Okay, so this isn't the most serious issue that Windows 10 users have faced, but it's still a useful tip to keep in mind. When you have a lot of programs open, it can be a chore to minimize them all to get back to the desktop when you have to click the little 'line' icon top-right again, and again, and again.
In fact, there is a keyboard shortcut that will minimize all active windows at once. Simply press the Windows key+D to return to the desktop in a flash. Developing this habit will save you a lot of time in the long run.
