Many modern computers are capable of supporting the 64-bit version of Windows 7.
Previous versions of Windows have been available with a 64-bit version of the operating system, but Windows 7 is the first version that packages both versions of the OS together. Users have the option to install either version once they purchase the software. Most modern computers can run either version, but before installing the 64-bit version of Windows 7, you must first ensure that your computer's processor can handle it.
Instructions
Windows 7 and Windows Vista
1. Click the Windows "Start" button and click "Control Panel."
2. Enter the phrase "Performance Information and Tools" into the search box at the top-right side of the window and click on the returned result. A new window will open that shows you a rating of your computer's performance and other information.
3. Click "View and print detailed performance and system information" on the right side of the window below the ratings information if you are currently using the 32-bit version of Windows 7. If you are using Windows Vista, click "View and print details."
4. Scroll down the page until you see the System Information section. Look for the entry that says "64-bit Capable." If the entry says "Yes," then you can install and use Windows 7 64-bit. Otherwise you cannot.
Windows XP
5. Click "Start" and right-click "My Computer."
6. Select "Properties" from the right-click menu.
7. Look for "x64 Edition" under the System section of the window. If you see this entry, then the computer can run the 64-bit version of Windows 7. If you don;t see this entry, there is still a possibility that your computer can use the 64-bit version--check Upgrade Advisor (http://go.Microsoft.com/fwlink/?linkid=160680) for information on upgrading from Windows XP to Windows 7.
