I insist all the problems with Win10 stem from users not learning anything about the devices they use. It reminds me of a blind guy complaining about the Chevy Impala when he crashes a car. I use Win10 from a clean install, updated regularly. I run a good quality MS compliant workstation. Use Chrome with Ad-blocker. I don't run widgets or other do-dads, never install software from an unknown source, use no anti-virus other than Defender, and have turned off all the Win10 telemetry. I never use social media (Facebook, Twitter, etc) on mission critical computers. I also use a physical firewall in addition to the Windows Firewall. I have zero problems with Win10 and it's updates (which I do manually). Zero! In fact, I have had many more problems with previous versions of Windows, especially XP and Win7 (albeit less). If you have problems with updates it most likely due to your ISP (speed and reliability of connection) and not with Windows Updater. The number of devices in use on your LAN can also be a factor during updates. WiFi can be very unreliable depending on the quality of the router and the distance of the computer from it. I use shielded Ethernet hard-wire exclusively. Again, these factors have nothing to do with Windows Updater. If you have no understanding of how computers function or refuse to learn what is required to know, you're a blind guy driving a Chevy. Don't blame GM or the car model. Blame yourself.
