Computer Configuration\Administrative Templates\Microsoft Edge\Content settings User Configuration\Administrative Templates\Microsoft Edge\Content settings Description
Setting the policy to "BlockWindowManagement" (value 2) automatically denies the window management permission to sites by default. This setting limits the ability of sites to see information about the device's screens and use that information to open and place windows or request fullscreen on specific screens. Setting the policy to "AskWindowManagement" (value 3) by default prompts the user when the window management permission is requested. If users allow the permission, it extends the ability of sites to see information about the device's screens and use that information to open and place windows or request fullscreen on specific screens. Not configuring the policy means the "AskWindowManagement" policy applies, but users can change this setting. Policy options mapping: * BlockWindowManagement (2) = Denies the Window Management permission on all sites by default * AskWindowManagement (3) = Ask every time a site wants obtain the Window Management permission Use the preceding information when configuring this policy.

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.
