I see, it switches to Istanbul when turned on. Please open Services (press Win + R, type services.msc), find Windows Time and Geolocation Service, set both to Automatic, then start or restart them. Test again.
Set time zone automatically defaults to wrong time
Once time Zone is set, if i toggle the set time zone automatically, the time changes to another country

2026-04-05T09:10:55.71+00:00 Hello, are you connected to a VPN or using location services on your device?
Open Settings > Time & language > Date & time, turn off Set time zone automatically, then manually select your correct time zone from the list. Next go to Settings > Privacy & security > Location, turn on Location services, and click Set default under default location to choose your region. After that, restart your PC and avoid turning the automatic time zone back on unless your location is detected correctly, this ensures Windows uses your chosen region instead of detecting the wrong one.
