The "easy" solution here would be to create a new account named KCav, and transfer the content of the old "Owner" profile in the new KCav userprofile.
When I went to Control Panel/Users and created a User account named KCav, then rebooted in the c:users account KCav did not appear, only Owner. This occured on the two desktops and on the notebook. I was able to manually change the desktops but not the notebook.
