Microsoft is rolling out Windows 10 20H1 Build 18936 to Windows Insiders in the Fast ring, with the build including support for passwordless authentication, Phone screen support for more Surface devices, as well as various fixes.
If you are a Windows Insider in the Fast ring, you can update to Insider Preview Build 18936 by going into Settings -> Update & Security -> Windows Update and then checking for new updates.
Below we have outlined some of the major changes in this build. To see the full release notes, you can read the blog post.
Passwordless sign-in support for Microsoft accounts
Windows 10 Insiders can now use passwordless authentication with their Microsoft accounts after enabling it from Settings > Accounts > Sign-in options and toggling on the Make your device passwordless option.
“Enabling passwordless sign in will switch all Microsoft accounts on your Windows 10 device to modern authentication with Windows Hello Face, Fingerprint, or PIN,” says Microsoft.
Insiders will be walked through the Windows Hello setup after enabling the new feature on the next sign-in and can watch a short video detailing how a Windows Hello PIN improves their account security.
Seeing that Microsoft is currently rolling out passwordless authentication to a small number of Windows Insiders, the feature might not be available for all users in the Settings dialog until it will be pushed to all users.
Microsoft also announced today the public preview support for FIDO2 security keys in Azure Active Directory, a new capability that provides passwordless authentication for Azure AD users.
Phone screen is now compatible with more Surface devices
The phone screen feature can now be used by Windows 10 Insiders on more PC models after the latest driver update in the Windows Insider rings (Marvell 15.68.17013.110) added support for the following Surface devices: Surface Laptop, Surface Laptop 2, Surface Pro 4, Surface Pro 5, Surface Pro 6, Surface Book, and Surface Book 2.
Create events and reminders from the taskbar
For Windows Insiders who want to add new events while going through the calendar flyout, Windows 10 20H1 Build 18936 now comes with the option to quickly add new reminders and events.
This new option will be available when clicking on the taskbar date, right under the full sized calendar that will pop-up above the Windows taskbar.
General changes, improvements, and fixes for PC
- We fixed an issue that was causing failures when installing games via the Xbox app in the previous flight.
- We fixed an issue resulting in the Photos live tile potentially drawing outside the bounds of the tile.
- We fixed an issue where the emoji panel would crash when high contrast was enabled.
- We updated the disk type text in Task Manager’s Performance tab to now match the size of the other subtext on that tab.
- We fixed an issue resulting in items not launching in the foreground when selected from the taskbar jump list of certain apps.
- We fixed an issue that could result in the virtual desktop thumbnail in task view not updating after moving a window to a different desktop.
- Running Windows Sandbox no longer requires Administrator privilege.
- We fixed an issue resulting in the composition string not being shown in certain apps when typing with the Japanese IME.
- We fixed an issue resulting in certain apps crashing when typing with the Chinese Pinyin IME.
- We fixed an issue resulting in certain games unexpectedly just showing a black screen when run in full screen mode on some devices recently.
- A limited number Insiders attempting to install Build 18936 may experience install failures with error code c1900101 due to a compatibility bug with a storage driver on their device. The device will attempt to install, fail, and successfully roll back to the currently installed build on the device. Attempted re-tries to install the build, either manual or automatic, will not bypass this issue. A fix is forthcoming, but there are no known workarounds currently. Note: By default, the update will attempt to install (3) times. Users may pause updates if they experience this issue and want to bypass the re-try attempts.
- Insiders may notice some changes in Magnifier with today’s build. These aren’t quite ready yet for you to try, but we’ll let you know once they are in an upcoming flight.
- There has been an issue with older versions of anti-cheat software used with games where after updating to the latest 19H1 Insider Preview builds may cause PCs to experience crashes. We are working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of running into this issue, please make sure you are running the latest version of your games before attempting to update the operating system. We are also working with anti-cheat and game developers to resolve similar issues that may arise with the 20H1 Insider Preview builds and will work to minimize the likelihood of these issues in the future.
- Some Realtek SD card readers are not functioning properly. We are investigating the issue.
- Tamper Protection may be turned off in Windows Security after updating to this build. You can turn it back on. In August, Tamper Protection will return to being on by default for all Insiders.
