Remove windows is not genuine notification

অনেক সময় আমাদের Windows 7-এর Screen এ Windows is not genuine Notification দেখতে পাই। আর এটা সাধারনত হয় যখন আমাদের Windows-এ Update Option চালু থাকে এবং ইন্টারনেট চালু থাকে। 


যখন এমন হয় তখন অনেকেই হয়তো নতুন করে Windows Setup করেছেন। তো ভবিষ্যতে যদি কেউ এমন সমস্যায় পরেন তাহলে নিচের প্রক্রিয়া অনুসরন কইরেন আসা করি সমস্যার সমাধান পাবেন। 

Start=>All Programs=>Accessories=>Command Prompt-এ ডান বাটন এ ক্লিক করে Run as Administrator করুন। 

এর পর Command Prompt-টি চালু হলে সেখানে শুধু "SLMGR –REARM" টাইপ করে Enter চাপুন। 

কাজ শেষ এখন একটা Restart- দিন।
