Microsoft has released a promotional video demonstrating the transition from Windows 10 to Windows 11 using its Backup app, which simplifies data and settings transfer from an existing PC to a new one. The video emphasizes the need for OneDrive subscriptions, as the free account offers only 5GB of storage, which may not be sufficient for many users. Users can avoid subscription fees by selectively transferring larger files, such as photos and videos, to an external drive. A future feature in the Windows Backup app will allow direct PC-to-PC migration via a local network, but it is not yet operational and requires a Microsoft account. The promotional video does not mention this feature.
