Problem with Windows 10 start screen taking over the desktop

I am having a problem on Windows 10 where the desktop has been taken over by the start menu. I am no longer able to resize windows as one would on a desktop, but rather they are treated as apps. I will try to post some pictures of the problem. It is almost like Windows 10 has forgotten that it is not Windows 8 and has in addition deleted the desktop. I will try to post some pictures of what the problem looks like (the image in the background was my desktop background, now the remnant of the old desktop). I have tried changing the option in the settings->personalization->start->use full start screen, but to no avail. I have turned my computer on and off a number of times. The funny thing is that my other account on the same computer does not have the same problem, it still has the desktop fully functional. Any help would be greatly appreciated.

I found the answer by chance, I had to go to settings->system-> tablet mode
