Restore missing Time Zones in Windows XP and Windows Vista
Published: January 16, 2005Send your feedback
Symptom
When you open the Date and Time Properties and click the Time Zone tab, it shows only one Time Zone entry in the drop down (example: Time zone in India, GMT +05:30 Chennai, Calcutta, Mumbai, New Delhi). Also the map below shows only the India map instead of the entire World map. This does not let the user change his Time Zone.
Also in Windows Vista, when you click the Change time zone button, nothing may happen.
Resolution
This happens if the sub-keys of the following registry keys are missing:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Time Zones
For Windows Vista
Download timezones_vista.zip and save to Desktop. Unzip the archive. Right-click the file timezones.reg and choose Merge.
For Windows XP
Download timezones_xp.zip. Unzip timezones_xp.zip files and extract the timezones.reg file to Desktop. Right-click the file and choose Merge.
