Windows 7 language packs are available for computers that are running Windows 7 Ultimate or Windows 7 Enterprise. The Windows 7 language packs can be installed only from the Optional Updates section in Windows Update. However, these language packs are not available on the Microsoft Windows Server Update Services (WSUS) server or through the Microsoft Download Center.
To download and install a Windows 7 language pack, follow these steps:
Start Microsoft Update. To do this, click Start, type Microsoft Update in the Start Search box, and then click Microsoft Update in the Programs list.
Click the optional update links for the language packs.
Under the Windows 7 Language Packs category, select the desired language pack.
Note If you install many additional language packs, the disk space and system performance are affected. In particular, disk space and system performance are affected during servicing operations, such as Service Pack installations. Therefore, we recommend that you only add a language pack to your computer if you will use the language pack.
Click OK, and then click Install updates to start the download and installation process.
