Post an updated to an app which was supporting Windows 10/11 but now supports only Windows 11

To upload a new release of your app that supports only Windows 11 while keeping the older version available for Windows 10, you can follow these steps:

1. Create a New Submission: In the Microsoft Partner Center, create a new submission for your app.
2. Package Versioning: When uploading the new package, ensure that you set the Device family availability to target only Windows 11. This will allow the new version to be available exclusively for Windows 11 users.
3. Maintain the Older Version: Ensure that the existing version of your app, which supports both Windows 10 and Windows 11, remains published in the store. This way, users on Windows 10 can still access the older version while new users on Windows 11 will receive the updated version.
4. Gradual Rollout (Optional): If you want to monitor feedback on the new version before a full rollout, consider using the gradual rollout feature, which allows you to release the update to a percentage of users initially.

By following these steps, you can effectively manage the versions of your app for different Windows operating systems.
