It’s not such a joke for about 70 percent of the people who use a computer. All most people do is use the internet, write a document or two and check their email (most of the time using a web based service).
All of which can be done by any OS.
The only reason anyone would want Microsoft is if they specifically ran a program that required Windows … most will say that MS Word runs better on Windows which is true but most people I know write or view the most basic documents that any word processing software is more than adequate.
And even if MS word is required by your school or work … get them to pay for the OS and the word processing software.
Otherwise, the majority of the people I know with a computer only use it as a glorified tablet to access the internet and browse social media … all of which can be done with the most basic Linux distro that won’t hassle you with annoying popups asking you to do things you shouldn’t even be thinking about.
