In the new Windows system environment, the initial sign-in is not the end of the desktop environment. The first time you sign in, the icons in the Start menu, the drive name display in Explorer, and the default page settings in your browser may not be in the state they should be.
After signing in for the first time, please sign out and sign in again to start using the system.
By the time you sign in the second time, your desktop environment will be ready.
