Microsoft says Windows 10 will be “always up-to-date,” and they mean it. There’s no way to turn Windows Update off. To ensure everyone is secure and up-to-date on a stable platform, Microsoft won’t allow Windows 10 Home systems to delay Windows updates. Updates will automatically download, and they’ll be installed when you next reboot, or you can schedule a reboot. You’re not allowed to disable Windows Update entirely, and you’re also not allowed to put updates off if you don’t want to install them.
But they’re forcing more than security updates, and Microsoft has a troubling track record with broken Windows updates recently.
