The final version of Windows 11 was accidentally released to PCs that aren't officially supported by Microsoft. Something went wrong.
Hundreds of Windows Insiders were able to upgrade their Windows 10 machines to newer ones, thanks to a mistake that was quickly spotted by users on social media. Microsoft has strict minimum hardware requirements for Windows 11, so the mistake will highlight the company's controversial upgrade policy.
Intel 8th Gen Coffee Lake or Zen 2 are required for Windows 11. This mistaken release is unusual because Microsoft doesn't allow its Windows Insiders to install the operating system on PCs that aren't supported by the company.
Microsoft is looking into the mistake. A bug is being investigated by the right team according to the official Windows Insider account. You should be able to roll back the unexpected upgrade in the settings section of Windows 11 if you were expecting only Release Preview updates for Windows 10.
