the settings from Windows operating system cannot be applied to a computer with the
Mac operating system and vice versa.
2. There are some features that are available only on certain versions of Windows operating
system. For example, triggering Cortana through a mouse button press is a feature
available only on Windows 10 and not on Windows 7 and 8 as Cortana is not available

unsupported operating systems.

If you're not sure if the problem is a hardware or software issue, try switching the buttons in the
settings (left click becomes right click and right click becomes left click). If the problem moves to
the new button it is a software setting or application issue and hardware troubleshooting
cannot resolve it. If the problem stays with the same button it is a hardware issue.
