Windows 10 May 2020 Update, version 2004 will be released to OEMs on May 5, and developers will receive an update on May 12. General availability is scheduled for May 28, 2020.
Yesterday, Microsoft released Windows 10 Build 19041.208 with the KB4558244 update on the Release Preview channel. This build is the new RTM candidate for the spring Windows 10 May 2020 Update. The developers made available build 19041 (20H1) on the Late access channel back in December and since then have been serving Windows 10, version 2004 with cumulative updates, preparing the operating system for a stable release.
Since the new feature update has already received many fixes using cumulative patches, Microsoft was ready to release a new version for all users in early May, preferably on Tuesday patches. But this does not seem to happen. Mary Joe Foley, a journalist at ZDnet, says the Windows 10 May 2020 Update may be publicly available on May 28.
Initially it was reported that the update was scheduled for May 12, and the final assembly was due out for OEMs and developers on April 28. However, these dates were rescheduled due to a zero-day exploit that Microsoft wants to fix. In line with the revised deadlines, Windows 10, version 2004 will be released to OEMs on May 5, and developers will receive an update on May 12. General availability is scheduled for May 28, 2020. Again, Microsoft has not officially announced this, and these dates may change again.
Since several cumulative updates have already appeared in the Windows 10 May 2020 Update, and in the future it will most likely receive several more fixes, including fixes for detected vulnerabilities, then Windows 10, version 2004 will most likely come out more stable and will not contain critical errors at startup.
