Dell notebook, when I bought it, there was a time and weather forecast in the upper right corner of the screen, but it was gone later. How can I find it?

You click Start-All Programs-Dell? Stage weather? It's on the desktop? Have you tried? If you never make a system? This is Dell's own? Mine is a Dell notebook, too? Did you accidentally turn it off? You had a hard time finding it? Almost called customer service? Hehe? I hope you can find it, too
