Why can't the weather of win8. 1 be used?

1. Create a new user, keep the default settings of UAC, and ensure the normal network. 2. If the system has been cleaned by third-party software, do not clean up or change the% appdata% \..local \ packages directory, otherwise you will find that the Metro application that comes with the system cannot be opened after being updated, and can only be solved by creating new users or reinstalling it.

3. Try to switch between "online account" and "local account", and press Win+I→ Change computer settings → User.
