Since the beginning of 2017, Microsoft has committed to release two windows 10 feature updates every year, one in the spring and the other in the autumn, with an interval of six months. The next feature update version 2004 of windows 10 is expected to be released in April / May this year, and Microsoft is currently doing the final repair work.
After the windows 10 build 19041 version update, the windows 10 may 2020 update and Windows Server 2004 search results are displayed in the "get vmhostsupportedversion" command list of windows PowerShell.
From this clue, we can see that the next function update may follow the previous month naming rules and enable the name of May 2020 function update. Of course, if Microsoft chooses to provide the update in April this year, it may enable the name of April 2020, but this is not likely.
