Use Linux - or I shoot
There’s something remarkable going on in the (operating system) software world. This has, actually, been going on for quite a few years. A lot of users tired of proprietary (’closed’) software and the licenses that go with it, and of course the flaws that many people perceive are in Microsoft Windows, now turn to something called Linux. Many of them get so enthusiastic that they start to actively convert Windows users to Linux.
It would be dishonest of me to claim that I haven’t tried this occasionally; the thing is that Linux and free software is actually often very good. But I did learn: don’t disturb the happy Windows user. They may use all kinds of illegally installed anti-virus software, they may have an unknown number of unnecessary services (or spyware programs) running on their pc’s; they may have all kinds of hidden frustrations, as long as they don’t complain, don’t try to linuxify them if they’re not really open to it.
Installing the Mozilla Firefox browser on Windows would be a good idea, though.
