Détecter Windows 11 en JavaScript :

async function isWin11orLater() {

    let reponse = false;

    if (navigator && navigator.userAgentData) {
                await navigator.userAgentData.getHighEntropyValues(["platformVersion"])
                .then(ua => {
                    if (navigator.userAgentData.platform === "Windows") {
                        const majorPlatformVersion = parseInt(ua.platformVersion.split('.')[0]);
                        if (majorPlatformVersion >= 13) {
                            //alert("Windows 11 or later");
                            reponse = true;
                        } else {
                            reponse = false;
                        }

                    }

                    }
                });
