KB5018499 Windows 11 Insider Beta Build 22621.870 and 22623.870

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 22621.870 and Build 22623.870 (KB5018499) to the Beta Channel.

Build 22623.870 = New features rolling out.
Build 22621.870 = New features off by default.

REMINDER: Insiders who were previously on Build 22622 will automatically get moved to Build 22623 via an enablement package. The enablement package artificially increments the build number for the update with new features getting rolled out and turned on to make it easier to differentiate from devices with the update with features off by default. This approach is being used for the Beta Channel only and is not indicative of any changes or plans for final feature rollouts.

Insiders who landed in the group with new features turned off by default (Build 22621.xxxx) can check for updates and choose to install the update that will have features rolling out (Build 22623.xxx).

What’s new in Build 22623.870

Changes and Improvements in Build 22623.870

[Taskbar]

Based on your feedback, we’ve added Task Manager to the context menu when right-clicking on the taskbar. We are beginning to roll this out, so the experience isn’t available to all Insiders in the Beta Channel just yet.

[Tablet-optimized taskbar]

NOTE: These fixes will only show if tablet-optimized taskbar is enabled on your device. Tablet-optimized taskbar is still rolling out to Windows Insiders and not yet available for everyone.

Improved how touch gestures and their animations with the tablet-optimized taskbar work with the touch keyboard.

[System Tray Updates]

NOTE: These fixes will only show if tablet-optimized taskbar with System Tray updates is enabled on your device. Tablet-optimized taskbar and System Tray is still rolling out to Windows Insiders and not yet available for everyone.

Fixed an issue causing explorer.exe to crash when dragging icons in the system tray.

Fixes for BOTH Build 22621.870 & Build 22623.870

New! We added improvements to the Microsoft Account experience in Settings. For instance, you can manage your Microsoft One Drive subscription and related storage alerts.
New! We added a new consent form for those of you enrolled in Windows Hello Face and Fingerprint. You have new choices for your biometric data. You can keep storing your biometric data or open Settings to delete the data if you have not used your face or fingerprint for authentication in over 365 days. You also have these options if you upgraded to Windows 11 and have not yet seen the new Hello Learn More Privacy text.
New! We enhanced search visual treatments on the taskbar to improve discoverability. This is available to a small audience initially and deploys more broadly in the months that follow. Some devices might notice different visual treatments as we gather feedback. To learn more about why you might be seeing these changes, see Search for anything, anywhere.
We updated DriverSiPolicy.p7b for the Windows kernel vulnerable driver blocklist. This update includes drivers that are vulnerable to Bring Your Own Vulnerable Driver (BYOVD) attacks.
We extended original equipment manufacturer (OEM) control of Hypervisor-protected Code Integrity (HVCI) enforcement for targeted hardware configurations.
We fixed an issue that affects the Microsoft Azure Active Directory (AAD) Application Proxy connector. It cannot retrieve a Kerberos ticket on behalf of the user. The error message is, “The handle specified is invalid (0x80090301).”
We fixed an issue that affects cached credentials for security keys and Fast Identity Online 2.0 (FIDO2) On hybrid domain-joined devices, the system removes these cached credentials.
We fixed an issue that might cause vertical and horizontal line artifacts to appear on the screen.
We fixed an issue that affects title bars when you use third-party tools to customize them. The title bars did not render. This update ensures that title bars render; however, we cannot guarantee all text customizations will work as before.
We fixed an issue that might fail to sync the audio when you record game play using the Xbox Game Bar.

Known issues

[General]

We’re looking into reports that audio stopped working for some Insiders in recent Beta Channel builds.

[Tablet-optimized taskbar]

The taskbar sometimes flashes when transitioning between desktop posture and tablet posture.
The taskbar takes longer than expected to transition to the touch-optimized version when switching between desktop posture and tablet posture.
When using the bottom right edge gesture to see Quick Settings, the taskbar sometimes stays stuck in the expanded state, instead of dismissing to collapsed state.

About the Beta Channel

The Beta Channel will be the place we preview experiences that are closer to what we will ship to our general customers. Because the Dev and Beta Channels represent parallel development paths from our engineers, there may be cases where features and experiences show up in the Beta Channel first. However, this does not mean every feature we try out in the Beta Channel will ship. We encourage Insiders to read this blog post that outlines the ways we’ll try things out with Insiders in both the Dev and Beta Channels.
