According to a report by Windows enthusiast PhantomOcean3, Microsoft originally planned to release the Win11 Build 23526 preview update for Windows Insider members of the Dev channel today and planned to release the ISO image simultaneously.
PhantomOcean3 said that Microsoft had released the Build 23526 preview ISO image on the Windows Insider page on time, but quickly withdrew it a few minutes later.
PhantomOcean3 said that due to the rapid withdrawal of Microsoft, the ISO image was not downloaded in time, and it is impossible to know the changes of the new version.
Microsoft officials did not respond to the reason for this withdrawal. Many foreign technology media have asked Microsoft for confirmation, but the official did not respond.
