You can see in above screenshot, Windows 10 is showing that available updates will be downloaded and installed automatically. If you open Windows Update settings page in Windows 10, you get following screen: Now Windows 10 will automatically download and install new updates without your knowledge and you’ll have no idea when and which updates Windows were installed. In Windows 10, you can’t change settings of automatically download and install Windows updates in its settings page. Microsoft didn’t want Windows 10 users to modify Windows Update settings, the company wanted to prevent them from disabling Automatic Updates in Windows 10. They did this because they wanted Windows 10 to automatically download and install all updates and hotfixes. Microsoft has disabled customization of Windows Update settings in Windows 10 by removing all options related to Windows Update downloading and installation. Same thing happened with Windows 10 operating system. In such situations, you won’t be able to change Windows Update download and installation related settings because all available options would be grayed out or completely removed. Imagine a situation when your system administrator or a 3rd party software or a malware disabled/restricted Windows Update settings page.
