Windows 10 Insider Preview Build 19041.208 as new RTM

[German]As of April 30, 2020, Microsoft has released the Windows 10 Insider Preview Build 19041.208 as a new RTM in the Release Preview Ring. This is the 20H1 development branch, which will soon be released as Windows 10 May 2020 Update (Version 2004).

An addendum in the Windows Blog states that build 19041.207 was originally planned as RTM, but now build 19041.208 is used as RTM candidate. Build 19041.208 is rolled out by KB4558244, is cumulative and contains all 20H1 features as well as all fixes published for Windows Insiders in the slow ring in Build 19041.21 to Build 19041.207.

Also fixed is an issue where NPLogonNotify API notifications cannot be sent by the credential provider framework. Note that the May 2020 update is initially only automatically rolled out to a subset of Windows insiders in the Release Preview Preview ring.

All other users in the Windows Insider program who have opted for the Release Preview Ring can manually go to Settings > Update & Security > Windows Update. There you can manually check for updates and then decide to install the offered May 2020 update. Please also note that the new build still has known problems:

• Windows Mixed Reality may not work correctly for many users with the May 2020 update. For those who use Windows Mixed Reality regularly, Microsoft recommends that you do not use the preview of the Windows 10 May 2020 update for the time being. Microsoft is working on a fix that we hope to release in early May.
• Microsoft is aware of an issue where using the Deployment Image Servicing and Management (DISM) tool to repair damage on systems that are running the May 2020 update may not always display the correct status. This will be corrected in a future service release.
• Some applications use the ImeMode property to control the IME (Input Method Editor) mode for individual text input fields to increase input efficiency. This functionality is currently not working correctly in the May 2020 update. For example, a number field does not automatically switch to a mode that is best optimized for Japanese numeric input. This issue will be resolved in a future service update.

To work around this latter problem of the IME mode property for a short time, either switch the input mode manually while typing or select the 'Use previous version' compatibility checkbox for the affected keyboard via Settings > Time & Language.
