Allow users to open files using the ClickOnce protocol
Microsoft Edge
Policy overview
Key metadata and intent for this policy.
Supported OS tags: Windows7
Allow users to open files using the ClickOnce protocol. The ClickOnce protocol allows websites to request that the browser open files from a specific URL using the ClickOnce file handler on the user's computer or device. If you enable this policy, users can open files using the ClickOnce protocol. This policy overrides the user's ClickOnce setting in the edge://flags/ page. If you disable this policy, users can't open files using the ClickOnce protocol. Instead, the file is saved to the file system using the browser. This policy overrides the user's ClickOnce setting in the edge://flags/ page. If you don't configure this policy, users with Microsoft Edge versions before Microsoft Edge 87 can't open files using the ClickOnce protocol by default. However, they can enable the use of the ClickOnce protocol with the edge://flags/ page. Users with Microsoft Edge versions 87 and later can open files using the ClickOnce protocol by default but can disable the ClickOnce protocol with edge://flags/ page. Disabling ClickOnce can prevent ClickOnce applications (.application files) from launching properly. For more information about ClickOnce, see https://go.microsoft.com/fwlink/?linkid=2103872 and https://go.microsoft.com/fwlink/?linkid=2099880.
