This tutorial will show you how to enable or disable sharing additional operating system (OS) regional format with sites in Microsoft Edge for your account or all users in Windows 10 and Windows 11.
By default, Microsoft Edge provides operating system (OS) regional preference information to help website authors create regional experiences on their website, when viewing your site using Microsoft Edge. This feature allows website authors to deliver value to users who specifically change their regional preferences in the OS to reflect their personal preferences.
Users want to see dates, times, numbers, and other formatting printed according to their preferences. For example, the US geographic region translates 7/2/2022 into July 2nd, 2022. Another geographic region could translate that same date into February 7, 2022 because they read the month and day inversely.
Users can change the Share additional operating system region setting in Microsoft Edge to select the level of information below their browser will share about their regions:
- Limited (default) = The OS regional format is shared only if its language part matches Microsoft Edge display language.
- Always (not recommended) = The OS regional format is always shared. This may cause unexpected website behavior if the OS regional format and language are different from Microsoft Edge display language.
- Never =The OS regional format is not shared. Websites may determine a region based on the Microsoft Edge display language.
