Microsoft's Windows 11 system has undergone new changes, and its recommendation system has been upgraded again, extending the advertising tentacles to the notification bar. The notification system is gradually becoming a new channel for Microsoft to promote its own products and services.

In the gaming field, Microsoft not only recommends users to buy the vault edition of "Call of Duty: Black Ops 6", but also enters the security software market and promotes its own Defender application.

These notifications are marked as "recommended", and users can easily mistake them for system prompts. Unless users actively close them, they will appear repeatedly. Users can easily block these ads and restore the peace of the notification bar by turning off switches such as "Get tips and suggestions" in the "Notifications" option in the system settings.
