Microsoft has abandoned its October deadline for Windows 10, affecting approximately 700 million users who can choose to remain on Windows 10 or upgrade to Windows 11. About 400 million users are eligible for a free upgrade to Windows 11, while around 240 million cannot upgrade due to hardware requirements. Users can extend support for Windows 10 until October 2026 through cloud backup, redeeming rewards points, or paying a nominal fee. Windows 10 will receive security updates for the next 12 months, but Windows 11 offers enhanced security features. Microsoft emphasizes the importance of upgrading to Windows 11 for better security. Concerns exist about user inertia and the potential slowdown in upgrade momentum. The extended support tool will soon be available to all users, and those unable to upgrade are advised to utilize it.
