Actually it did end up quite simple. The link above led me Here
where I found a free program called vistalizator. I downloaded the language pack and this freebie installed it, so I now have an English OS. So thanks for the original link.
Strangely some things still come up in Spanish but I can live with that. However.....
This laptop has microsoft office 2010 starter installed and that is still totally in Spanish. Any ideas how that can be changed anyone?
