If you have touch input hardware that isn't specifically designed for Windows 8 or Windows 8.1, but displays the "Designed for Windows" logo for Windows 7, you'll experience touch responsiveness at least as good as it was on Windows 7. Because touch features of Windows 8 and Windows 8.1 require a higher degree of responsiveness and precision, touch PCs that were designed for Windows 8 or Windows 8.1 provide a much better experience typing on the touch keyboard and using certain features than those that were designed for Windows 7. For example, touchscreens that support fewer than five simultaneous touch points don't work with certain features and apps that are part of Windows 8 and Windows 8.1.
To use touch on system builder editions of Windows 8 or Windows 8.1, you need hardware that is certified for Windows 8 or Windows 8.1.
