Ok fairly unimportant query here

To minimise all my open windows and get to the desktop, i have always used "WINDOWS + D", however I read an article which stated "WINDOWS + M" was the way to do it, and yes it works perfectly well.

But my question is, is there any actual difference, apart from WINDOWS + D having the slight advantage of if you press it again it restore everything to where it was, whereas WINDOWS + M you have to do a WINDOWS +SHIFT + M to get back to where you were

Just curious as i had never heard of or used WINDOWS + M before today

Cheers
