There is no official Microsoft announcement that Windows 12 was scheduled for autumn 2024, and there is no official statement that such a release was cancelled. The available Microsoft guidance indicates that Windows 11 remains the current Windows version and continues to receive ongoing yearly updates.
For the support question: the context does not support a blanket rule that a new Windows version released on October 5, 2021 would automatically be supported for 10 years. The documented lifecycle shown here is version- and edition-specific:
- Windows 11 feature updates are serviced once per year.
- Windows 11 Enterprise, Enterprise multi-session, Education, and IoT Enterprise editions receive 36 months of servicing per release.
- Windows 11 Pro, Pro Education, Pro for Workstations, Home, and SE receive 24 months of servicing per release.
- Windows 10 version 22H2 is the last Windows 10 feature update and is serviced through October 14, 2025.
So, support duration depends on the specific product and edition, not simply the release date alone.
