can i hide my desktop?

Question

i mean any software that allow me two seprate desktops so i can switch fast from one to another......

Answer 1

Yes, there is.
It's called a virtual desktop.
Stardock has a program that does this, I don't know if they have a standalone version or not, mine came with the Object Desktop Suite of programs.

There are surely other programs, perhaps some free ones, that do this as well. Go to some download sites, some are linked below, and search for virtual desktop.
