As to installing the security updates, you've spent enough years on the forums to know what happens when people don't keep their device updated. It is one thing to delay the version upgrade but when there are critical security updates, I personally don't choose to wait.
I don't either. In fact, it is common for me on this, my primary computer, to check for and install any updates on Tuesdays, the day they traditionally are released.
I started doing this right away after migrating to Windows 10 primarily because I wanted to practice what I preached to my family and my clients. That is, "
keep your operating systems current. That is a primary defense against the bad guys". I also wanted to install the updates first just in case there were problems - so I would be familiar with them (and how to fix them) should my clients call.
But as it was, problems didn't happen. Updates installed just fine. I didn't get any calls. Yes, over the years, there have been a couple (less than a handful) of hiccups. But worse case was fixed by a simple reboot.
Now I have encountered other computers that had problems after updates but what I discovered was those computers had many default settings that were changed by the user. They used 3rd party security programs, driver update utilities, and/or they dinked with virtual memory (page file) settings, and more. In many cases, those computers were older hardware - upgraded from W7. Hardware that often lacked solid W10 driver support from the HW maker.
Now I cannot and will not say those programs caused the problems, or that you will never have problems if you leave the defaults as Microsoft sets them. But it sure "seems", at least from here, that less problems occur if you just leave Windows alone. Contrary to what many want us to believe, the developers at Microsoft really are some pretty sharp people who know what they are doing. Not sure I can say that about the marketing folks, or some of the executive decisions made in Redmond, but the developers have done and are doing a good job.
