The answer is yes: > Despite being Microsoft’s newest and ‘most secure’ operating system, Windows 10 was found to have the highest proportion of vulnerabilities of any OS (395), 46% more than Windows 8 and Windows 8.1 (265 each). https://www.avecto.com/news-and-events/news/94-of-critical-microsoft-vulnerabilities-mitigated-by-removing-admin-rights https://www.avecto.com/news-and-events/news/94-of-critical-m... And if you've used Windows 10, you'd already know that. Windows 10 has added a ton of new features/crap. The Q&A has suffered, too, and Windows 10 has been quite buggy so far, ruining some people's computers, etc. And since we were talking about Word, here's another tidbit from the same source: > Microsoft Office products were the subject of 79 vulnerabilities, up from 62 last year. This represents a 295% increase in Office vulnerabilities since 2014. The amount of bugs likely increases in general, too, because more code = more complexity = more bugs and bigger attack surface, especially if we're talking about "improving" or adding on top of an old codebase, as is the case with Windows and Office, as opposed to writing something from scratch (which may benefit from safer languages sometimes, newer safer architectures, etc).
