Win10 from what I’ve seen is highly customizable. See earlier discussion about PowerShell for super geeks wanting under-the-hood control. 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.
