UPDATE: We have also released Cumulative Update Build 19035.1000 (KB4533028) today that includes no new changes but helps us test our servicing pipeline for 20H1.

Hello Windows Insiders, today we’re releasing Windows 10 Insider Preview Build 19035 (20H1) to Windows Insiders in BOTH the Fast ring and Slow rings.

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 complete list of new features and updates that have gone out as part of Insider flights for the current development cycle.

NOTE: We are looking to begin releasing new builds from our development branch *very soon*. This means we will be releasing builds to Insiders in the Fast ring from the RS_PRERELEASE development branch again instead of the VB_RELEASE branch. This also means the desktop watermark will be returning with these builds. As is normal with pre-release builds, these builds may contain bugs and be less stable. Now is the time to check your Windows Insider Settings and switch to the Slow ring before if you wish to remain on 20H1.

For Insiders in the Fast ring who have selected to stop getting Insider Preview builds when the next major release of Windows 10 is available under Windows Insider Settings, we will be moving you to the Slow ring as part of honoring this setting. You will remain here until 20H1 is finalized. This only applies to Insiders in the Fast ring who selected this.

General changes, improvements, and fixes for PC

The build watermark at the lower right-hand corner of the desktop is no longer present in this build. This doesn’t mean we’re done…

We’ve completed the experiment related to how we deliver driver updates through Windows Update. Devices that were involved in the experiment will no longer see the Optional Updates link under Settings > Windows Update. This also resolves an issue where after successfully installing printer drivers from the Optional Updates section, the same driver is still showing as available for install. Thanks to the Insiders who have provided feedback on this feature.

We fixed an issue that could result in fingerprint (if enabled) sometimes unexpectedly not being offered as a sign-in option after waking your device from sleep.

We fixed an issue that could result in certain apps not launching the first time you tried after resetting the app via Settings.

Thank you for all the feedback you provided on the Store version of Notepad. At this time, we’ve decided not to roll this out to customers. Insiders may notice some changes as we remove this change from this build: If you pinned Notepad to your Taskbar or Start menu, you will need to re-pin after you upgrade to this new build. If you had certain file types set to open in Notepad by default, you will see a prompt when you try to open files of that type again and will need to re-select Notepad.



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.

Some Insiders have reported when attempting to install recent builds, setup rolls back and returns error code 0xc1900101. In some cases, the update completes successfully on a subsequent attempt. If you are experiencing the issue, please be sure to file feedback in the Feedback Hub.

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

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

We’ve received reports of the Optimize Drives app incorrectly reporting that optimization has never run on SSD devices.
