December 2014 cumulative time zone update for Windows operating systems

Support for Windows Server 2003 ended on July 14, 2015

Microsoft ended support for Windows Server 2003 on July 14, 2015. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

Summary
This update supersedes and replaces the update that is described in Microsoft Knowledge Base article 2981580, which was released in August 2014. All additional time zone changes that were released as hotfixes after update 2981580 was released are incorporated in this update.

If you have already deployed update 2981580, read the descriptions of the specific time zone changes that are addressed in this article to determine whether you must deploy this update immediately. If no systems are affected directly, you can schedule deployment at the next available opportunity.

We recommend that you deploy the most current Windows cumulative time zone update to guarantee the consistency of the time zone database on all systems.

Important
  • Before you apply the update that is described in this article, be aware of potential issues that may affect Microsoft Outlook. For more information about these issues, click the following article number to go to the article in the Microsoft Knowledge Base:

    931667 How to address time zone changes by using the Time Zone Data Update Tool for Microsoft Office Outlook
  • Cumulative time zone updates contain only data that has changed for a specific region or that was added to maintain parity with other operating system versions. Therefore, if a time zone-related registry subkey is deleted, some original values may not be restored after you apply the cumulative zone update.

    Note We do not recommend that you delete any registry subkeys that are related to time zones. On a computer that has incomplete time zone subkeys, first restore the time zone subkeys from a known good backup. Then, apply the update.
More information
The update that is described in this article changes the time zone data to accommodate daylight saving time (DST) changes in several countries.

This is a cumulative update rollup that includes all previous Windows time zone changes. For more information about how DST changes may affect other Microsoft products, go to the following Microsoft website:

This message indicates that either you have already applied the correct update or Windows Updates or Microsoft Update has automatically installed this update. No additional action is required to update the Windows operating system.
