How do websites know I'm using windows xp pro spanish version?

I'm using windows xp pro spanish version.

How do websites know I'm using windows in spanish, so they automatically change their default language to spanish?

Some software when launching their installers they suggest spanish to choose from available languages.

When signing up to some web services spanish appears at the first option......

Do websites read windows regional and language settings in order to determine what language the operating system is using?

Do they read cookies? Do they use scripts or read the IP?

How do they know it all?How do websites know I%26039;m using windows xp pro spanish version?

For online applications, JavaScript properties (information about different stuff) hold information like this. I am assuming that other programs use similar system data. This is not a hack, and this data is read only (the programs can see this information to make your computer easier to use but can't change it). Cookies are pieces of data from different sites stored on your machine. This data exists in your browser (internet application) and system (overall computer information).



If you want to see this JavaScript code at work, try copying the following JavaScript/HTML code into a blank text document (make sure its .txt), saving it, and opening it in your favorite web browser (like internet explorer):



%26lt;script type=%26quot;text/javascript%26quot;%26gt;%26lt;!--

document.write(navigator.language+%26quot;%26lt;br?br>
document.write(navigator.systemLanguag?br>
document.write(navigator.userLanguage)

//--%26gt;%26lt;/script%26gt;%26lt;noscript%26gt;You forgot to turn JavaScript on! Check your browser's preferences or, if you see a security warning in IE, allow this.%26lt;/noscript%26gt;



PS: If you see %26quot;undefined%26quot;, ignore this. It's a weird problem I'm having (which is, in fact, ruining one of my programs :( ). Hope this works!
