Allow users to open files using the ClickOnce protocol

Supported versions

  • On Windows since 78 or later

Description

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 will be 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 have the option to 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 have the option to disable the ClickOnce protocol with edge://flags/ page.

Disabling ClickOnce may prevent ClickOnce applications (.application files) from launching properly.
