How do I make Time Zone and Daylight savings time information set via Date/Time applet persistent As far as I can tell, this information is stored in a volatile registry key and gets lost after system reset.
You should be able to persist the settings by running RegFlushKey(). This saves the full registry to a partition in the flash memory. Details about this driver are posted in topic 843.
Note that our current boot code erases the saved/persistent registry when the CE image is reloaded.
