As the Windows 20H1 development approaches its completion, insider preview build 19041.208 is now live in the Slow ring.

The build does not provide any new app features or enhancements. Instead, it offers a fix that a previous update, build 19041.207, did not include.

Microsoft released build 19041.207 to the Release preview ring last week. It said that the build would be the last as the company prepares to push out the much-anticipated Windows 10 May 2020 Update (20H1).

Little wonder the latest update has no new features.

Upgrade now to address an NPLogonNotify API bug

Win32 app Developers can breathe a sigh of relief as Microsoft said that it resolved a problem with NPLogonNotify API notifications.

The function in question is critical to credential management.

In a typical Winlogon process, the Multiple Provider Router (MPR) invokes the API to tell the credential manager (CM) that a logon event has occurred. Next, the CM sends back a logon script.

With this update, sending NPLogonNotify alerts from the credential provider framework should work as expected.

It is not surprising that preview build 19041.208 fixes only one bug. The reason for this is that the update includes numerous solutions that Microsoft released with build 19041.207 last week.

So if, for some reason, you did not install build 19041.207, try installing the latest update to fix other Windows 10 PC bugs like:

  • The unexpected crashing of the Remote Procedure Call (RPC) service.
  • The malfunctioning of the Device Enrollment Status Page (ESP) on managed devices.
  • The malfunctioning of the rear camera flash on devices with that feature.
  • The update also included security patches for multiple Windows 10 applications, systems, and features.

The persistent screen reader issue

The release notes for 20H1 build 19041.208 include some bad news for Chromium-based Edge browser users with visual impairment.

We are aware Narrator and NVDA users that seek the latest release of Microsoft Edge based on Chromium may experience some difficulty when navigating and reading certain web content. Narrator, NVDA and the Edge teams are aware of these issues.

Meanwhile, affected users can still use the screen readers with the old Microsoft Edge. The legacy version of the browser does not seem to have compatibility issues with Narrator or NVDA.

Also, NVAccess published a solution to this particular Edge problem.

Users expect Microsoft to push the Windows 10 May 2020 Update very soon. The final version will include major upgrades to the OS, apps, and features.
