Many people wont remember and maybe never knew about the Aero features in Windows 7. They didn’t add much functionality but they were essentially the beginning of the redesign we saw in Win 8 and has reached a polished state in Win 10.
You probably know of Alt+Tab as a shortcut to switch between active programs. This still works great in Windows 10. The new addition which adds a lot of value is Windows Key + Tab. This shortcut pulls up a new screen highlighting open windows on the screen they are active. If you’re using multiple monitors this could be a life saver! Use your monitors to organize your windows even when switching between tasks. See a Screen Shot Below!
