 I'm using Ultimate so don't see/have that "right click the background and turned on the "show desktop icons"" but here how to add from my version...

Right click > Personalize > Change desktop icons

1 .   Right click on icon of "Computer", open "Properties".

2 .   Click on "advance system settiings".

3 .   Click on "Advance" tab and then settings.

4 .   Click on tab "Visual Effects", then on radio button "Adjust for best apperiance" and OK.

Operating system will give maximum visual display.

to change settings,go to Start>>Control Panel,there u can set everything.language,display,color,.....
