Hi everyone, thanks for the interest you guys are showing.
@skwire: i only need minimize all functionality for the show desktop.
let me explain again, i m on windows 8.1 64 bit, there is a "Show Desktop" small transparent button in the system tray on full right side, what it does is from a layman pov is, it work like pressing "Win key + D", but i want it to do the functionality of "Win key + M".
"Win Key + M" only minimizes all the open windows. which shows my rainmeter customization and my docks on the desktop. but "Win key+ D" minimizes all the open windows and place desktop windows on the top of the stack, which hides my docks and some of my rainmeter customization.
if still confusing let me know and i will upload screenshot of my desktop tomorrow.
