This is true to an extent. As mentioned earlier though, it is possible that through some low level access to various components, ie: sound drivers, it is entirely possible for errors to arise that had not previously been exposed. My golf sim example above is a classic case. Even though the system had been running fine prior to its installation, the golf sim crashed continuously until I found the generic driver conflict.
Anytime you encounter crashes, your first steps should always be to ensure no hardware issues exist. A hidden issue like my example can waste valuable time emailing back and forth with support just to have them scratching their heads and asking you to do a reinstall of sometimes dozens of libraries, attached accounts, Windows components, etc., leading to the inevitable full re and re of your system. All of which could have been solved with a simple setup change.
I know we have stability issues, but far too many people are NOT having issues to discount our own systems out of hand.
