I bought my laptop in Spain and am familiar with the Spanish OS which I haven't been able to change to English (Windows 7 home premium). Will I still be able to receive my upgrade here in the UK? What will happen? I don't mind if I get Windows 10 in Spanish, I just want to be sure that there won't be any technical problems that will affect my machine badly. Most of the programs I´ve installed such as MS office, Adobe etc run in English - will this cause any problems? Any advice gratefully received.
