I've been using Windows since 3.0. That version tended to crash for no obvious
reason. I've not had that problem with any later version.

Around 2004, "something" went wrong with my Windows 2000 installation. It
would boot, but its behavior was screwy. (This might have been due to a
malware attack, but I don't know for sure.) I was obliged to reinstall it, and
had no problems for the next eight years.

When people say that Windows is crash-prone, and/or often requires
reinstallation, I have to wonder what's going on. I've worked many jobs at
Microsoft, and have never seen this. I can only assume it's due to some sort
of user error, or badly written drivers.
