On a computer that is running Windows Vista, you apply updates to a Multilingual User Interface (MUI) Language Pack, to MUI files, and to MUI cache in the memory. However, when you restart the computer, the updates that you applied to the MUI Language Pack are lost.

For example, after you apply the update in Microsoft Knowledge Base (KB) article 930585 to the MUI Language Pack on a computer that is running the Romanian-language version of Windows Vista, the problem that is described in KB article 930585 is resolved by the update. However, after you restart the computer, this problem occurs again.

Note: After you restart the computer, the MUI files that are stored on the disk remain updated.
