OK, you asked for it. This is my Tier 9 nuke of Windows advice!
O&O have two freeware products, O&O Shutup, which neuters the MS telemetry, and O&O Appbuster, which helps you uninstall the bloatware that comes with Windows 10 (Paint 3d, upsell Solitaire, etc). Between those two, I find Windows becomes much more tolerable.
I also use Open Shell, which gives you back a Windows 7-ish start menu, and Winaero Tweaker, which lets you mess with some of the other silly defaults Microsoft chose.
Be careful, though. It's not always obvious what changes will do. For instance, I used to use a custom hosts file which blocked the URLS associated with Windows Telemetry, but they have now set Windows Defender to detect and revert that.
Details here: https://www.bleepingcomputer.com/news/microsoft/windows-10-hosts-file-blocking-telemetry-is-now-flagged-as-a-risk/
(If your router gives you a decent amount of control, you can set such a hostfile there, and Windows can just... deal with it!)
I also run TInywall, a more versatile interface to the built-in firewall (again, reading needed or you will be sad when things break). It lets you block outgoing connections, which the defaults don't. You wind up having to whitelist apps that you want to access yon Internet, but that means apps that sneakily try it are blocked.
I find it worth the hassle, but you may disagree.
Also, out of a surfeit of paranoia, I like to use the free version of Malwarebytes to run a when-I-feel-like-it scan on demand for malware.
(I don't trust Windows Defender. For one thing, they avoided the Leadership pool completely, always a bad sign on a Defender!)
Every time you update (or are forcibly updated), be sure to check your settings, because Windows will decide to change things.
Finally, for extra credit, do you know how many copies of Adobe Flash Player (a notoriously, ridiculously insecure vector of infection) you have installed on Windows 10?
Have a look in C:\Windows\System32\Macromed\ and C:\Windows\SysWOW64\Macromed\ and C:\Windows\WinSxS\ and count again!
(And that's if your browser doesn't have a copy!)
Anyway, thanks for letting me vent. Bleeping Computer (cited above) is a good site for more detailed advice, and the first place to go if you break something. Remember, my guarantee is, if you take my advice and something breaks, you get to keep all the pieces!
Please be safe out there, and good hunting!
