These days everyone has a desktop computer, laptop, or at least a device such as a smartphone or tablet that they use to go online, send emails, and so on. And for the people who use a personal computer at home or at work then there is a very good chance that it is running Microsoft Windows. And if it’s a newer computer then there is a very good chance its running Windows 10 since new or has been upgraded to Windows 10 from Windows 7 or Windows 8.
