Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
This policy controls the default value for the "share additional operating system region" setting in Microsoft Edge. The "share additional operating system region" Microsoft Edge setting controls whether the OS Regional format setting is shared with the web through the default JavaScript locale. If shared, websites can query the OS Regional format using JavaScript code, for example; "Intl.DateTimeFormat().resolvedOptions().locale". The default value for the setting is "Limited". If you set this policy to "Limited", the OS Regional format is shared only if its language part matches the Microsoft Edge display language. If you set this policy to "Always", the OS Regional format is always shared. This value could cause unexpected website behavior if the OS Regional format language is different from the Microsoft Edge display language. For example, if a website uses the JavaScript default locale to format dates, the names of the days and months are displayed in one language while the surrounding text is displayed in another language. If you set this policy to "Never", the OS Regional format is never shared. Example 1: In this example the OS Regional format is set to "en-GB", and the browser display language is set to "en-US". Then the OS Regional format is shared if the policy is set to "Limited", or "Always". Example 2: In this example the OS Regional format is set to "es-MX", and the browser display language is set to "en-US". Then the OS Regional format is shared if the policy is set to "Always"; however, the OS Regional format isn't shared if the policy is set to "Limited". For more information about this setting, see https://go.microsoft.com/fwlink/?linkid=2222282. Policy options mapping: * Limited (0) = Limited * Always (1) = Always share the OS Regional format * Never (2) = Never share the OS Regional format Use the preceding information when configuring this policy.
Registry

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
