Hey Alaklabi,
I understand that you want to remove the USA events from your lock screen on your Surface device. To change the region or disable this feature, please follow these steps:
- Go to Settings > Time & Language > Region.
- Under Country or region, select the one that matches your location and preferences.
- Under Regional format, select the one that matches your language and date format.
- Go back to Settings > Personalization > Lock screen.
- Under Choose an app to show detailed status, select None.
This should remove the USA events from your lock screen. Please let me know if this does not resolve the issue!
