Windows 10 Technical Preview has been available for quite some time now. For those of you who are eagerly testing away as part of Microsoft's Insider Program, you have likely noticed the new "windowed" app mode. This mode allows you to minimize, maximize, and even resize modern apps as if they were regular desktop apps. This is a familiar functionality that Windows 8 (and Windows 8.1) lacked.
These apps are in a familiar format that you are used to. The apps can be resized, they can be moved around, and they have title bars at the top with common functions, making it a dream-come-true for non-touch users. However, on the title bar is a setting that allows you to return your modern app into full-screen mode, which is ideal for certain types of apps. In my case, I prefer to have Tweetium or my Calendar app in full-screen mode.
Simply click the app's option button (see screenshots below) and you will be presented with a list of actions. You can search, share, print, or change settings. This is where you can enter or exit full screen mode. The functionality you see in this menu varies by app.
