To All,
Quick Suggestion from me to all.
apply to only : The One who uses "print screen" keyboard key.
suggestion : using this key only to take screenshot of current screen captures entire screen. to avoid getting unneeded(not required like start menu and background apps while your main app is not maximized) part use "alt(left or right any one)" to tell computer to take only active window and avoid capturing other parts.
special mention : "print screen" key stores screenshot in windows clipboard so avoid using any text data as cut paste or copy paste as it makes your screenshot deleted from windows clipboard.
supported os : works on any Windows NT(2000, XP, Vista, 7, 8, 8.1 & 10). for mac & linux see os guides for respective keywords.
