What if I can't choose the Upgrade option?
Some versions of Windows can't be upgraded with the installation disc you're trying to use. For example, you can't upgrade a 32-bit version of Windows to a 64-bit version, or upgrade from a higher edition of Windows, such as Windows Vista Ultimate, to a lower edition, such as Windows 7 Home Premium. If this is the case, you'll need to use the Custom option during installation.
However, unlike Upgrade, the Custom option does not preserve your files, settings, or programs. You'll need to back up your files and settings before installing Windows 7, restore them after installation is complete—and you'll also need to reinstall your programs using the original installation discs or files. For a step-by-step tutorial on how to perform a custom installation, see Upgrading from Windows Vista to Windows 7 (custom installation).
•To upgrade an earlier operating system than Windows XP (for example, Windows 95 or Windows 2000), you'll need to purchase a full version of Windows 7 and perform a custom installation.
•In the European Union (including Croatia and Switzerland) and Korea, Microsoft will release Windows 7 editions that don't include certain features such as Windows Media Player and Windows Media Center. Upgrading to these editions requires a custom installation.
•Upgrading Windows Vista in one language to Windows 7 in a different language requires a custom installation.
32-bit or 64-bit: Which version of Windows 7 to install?
If you're running a 32-bit version of Windows Vista, you can only upgrade to a 32-bit version of Windows 7. Similarly, if you are running a 64-bit version of Windows Vista, you can only upgrade to a 64-bit version of Windows 7. Otherwise, you'll need to use the Custom option to install Windows 7.
Both 32-bit and 64-bit installation discs are included in the Windows 7 package. 64-bit operating systems can handle large amounts of memory—typically 4 gigabytes (GB) of random access memory (RAM) or more—more efficiently than 32-bit operating systems. However, not all computers are 64-bit capable. For more information, see 32-bit and 64-bit Windows: frequently asked questions.
To find out which Windows 7 installation disc you can use, do the following:
1.Open Performance Information and Tools by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking Performance Information and Tools.
2.Click View and print details.
3.Under System, you can see what type of operating system you're currently running next to System type, and, next to 64-bit capable, whether you can run a 64-bit version of Windows.
If your computer is already running a 64-bit version of Windows, you won't see the 64-bit capable listing.
Depending on your hardware and your current edition of Windows Vista, you can use the Upgrade option during Windows 7 installation to upgrade from Windows Vista to a corresponding or higher edition of Windows 7.
Upgrading is the most convenient way to get Windows 7 on your computer, because it keeps your files, settings, and programs from Windows Vista in place.
Step 2: Installing Windows 7
When you upgrade to Windows 7, you keep your files, settings, and programs from Windows Vista.
The options for Windows 7 installation
Before you begin
•Be sure your computer is running either Service Pack 1 or Service Pack 2 for Windows Vista. For more information, see the Windows Vista service packs webpage on the Microsoft website.
•Connect your PC to the Internet so you can get installation updates during the installation process. (If you don’t have an Internet connection, you can still install Windows 7.)
•Update your antivirus program, run it, and then turn it off. After you install Windows 7, remember to turn the antivirus program back on, or install new antivirus software that works with Windows 7.
•If you have a Windows 7 installation package, choose either the 32-bit or 64-bit Windows 7 installation disc, depending on which version of Windows Vista you're currently running.
•Find your 25-character Windows product key. You can find it on the installation disc holder inside the Windows package—or in a confirmation e‑mail if you purchased and downloaded Windows 7 online.
•If you use a fingerprint reader or other biometric device to log on to your computer, make sure you write down your password before upgrading. You must log on by typing your user name and password the first time that you use Windows after upgrading.
Some programs such as Windows Mail and Outlook Express are no longer included in Windows 7. If you used Windows Mail or Outlook Express as your e‑mail program, after you've finished installing Windows 7, you’ll need to install a new e‑mail program to read your messages or to send and receive e‑mail. For more information about Windows Live Mail and instructions for importing your e‑mail, contacts, and calendar, see Importing your e‑mail, messages, contacts, and calendar into Windows Live Mail.
