Windows 11 has recently garnered feedback from certain users, alleging that the system's start menu repeatedly showcases OneDrive advertisement banners, encouraging users to back up their files to the cloud. For users who have not subscribed to Microsoft 365 services, the system suggests purchasing additional cloud storage space for approximately $5. These banners feature a yellow warning icon and urge users to back up their computers using OneDrive, directly linking to the relevant operation interface upon clicking. The free version of OneDrive offers only 5GB of storage space, which is inadequate for the synchronization requirements of most users.
