如何检测IE“更新版本”

Question

After IE was updated to Update Versions 11.0.35, the timings of "keydown" event and DOM mutation were changed when Hangul is edited in content editable blocks.

How can I detect IE Update Versions in Javascript?

(IE ScriptEngineMajor/Minor/BuildVersion functions are not useful because it is different even in case of same "Update Versions")

function getInternetExplorerVersion()
// Returns the version of Windows Internet Explorer or a -1
// (indicating the use of another browser).
{
    var rv = -1; // Return value assumes failure.
    if (navigator.appName == 'Microsoft Internet Explorer') {
        var ua = navigator.userAgent;
        var re = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
        if (re.exec(ua) != null)
            rv = parseFloat(RegExp.$1);
    }
    return rv;
}

function checkIEVersion() {
    var msg = "You're not using Windows Internet Explorer.";
    var ver = getInternetExplorerVersion();
    if (ver > -1) {
        console.log(ver);
    }
}
