HKLM\Software\Policies\Microsoft\Edge\WebView2
DEPRECATED: This policy is deprecated. It is currently supported but will become obsolete in a future release. This policy is deprecated in favor of ChannelSearchKind, which has the same functionality, and will become obsolete in 124 release. The default channel search order is WebView2 Runtime, Beta, Dev, and Canary. To reverse the default search order, set this policy to 1. To set the value for the release channel preference, provide a Value name and Value pair. Set value name to the Application User Model ID or the executable file name. You can use the "*" wildcard as value name to apply to all applications. Example value: Name: *, Value: 1
