Win10 from what I’ve seen is highly customizable. See earlier discussion about PowerShell for super geeks wanting under-the-hood control.Thanks for looking. I felt like I thoroughly exhausted trying before I pleaded for help. As someone who intentionally skipped a decade of Windows iterations, it seems like there's less customizing for users now and more control for Big Brother. This is one reason I put off coming into the 21st century for so long.
And if WinDefender doesn’t suit you, turn it off. It’s got a lot of customization in Settings including firewall customization.
I’m an Apple Mac & iOS user for personal devices. But Win10 is good. I think avoiding upgrading from Windows XP (or worse Win98) is ... well ... kinda crazy. Win7 was good and what I’ve seen so far Win10 is pretty great, far more secure, and keeps getting better with the semi-annual updates.
Nothing’s perfect. Computers are complex. Problems happen to the best of us. But, yeah, Win10 is good stuff.
