Windows xp not updating dst
Let us see what is Daylight Saving Time, what this notification means and how to change Daylight Saving Time on a Windows system.
Those of you who do not know what is Daylight saving time DST, let me explain in brief.
If the time zone being updated is the time zone the system is on, it calls the API function Set Time Zone Information() to update the information that the kernel reads at startup in the registry.If this is the scenario you are seeing, you can run the following script after the hotfix is applied to automate the process of changing the time zone and ensure that the system runs with update DST2007 rules.followed by running the script above will reliably cause the system to follow the new DST2007 rules.After this, it updates a structure in the system that contains this information as well as send out a WM_SYSTEMSETTINGSCHANGE message to running applications The first problem described above seems to be happing during step #3.
Reasons for this failure may be related to security rights (this is still under investigation).
From time to time releases DST Cumulative Updates and Updates for Time Zone changes.
