What is the cheapest legitimate way to buy Windows 11?
Short answer
An OEM key from a Microsoft-authorised reseller is typically 40–60% cheaper than Microsoft Store retail and is legally transferable once. Expect to pay around €30–€40 for Home and €50–€70 for Pro from a reputable reseller with money-back guarantee.
The longer explanation
يبلغ سعر النسخة في متجر Microsoft نحو 145 يورو لإصدار Home و259 يورو لإصدار Pro. أما مفاتيح OEM التي توزعها Microsoft على مجمّعي الأنظمة فهي نفس رمز المنتج، لكنها مرتبطة بلوحة أم واحدة — صالحة تمامًا للأفراد وأرخص بنسبة 40–60%. البائع الموثوق يُصدر فاتورة ضريبية وسياسة استبدال مكتوبة ونافذة استرداد.
تجنّب الإعلانات التي تقل عن 10 يورو — فهي في الغالب مفاتيح MAK جماعية مسروقة من اتفاقيات الشركات وتُلغيها Microsoft على دفعات. إذا بدا السعر غير معقول، فتحقق من العنوان القانوني للبائع وشروط الاسترداد قبل الدفع.
