Important Post-Use Information

1. When you have updated the PC’s time zone information, this updater is no longer needed.

2. In order to make this utility have as little impact as possible on your PC, un-install information is not placed on the system. This means you will need to manually delete the files if you wish to get rid of the updater.

3. If you accepted the default installation prompts, the updater files are located in the folder:
   
   x:\dcsTools\\TZ_Updater
   (where “x” is your Windows boot drive letter)

4. You may wish to save the two time zone information backup files if you chose to back up the original time zone information on the PC. The files are named:
   
   Backup_TimeZone_Info.reg
   Backup_Selected_TZ_Info.reg
   
   All other files can be removed.
