Those Microsoft employees developing new features for Windows wouldn't have anything to do if they didn't try to invent [often / mostly?] useless stuff. ;)
Some new things do have a purpose, but for Microsoft, Not you. Microsoft's spent tons of money on Bing, but even paying people to use it with rewards hasn't helped it gain ground against Google. So now they're loading features into their Edge browser, like shopping & rebates, and they gave you News & Interest in Win10, & Widgets in Win11 -- the hope is that you'll click something, which would open Edge & use Bing. Both can thankfully be turned off. TO turn off New & Interests right click the Task Bar, hover the cursor over News & Interests, then click on Turn off.

There are a couple of tiny free apps that can help tame some of the junk Microsoft stuffs into Windows. WinSlap for Win10, ThisIsWin11 for Win11.

The (Windows) Defender included in Windows has gotten pretty good -- it now gets top marks, competing with the very best AV suites at sites like av-test[.]org. One thing I'm concerned about is that since every copy of Windows includes Defender, it's got this HUGE target on its back -- cyber criminals may or may not always be working on ways to get past 3rd party AV software, but it's guaranteed they're constantly working to get past Defender. That and that it's still Microsoft, which despite having some truly brilliant people, regularly insists on shooting itself [and every user] in the foot.
We like BitDefender on our more powerful PCs -- it's got good to great protection, and stays out of the way... the only things you'll see are occasional notices that it blocked a dangerous web site, usually ad-related when you visit whatever site / page, and notices prompting you to turn on their VPN -- a data capped version of their VPN is included free. It's somewhat regularly on sale, with Total Protection going for $10 - $20/yr for 3 or 5 PCs, but it doesn't run well, is simply too much for i3 and slower CPUs. For those we run an older Mcafee package called LiveSafe, which includes their top-end suite & goes on sale every Black Friday [so far] for $10/yr for an unlimited number of devices. Like BitDefender it's top rated, but can be a little more intrusive unless you disable some of its features, e.g. vulnerability scans, which search for Windows & software updates.
You're not the only one on a 4 year clock gergn... there are billions of Windows devices that can't officially run Win11. I know I'm probably dreaming, but the Huge, HUGE problems because of Log4j, which could plague IT for years, **might** open some eyes in the big corporations, making them realize they need to support more open source projects. Maybe Wine [or another Windows emulator] might benefit? There will certainly be a Very large user base unless Microsoft either extends Win10 support or makes clear running Win11 on unsupported hardware is OK. Meanwhile do please continue posting about your experiences with Linux etc. as you look for your alternative.
