Windows has only one major advantage over Linux, it comes preinstalled with all required hardware support.

Both installing Windows and installing Linux can be difficult for most people. I have done both professionally and when installing Windows I have encountered frequently more serious problems, which required much more time to solve than the problems encountered when installing Linux.

For those who have someone else to install and configure Linux, it is at least as easy to use as Windows.

My parents, more than 80-years old, have used for many years Linux without any problems and they have no idea what Linux is, they just know the applications that they are using for viewing and editing documents, e-mail, Internet browsing, music or movies listening or watching, TV watching or recording (with TV tuner) and so on.
