Great news! Build 15042 for PC has been released for Fast Ring insiders. Note: this is only for x64 PC’s and 32 bit PC’s will be blocked as there is a bug for 32 bit.
Today we are excited to be releasing Windows 10 Insider Preview Build 15042 for PC and Build 15043 for Mobile to Windows Insiders in the Fast ring. We have discovered a bug that impacts our ability to release this build to PCs running 32-bit (x86) versions of Windows 10 Insider Preview builds. Because the majority of Insiders in the Fast ring have PCs running 64-bit (x64) – we decided to go ahead and release this build with 32-bit PCs blocked until our next flight. Also – please read the known issues below.
