Once an Insider has updated their PC to Windows 10, version 22H2, they will continue to automatically receive new service updates via Windows Update (the typical monthly update process). This means that Insiders who are currently in the Release Preview Channel can go to Settings and then Windows Update to download and install Windows 10, version 22H2. Then you can search for the relevant update KB5015878 via Windows Update. However, the machine must be included in the Release Preview Channel of the Insider program. Microsoft also makes this build available to all Windows Insiders in the Release Preview Channel.

This support offering is designed to help resolve issues with enterprise-specific scenarios and is limited to Windows 10 Pro, Enterprise and Education editions. Should any issues arise, IT administrators in these organizations can request free Microsoft support.
