The Search tool in the Microsoft Language Portal lets you access the Microsoft terminology database, with thousands of English terms, their definitions and their translations in more than 90 languages, and millions of software strings from localized Microsoft products (also known as UI strings, i.e. the text that appears in the User Interface of a product).
The localized Help (the so-called UA or User Assistance, available online for most products) is not part of the search options, but there is an easy way to look up how the topics were translated. Once you have identified the source text you are interested in, you can find the relevant translations by editing the page address:
