Hi if you right click the desktop screen and click view, and then untick Show Desktop Items, does it go away, let us know.

it doesent have that option.

It is in your pic two up from the bottom on the right, untick that box that says Show desktop Items. Ok Sorry Icons.

no it does not go away any other ideas

but thankyou

Strange does anything happen if you click it or double click it,?

When did this start, or was it always there.?

Have you put on a windows desktop pic or something?

Post a picture of your Desktop please.

Use Karen's Window Watcher

This will allow you to detect/determine if it is a process window. YES - there are many hidden windows on your desktop.

It may be a window or an artifact. Have you recently updated/modified any drivers, esp video?

no i can even put a desktop icon over the top
