Windows 8 Release Preview should work with the same devices and programs that work with Windows 7. In some cases, the device or program might require an update or you might need to uninstall some programs, and then reinstall them after installing Windows 8 Release Preview. The Windows 8 Release Preview Setup program will scan your PC to determine what's compatible and provide a report that you can save or print. Make sure your devices are connected to your PC and turned on before you run the Setup program. If you want compatibility info for a specific device or program, see the Windows 8 Release Preview Compatibility Center.
