64-bit Support

If you’ve gone PC shopping lately, you’ve probably noticed more computers with 64-bit processors, and you may have wondered what advantages they offer.

Put simply, a 64-bit PC can handle larger amounts of information than a 32-bit system. Since it can use more RAM—4 GB and up—a 64-bit computer can be more responsive when you're running lots of programs at once.

Whichever system you choose, Windows 7 is ready. All packaged retail editions of Windows 7 (except for Home Basic) include both 32- and 64-bit software.

Wondering whether a program or device works with your 64-bit PC? Look for products that carry the "Compatible with Windows 7" logo, which means they were tested on both 32- and 64-bit versions of Windows 7. Or visit the Windows 7 Compatibility Center to search a regularly updated list of programs and devices.

Picture of Control Panel Check Control Panel to see whether your PC is capable of running the 64-bit version of Windows 7.
