Software\Policies\Microsoft\Edge\AutoOpenFileTypes Description
This policy sets a list of file types that should be automatically opened on download. Note: The leading separator shouldn't be included when listing the file type, so list "txt" instead of ".txt". By default, these file types are automatically opened on all URLs. You can use the 'AutoOpenAllowedForURLs' (URLs where AutoOpenFileTypes can apply) policy to restrict the URLs on which these file types are automatically opened. Files with types that should be automatically opened are still subject to the enabled Microsoft Defender SmartScreen checks and won't be opened if they fail those checks. File types that a user has already specified to automatically be opened continue to do so when downloaded. The user continues to be able to specify other file types to be automatically opened. If you don't set this policy, only file types that a user has already specified to automatically be opened will do so when downloaded. This policy is available only on Windows instances that are joined to a Microsoft Active Directory domain, joined to Microsoft Azure Active Directory or instances that enrolled for device management.
