Microsoft has explained their policies with respect to these changes and their products. If you are running Windows XP SP2 or Windows Server 2003 then the update is available through Windows Update. It's worth running a manual Windows Update to make sure that you have installed it, even though Microsoft had planned to make the update "Critical" at some point in order for it to be installed under Automatic Updates.
If you are running Windows 2000 then you can get an update only if you have a contract that has Extended Hotfix Support, which is not a standard support feature. If you are running other operating systems, such as Windows XP SP1 or Windows NT, sorry, no update.
All Windows versions can also be updated manually by the user with some registry hacking or the use of the tzedit utility as defined in Knowledge Base Article ID 914387. Both processes look somewhat involved, but the tzedit process less so.
Here is Microsoft's "solution" for W2K and NT users - manually hack the registry or download Time Zone Editor and manually edit the time zones! Why not release a Windows Update that updates the time zones for W2K and NT?
