Desktop Icons

Shortly after subscribing to RegTool my desktop went wacko. The icon were everywhere that I didn’t put them and taskbar was jammed with my desktop (duplicates). Tried to put them where they were, but that lasted for only a short time. RegTool said to uninstall their program and re-install. Did that, worked for two weeks then same problem. Taskbar was locked from the beginning.
Any ideas for when this happens again??
