Use your start menu to open language settings :

Start - Programs - Microsoft Office - Tools - Language Settings

If you do NOT have a tab for user interface language, or if you click the
tab and can't find an option for English, then you'll have to install the
English language pack (it costs about 30 U.S. dollars), then come back to
this tool to change your interface language to English.

I just bought this laptop from my sister. For some reason only word, excel,
and powerpoint programs are in Spanish. Do I need to purchase a language
pack for this or is there a setting to change it all back to English?
