Dear senior citizen George,
You said that you know how to go to the control panel, when you go to the control panel, in the top bar, click on the 3rd button which should be "View" the drop menu should appear, click on the 6th item from the list which should be the equivalent to icon, now the main window should show icons. Double click on the globe map., from there you should be able to open the drop down menu to change the language.
P.S. I assumed that the machine has XP
