Stupid Desktop Question

[Sir Face]

I realize this is one of those "Duh!" questions in advance, but, I haven't been able to figure it out so here goes:

When I set a new desktop picture here on my SP2, the same desktop image appears on my big HP desktop, whether I want it to be there or not. How do I "un-sync" the two, to where I can have separate images on both machines?

Go to PC Settings>SkyDrive>Sync Settings and turn off Desktop Personalisation/Appearance
