We want to change the language to English - Sony VAIO VGN-FJ270/B Notebook

Only Windows 7 Ultimate, Mac OSX and Linux operating systems (OS) can change the language of the menus and icons.

Most probably you have Windows 7 Home Edition
If you just got this PC you can reinstall a new operating system in English that you buy. Installing this will completely erase and replace the present system, files and programs.

Another way is to do a dual boot - a computer loaded with two separate operating systems on two partitions (C: and D: which you create) on the same hard disc. This will give you the choice of using the original OS or another one in English for example Windows XP or a free Linux Ubuntu OS. Google Dual Boot for instructions for your model of Notebook. This will involve some study and experimentation and you may lose the OS you have now, so back up your data. Here is an example of dual boot instructions:
