Microsoft began testing the next big upgrade for Windows 10 back in February. Back then, even the May 2019 Update wasn't released to the public. The Windows maker had said that it has some pretty big plans for this particular update, which require longer testing time.
Since then the company has released the Windows 10 version 1903 to the public and has also started to test Windows 10 October 2019 Update, which is currently in the Slow and Release Preview rings.
But, the next update would be released as a cumulative update and won't be bringing any new features, focusing entirely on performance improvements and stability of the operating system. Looking at the problems that Windows 10 has been experiencing since October 2018, it makes sense for the company to make the operating system bug free before introducing any changes or new features.
Big surprise... The mega Windows 10 2020 to be officially called "Windows 10 May 2020 Update"
While it is yet to be seen if the October 2019 Update will bring that promised stability to the operating system, Microsoft and the Fast ring Insiders continue testing the builds from the Windows 10 20H1 branch. Last year, the H1 update was called the April 2018 Update but this year it was released in May, being called as the May 2019 Update.
The latest preview build has revealed that Microsoft is sticking to the later, planning a May 2020 release for Windows 10 20H1.

The company has also started to release the ISOs for the latest builds to help users clean install Windows 10 2020 on their machines.
