Hello Windows Insiders, today we’re releasing Windows 10 Insider Preview Build 19551.1005 to Windows Insiders in the Fast ring.

If you want a complete look at what build is in which Insider ring, head over to Flight Hub. You can also check out the rest of our documentation here, including a list of new features and updates.

Other updates for Insiders

We’re continuing to look at ways we can improve the update experience on Windows 10 PCs for our customers. As part of this effort, we are conducting an experiment related to how we deliver driver updates through Windows Update. During this experiment, drivers categorized as “optional” will not be automatically downloaded and installed on Windows Insider’s PCs running Build 19536 and newer. To install any new optional drivers available for a PC that’s involved in this experiment (including drivers for new devices that might get plugged in to a PC), Insiders can go to Settings > Update & Security > Windows Update > View optional updates and manually download these drivers. This experiment will be running now through March 5th, 2020.

General changes, improvements, and fixes for PC

We fixed an issue resulting in snipping not working on secondary monitors.

Thank you for reporting that the Optimize Drives Control Panel was incorrectly showing that optimization hadn’t run on some devices. We’ve fixed it in this build.

We’ve fixed an issue causing Remote Desktop Connection crashes when attempting to connect to multiple sessions.

We’ve made a server-side fix to address the issue causing Narrator Home to crash when selecting the “What’s New” button in Narrator Home.

We fixed an issue that could result in the language defaults listed at the top of Language Settings unexpectedly being blank.

We’ve done some work to help address feedback reports that screenshots (WIN+Shift+S) pasted into Outlook would be unexpectedly large.

We fixed an issue where, if you’d changed the candidate pane font for the Pinyin IME, it would be reset back to default after you reboot your PC.

We fixed an issue resulting in the “Safely Remove Hardware” icon in the notification area sometimes unexpectedly drawing in white (making it unreadable) when using light theme.

Known issues

BattlEye and Microsoft have found incompatibility issues due to changes in the operating system between some Insider Preview builds and certain versions of BattlEye anti-cheat software. To safeguard Insiders who might have these versions installed on their PC, we have applied a compatibility hold on these devices from being offered affected builds of Windows Insider Preview. See this article for details.

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. Users of legacy Microsoft Edge will not be affected. NVAccess has released a beta of NVDA that resolves the known issue with Edge. Further information can also be found in the In Process blog post that goes into more detail about the beta.

The cloud recovery option for Reset this PC isn’t working on this build. Please use the local reinstall option when performing Reset this PC.

We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.

We’re investigating reports that some Insiders are unable to update to newer builds with error 0x8007042b.

We’re looking into reports that some Insiders are unable to update to newer builds with error 0xc1900101.

We’re looking into reports of certain external USB 3.0 drives not responding with Start Code 10 after they’re attached.

The Documents section under Privacy has a broken icon (just a rectangle).

The IME candidate window for East Asian IMEs (Simplified Chinese, Traditional Chinese, and the Japanese IME) may not open sometimes. We are investigating your reports. As a workaround if you encounter this, please change the focus to another application or editing area and back to the original and try again. Alternatively, you can go to Task Manager and end the “TextInputHost.exe” task from the Details tab, and it should work afterwards.

[ADDED] There is an issue impacting ARM64 devices from updating to this build successfully. A fix will be coming soon in a future flight.

Halting Project Catnip

We’re no longer planning to do external testing or a public release of our “Project Catnip PWA” for the Windows Insider Program. Due to some technical limitations, we were not going to be able to offer the experiences we wanted to for Insiders through the PWA. We’re still looking at solutions for some of the features we investigated in the PWA. Thank you as always for your enthusiasm.

Thanks,

BLB
