Dear Peijlie,
There is currently no official release date for Windows 12.
While there is no confirmed release date from Microsoft, the consensus in the tech community, based on industry trends and insider reports, points to a potential release in the fall of 2025 at the earliest. Initial rumors of a 2024 release are now widely believed to have been referring to the significant Windows 11 24H2 update, which incorporates new AI features.
Here are more detailed answers to your questions:
- Upgrading on Unsupported Hardware Given that your Lenovo ThinkPad T450s is running Windows 11 on unsupported hardware via a workaround, it is highly likely you will face a similar situation with Windows 12. Microsoft is expected to maintain or even increase the strict hardware requirements seen with Windows 11, focusing on modern processors and security features like TPM 2.0.
It is probable that the community of developers and enthusiasts will find methods to bypass these checks for Windows 12, similar to the tools and techniques used for Windows 11. However, this is not guaranteed and running a future operating system on unsupported hardware may lead to instability, and the loss of security and feature updates
Best Regards
