Microsoft is migrating the functionality to rename a user account from the Control Panel to the Settings app in Windows 11's latest preview build (26300.7877). This feature is currently non-functional and users will need to wait for future updates to access it. The migration reflects Microsoft's effort to modernize the user interface, although the transition from the Control Panel to the Settings app is progressing slowly. Microsoft is prioritizing addressing fundamental issues within Windows 11, making significant acceleration in the migration effort unlikely in the near future. The Control Panel is expected to remain part of the operating system for the foreseeable future.
