Windows 10 gained a bad reputation when it came to updates—the internet is full of frustrated anecdotes about Windows rebooting to install an update at exactly the wrong time, like right when you’re about to start a presentation, or when you’re working on a tight deadline. This is one of the things that Microsoft improved upon in Windows 11.
The system is more transparent now about installing updates, giving you notifications and warnings before doing so. If you tell it to delay an update, it actually will. Even so, once that delayed timeframe is over, it will force you to install the update.
