I just downloaded the Kindle app for my Windows 10 PC. When I open a book, the app takes up the entire screen. I can't see any of my other apps, and I can't figure out how to close Kindle or switch to another app. If I hit ESC, it does nothing. The only way I can get out of the book is to hit the Windows key on my keyboard, but this doesn't seem like a useful solution.
This drove me nuts, too. Alt-tab will allow you to move away from the the Kindle screen, but it doesn't close it. If Kindle offers a direct keystroke to close the program, they're keeping it a secret. But here's how you can force close it: move your cursor over the "K" (for Kindle) in your Windows Task Bar. Right click and select "Close window". Adios Kindle.
On my Win10 machine I just downloaded the kindle version amazon made for windows 7 because of all the issues I had with the version from the store. You could try using that in the future. https://www.amazon.com/gp/kindle/pc/download
The Kindle app must think it's on a tablet, or it's a "tablet only" app for Win 10, so it will have no visible title bar or close/minimize/maximize buttons. There are 2 ways.
- Using your finger (if a touchscreen) or mouse, "grab" the top of the Kindle app window where the title bar would normally be, and drag the window down. The app will disappear and this will close the app.
- or hit the Escape key. This should also exit the app.
In both cases you will likely return to your (what I call) "tablet desktop", which is different from the normal Windows desktop that has been in use for 20+ years. The "tablet desktop" has link to many apps, but in the bottom left (on my PC anyway) it has a link to a normal desktop you are used to.
