Microsoft recently released code from the Windows 10 2020 H1 branch to testers last month, which left many wondering why Microsoft wasn't releasing code from the 19H1 update. Some thought Microsoft might be moving to one Windows 10 feature update per year, while others thought the marriage of Chromium and Edge might be creating a delay. However, ZDNet's sources refuted both those claims, They say that, as a result of the Azure development team catching up to the latest version of Windows core OS, the Windows core team is skipping the June Windows update and is instead focusing on the Windows 10 20H1 release. In a nutshell, ZDNet thinks that the Windows 10 19H2 update might appear to be a relatively minor update, but that's only the result of some one-time development shifts, not a release pattern Microsoft wants to stick to in the future. This 19H2 release might appear like a more minor update, but only to those paying close attention. Does this mean Microsoft is going to move to a major/minor schedule with Windows 10 feature releases moving forward? I hear the answer is no. This year is just a messy one-off, sources of mine say. Microsoft's plan remains to continue to roll out two new Windows 10 feature updates every year (over the howls of protest of many business and consumer users). If all the stars align,the 20H1 release will be built on the Windows 10 core OS Vibranium platform which engineering will deliver internally to various Microsoft teams as of December 2019. If all goes as planned, the Windows 10 20H2 release will be built on the Windows 10 core OS platform delivered internally in June 2020 (which is codenamed "Manganese").
