Windows 20H2 ve 21H1 sürümleri Windows 11 olmayacak, çünkü bu sürümler destek sonuna ulaştı. Windows 11'in son sürümleri 22H2 ve 23H2'dir ve bunlar hala desteklenmektedir.
Windows 10, sürüm 20H2 artık desteklenmemektedir. Bu sürüm, 10 Mayıs 2022 tarihinde hizmet sonuna ulaşmıştır ve güvenlik güncelleştirmelerini almamaktadır.
Windows 11, sürüm 21H2 artık kullanılmamalıdır, çünkü 10 Ekim 2023 tarihinde hizmet sonu ulaşmıştır. Bu tarihten sonra, 21H2 çalıştıran sistemler güvenlik güncelleştirmeleri ve yeni özellikler içeren toplu güncellemeler almayacaktır.
