 bit-capable processor (CPU), you can install a 64-bit version of Windows 7, even if you are currently running a 32-bit version. However, to install a 64-bit version of Windows 7 on a computer already running a 32-bit version, you'll need to back up your files and choose the Custom option during installation. Then, you'll need to restore your files and reinstall your programs. For more information see 32-bit and 64-bit Windows: frequently asked questions.
