In previous versions to Windows, when you press print screen (prtsc) button from keyboard it saves the screenshot to windows clipboard and you need to paste it in an image editing tool to save it. If you want to take multiple screenshots then this might be the problem because you need to save the taken screenshot first and then take next one because Windows clipboard holds only one screenshot. In Windows 8 Microsoft added an new shortcut to capture screenshots and save it to a folder in Pictures automatically without using any software or utility.
Capture Screenshot in Windows 8.x and Save Automatically
To capture and save screenshot automatically as a file in Windows 8 you need to open the required window/screen that you want to capture and then press Windows+prtsc key from keyboard, you will notice a fade effect that show you captured it. Once you done this a screen shot is taken and saved in folder under Picture > Screenshots.
Open Windows Explorer, on the left side expand This PC and then click on Pictures. Here you will find a Screenshots folder, open it and all the screenshots that you taken will available here.
This Windows+PrtSc shortcut can only saves the whole screen and you can’t use the Alt key combination to capture and save on the Active screen. I think Microsoft should add that 🙂
