Despite the ongoing COVID-19 outbreak, we are getting Build 2020 in May. However, it won't be a major conference in Microsoft's Redmond base but instead a virtual event. That's fine as it still means the company can make all announcements. One of them is expected to be Windows Core OS, which has just resurfaced.
If you're unfamiliar with Windows Core OS (WCOS), it is a modular version of Windows 10. By creating a modular Windows experience, Microsoft can put the full power of Windows 10 on any device. WCOS will provide Microsoft with a platform that will work on mobile devices and PCs alike. Users on smartphones will be able to receive a full Windows 10 PC-quality experience.
It's not much of a secret the platform exists, although Microsoft has never officially confirmed it. The company was predicted to be preparing a WCOS launch at its Surface event last October. However, the company instead revealed Windows 10X.
While there was some pre-event confusion around whether 10X and WCOS were the same, they are different projects. Windows 10X is one implementation of WCOS designed for dual screen devices like the Surface Neo.
Looking at the Geekbench results, Windows Core OS was running on a virtual machine powered by an Intel Core i5 CPU. The 64-bit operating system is seemingly now in active testing and could mean an official announcement is close. Build 2020 would be the ideal venue for that announcement.
