When you load up your friend’s computer with your favourite operating system, you may not be doing them any favours. You may love Linux Fedora for instance, but unless you are going to live forever to support your friend, consider what help is available in the community. Here is a graph of the popularity of Linux distributions… and Fedora is way down on the list. And linux is less than 3% of desktops to start, so multiply 0.03 times 0.002 and you get about 1 in 10,000 computers running Fedora… Now start expecting community support, based on those numbers. Good luck.
