Windows 10: Time Zone Changing to India

Hello everyone,After the last update 2025-06 Windows 11 24H2 KB5063060, my system booted and automatically changed my timezone to India. My time is set to change according to my location and right now I'm located at São Paulo Brazil, every IP address verification site states that I'm at Brazil, but Windows insists on telling me I'm located in India.I've set my time zone manually but I'd like to report this as a bug or something. I've already checked all my network configuration, did a netstat verification, an antivirus complete scan, and unfortunately this is still happening. Sometimes it work

:)

 

There is no Indian time zone in the time zone list of windows 11

So i just updated windows 10 home to windows 11 home and i noticed that the time was wrong so i went adjust date and time and the time zone was set to seoul then i tried changing the time zone to India but there was no India in the list can anyone help me get the Indian time zone.

 

Unable to change the time zone in Windows 10

I'm running Windows 10 Pro. My time zone is Jerusalem, but I need to change it to Eastern to test a program I'm working on.

The time zone won't change. I have tried:

• From the clock/calendar, when I change it - it changes back.
  
• From Control Panel - Date and Time, "Change time zone..." - when I click save I get the message "Error occurred - your changes could not be saved."
  
• As the Built-in Administrator from the command line using tzutil - I get the message "Insufficient privileges to set the current time zone."
  

The registry key TimeZoneInformation has Full Control for Administrators

Administrators are listed in the Local Security Setting "Change the Time Zone"

Any suggestions?

 

Time Zones do not change

Hi Andre,

Thanks for taking the time to help. I appreciate it.

I opened the account on my computer which has Administrator Privileges and ran regedit.

In the first string you suggested, it was already set to NTP.

In the second string, I changed the value to 3, as instructed.

Regrettably, after the restart - the trouble is still present. The Time Zone is still stuck on the time zone of the place I started my trip from.

I opened Settings>Time and confirmed that the toggle is set to Automatically Detect/Change the Time Zone, but it clearly isn't working. Additionally, the place where it displays the Time Zone (which if you click on usually drops down a list where you can
select a new TZ) is grayed out and not longer drops down a list if you click upon it.

Also grayed out is the toggle allowing you to choose to ignore Daylight Savings.

Hmmm. Puzzling.
