Also, devices that use the same device or hardware ID (for example - 2 identical Flash Disks made by the same manufacturer) will still function if one of them was plugged-in prior to the configuration of this setting.

yukarıdaki kodu .txt dosyasına ekleyıp "%systemroot%\inf\"  konumuna kopyalayıp istenilen "OU'ya" sağ tıklayıp "create a gpo in this domain and link it here"  diyerek gpo'ma isim verip editleyerek gerekli policy ayarlarını uyguluyorum. sonrasında ise cmd'den gpupdate /force edip geçerli OU'ya ağ yolundan gitmesini sağlıyorum, OU'nun içerisinde bulunan herhangibir client'a girerek iki defa gpupdate /force edip policy'm uygulandımı diye kontrol ediyorum gpresult /r diyerek fakat policy hiçbir şekilde uygulanmadıgını görüyorum, fakat 2 - 3 gün belli bir süresi yok biraz beklediğimde uygulandıgını görüyorum bunun nedeni nedir? İSTEDİĞİM ZAMAN POLICY'İ NEDEN UYGULAMIYOR ANLIK OLARAK ? SORUN NEREDEN KAYNAKLIDIR YARDIMCI OLURMUSUNUZ ???

ÇÖZEMEDİM BİR TÜRLÜ, YARDIMLARINIZA İHTİYACIM VAR.
