Friend, that which makes a mockery is not the joke, because it creates the joke, which itself likely is not.

That which is made a mockery is the joke because it was made such by that which makes the mockery.

A thing or person can make of it/themself, but this doesn’t apply to your case.

In your case, Windows was made a mockery by Linux, thus Windows is a joke.

Also if you knew this was going to be misread, you could’ve edited your comment at any time to accurately reflect your meaning.
