W7 ran its course from 2009 to 2020.
MS has notified that there will be no more support for W7, meaning its kernel will become vulnerable to attack:
"Security updates are essential to staying safe online, and Windows 10 is getting them while Windows 7 isn’t. Many flaws found in Windows 10 will also apply to Windows 7. Attackers will hear about them and can start attacking those vulnerable Windows 7 systems. As more time goes by, more unpatched, known flaws will exist in Windows 7 for exploiting. Hardware manufacturers are also supporting Windows 10 instead of Windows 7. This will only get truer after the end-of-support date. Even software companies will one day stop releasing new versions of their web browsers and other software for Windows 7." - How to Geek
Needless to say, drivers compatible to W7 will also not be updated by the various hardware and software companies.
Many aren't updating because their machines might be old. This is another error. W10 will run faster than W7 if the W10 requirements are met, and which aren't so different than the demands of W7.
True, the huge updates are a minus, but, they go hand in hand with security updates as well. Also, the updates have been getting smaller, perhaps because they involve enabling features present in prior downloads which sit quietly on your system until enough testing (supposedly) allows MS to "unmask" them.
The security, or lack thereof in W7, is well explained here: https://www.neowin.net/news/gchq-its-time-to-ditch-windows-7-if-you-want-to-stay-safe-online. GCHQ (Government Communications Headquarters), is an intelligence and security organisation responsible for providing signals intelligence and information assurance to the government and armed forces of the United Kingdom.
There's still a way to update to W10 for free: https://www.howtogeek.com/266072/you-can-still-get-windows-10-for-free-with-a-windows-7-8-or-8.1-key/
All in all, W7 is now an OS with a major liability, and you should migrate.
gHacks has a good take on W7's end of life: https://www.ghacks.net/2020/01/14/windows-7-support-ends-today-here-are-your-options/?_m=3n%2e0038%2e2414%2ehj0ao01hy5%2e2iur
