Are you trying to delete the windows.old folder left over from an install, or are you trying to delete Windows?
If you are trying to delete Windows, which drive is it on in the screenshot? What OS is it?
If you are trying to delete windows.old, I am sorry I misunderstood your post which says you are trying to delete Windows from the HD:
