How can I detect if Microsoft Edge is installed?

Question

I'm writing a windows form application (c#) and I need to detect whether the user have "Microsoft-Edge" installed in his/her machine or not.

I'm currently using this registry location:

[HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\PackageRepository\Packages\Microsoft.MicrosoftEdge_20.10240.16384.0_neutral__8wekyb3d8bbwe]
"Path"="C:\\Windows\\SystemApps\\Microsoft.MicrosoftEdge_8wekyb3d8bbwe"

With a regex after the "Microsoft.MicrosoftEdge". If the "path" exist then I know edge is installed.

Is there a better way to detect edge? would it be better if I detect that I'm running on Windows 10 and by default Win10 come with edge? What is the best way for that?

In case you want to have a small program getting that version number:

static void Main(string[] args)
    {
        string EdgeVersion = string.Empty;
        //open the registry and parse through the keys until you find Microsoft.MicrosoftEdge
        RegistryKey reg = Registry.ClassesRoot.OpenSubKey(@"Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\PackageRepository\Packages");
        if (reg != null)
        {
            foreach (string subkey in reg.GetSubKeyNames())
            {
                if (subkey.StartsWith("Microsoft.MicrosoftEdge"))
                {
                    //RegEx: (Microsoft.MicrosoftEdge_)(\d +\.\d +\.\d +\.\d +)(_neutral__8wekyb3d8bbwe])
                    Match rxEdgeVersion = null;
                    rxEdgeVersion = Regex.Match(subkey, @"(Microsoft.MicrosoftEdge_)(?<version>\d+\.\d+\.\d+\.\d+)(_neutral__8wekyb3d8bbwe)");
                    //just after that value, you need to use RegEx to find the version number of the value in the registry
                    if ( rxEdgeVersion.Success )
                        EdgeVersion = rxEdgeVersion.Groups["version"].Value;
                }
            }
        }

        Console.WriteLine("Edge Version(empty means not found): {0}", EdgeVersion);
        Console.ReadLine();
    }

Thank you for the registry link for finding the version number.
