Answer 1

Enumerate all desktop window with EnumWindows . Collect every visible window handle.

Call ShowWindow with appropriate arguments to make the collected windows to be visible/invisible.

Take note that all created windows after this operation will be visible. To hide desktop icons you shall spy the window structure (with a tool like Spy++), get specific window handle by its class name and then call ShowWindow on the obtained widnow handle.

Of course, EnumWindows and ShowWindow must be P/Invoked. See www.pinvoke.net for getting the correct declaration.
