I have a laptop running Windows 7 Starter Edition. What is the procedure for changing the language setting from Spanish to English?
Changing the display language of a Windows installation is only supported in Windows 7 Ultimate and Enterprise. On other editions (possibly not Starter, as it has strange restrictions, but certainly Home and Professional builds) you can install a Language Interface Pack, but this only translates a small portion of the most commonly used interface elements. Please see this link for downloads and further details.
