Microsoft have pushed an update to the Windows 10 May 2020 Update to the release preview ring. KB4558244 takes the build to 19041.208 and has just the one fix:

  • We fixed an issue that fails to send NPLogonNotify API notifications from the credential provider framework.

The update was release to the slow ring last week as Microsoft get close the general release of the May 2020 Update / version 2004 (codenamed 20H1). Microsoft are targeting May for the update so I expect it to go to “seekers” (people that check for updates) in the next few weeks.

Windows Mixed Reality users should hold off getting the update until they release a patch along with the general release, but when they do get the update there are some nice improvements.

Know issues:

  • Windows Mixed Reality may not work correctly for many users on the May 2020 Update. If you regularly use Windows Mixed Reality, we recommend holding off taking the May 2020 Update via Release Preview for now. We are working on a fix which we hope to release in early May.
  • We are aware of an issue where using the DISM (Deployment Image Servicing and Management) tool to repair corruption on systems running the May 2020 Update does not always report the correct status. This will be fixed in an upcoming servicing release.
  • Some apps utilize the ImeMode property to control the IME (Input Method Editor) mode for individual text entry fields to increase typing efficiency. This functionality does not work correctly currently in the May 2020 Update. For example, a number field will not automatically switch to a mode that is best optimized for Japanese numerical input. This issue will be fixed in an upcoming servicing update. To work around this issue in the short term, either manually switch the input mode when typing, or set the Compatibility ‘Use previous version’ checkbox for the impacted keyboard via Settings > Time & Language.
