Border around window screenshot

After the Windows 10 Anniversary upgrade, the Alt+PrtScn combo captures a border of some size around a window, as in the screenshot below. Is it possible to have only the active window captured?

Can you take an Alt+PrintScreen shot of a File Explorer window, for example: "C:"

It doesn't on my AU. I'd check you still have the correct video drivers installed.

Use this: Screenpresso: The Ultimate Screen Capture Tool for Windows

Capture just the area you want with no cropping required and no border.

Or the built-in Snipping tool that does much the same. The OP's query though was regarding the use of Alt-PrtSc which is not working as it should.

Yes, the same thing happens.

I'll check with the other suggested options, thanks! I've set a 125% magnification though, not sure if it might be causing the problem.

You're welcome.

And yes, try to reset your magnification down to 100% and try it out. If that doesn't work...

Try to uninstall your video drivers, and have Windows automatically re-install them with their most up to date versions.

Just giving the OP a betteroption.

Alt+Print Screen is so much easier and faster than using a 3rd party software. I'm not saying anything bad against the software you suggested, I just think that it's more convenient to keep things very simple.

It doesn't seem to be related to the magnification, and Windows detects that I'm already using the latest graphics drivers.

I'm actually already using a lightweight screenshot program that generates a png file when I press that combo. Just that it doesn't automatically trim the extra space around the window.
