Can't download MUI

Hello,
I want to download and install Polish MUI from Windows Update but I can't find it (MUI). Any ideas? Is there any other way to get MUI from Microsoft?

If I chosen wrong forum, please move this thread :)

Have you checked the Optional Updates section inside the windows update?

Windows 7 language packs are available for computers that are running Windows 7 Ultimate

Here is the info from Microsoft on it.

Yes, I already checked it.
Is it possible that MUI isn't compatible with build 7201?
