Question: On iOS devices you can take a screenshot by pressing the home & sleep buttons at the same time. Is there a similar way to take a screenshot with Windows Phone?

Answer: 
There are a few ways to take screenshots:

1. If you're just a developer and just want to take screenshots for marketing your app, you can use the [emulator's screenshot tool](http://msdn.microsoft.com/en-us/library/gg442300%28v=VS.92%29.aspx).
2. If you have a developer-unlocked phone ([$99 a year from Microsoft](http://create.msdn.com/), or via unofficial tools) you can use [third-party apps like the one described here](http://www.winsupersite.com/article/windowsphone75/windows-phone-75-screenshots-141063).
Windows Phone 8
---------------

Press and hold Start button and Power icon at the same time to take a picture of your screen.

Windows Phone 8.1
-----------------

Press the Power icon and Volume Up buttons at the same time to take a picture of your screen.

Windows Phone 7, 7.5

It do not provide a way to take screenshots without unlocking the phone with developer tools.

*The screenshot will then be stored into a "Screenshots" album in the photos.*
