I bought a new computer in a Spanish speaking country and it seems to have been pre configured in Spanish. However during the initial set up when given a language option I chose English. Now only a few of the punctuation keys produce the image on the key. The salesman told me changing to English changed the keyboard so for example to produce @ I have to press the arrow for upper case and the number 2. Except for comma and period no other puntuation maks work as expected. How can I fix this and if the answer is return to the prefigured settins how do I do that. Note absence of question mark following that last sentence or parentheseis for this one.
