How to stop my laptop from opening everything in desktop?

I have a ideapad laptop and it has the new windows design. Everytime i try to open internet explore or chrome or firefox or flat out anything it opens the desktop. So ofcourse that changes how the layout is on the thing i open. Is it just the update or is it something wrong with my settings or am i even explanningg this right? Help

Added (1). its a lenovo ideapad

Would you provide us a screenshot, your sentence is quite unclear on that topic, plus we'd need the specs, OS etc…

But yeah, what would really help is a screenshot.

Hope this helped!
