Hello vaidi koli, welcome to Microsoft Q&A forum.
Have you tried the AI answer? Does it work?
Actually, there are two types of region settings in Windows 11:
Regional format: Mostly cosmetic, affects display formats like date/time format, currency symbol, keyboard layout. The AI answer covers this - you can change it in Settings > Time & language > Region.
Device setup/OOBE region: System-level setting that sets your Store region, determines which apps are available in Microsoft Store, and affects default content/services for your region.
If by "region" you mean this (the one you selected during laptop first setup), you'll need to change it this way:
Option A - Registry Edit:
• Press Win+R > type regedit > Enter
• Navigate to: HKEY_CURRENT_USER\Control Panel\International\Geo
• Delete the Nation key
• Restart PC
Option B - Clean Reinstall (most reliable):
Reset Windows (Settings > System > Recovery > Reset this PC), selecting India during initial setup.
