Hello Windows Insiders, Microsoft are announcing Windows 10 version 21H1 as the next feature update for Windows 10.
21H1 is here, Microsoft Win10 19043.844 is online, offers some new features
News from IT House, February 18 Today Microsoft officially released the Windows 10 21H1 version 19043.844 (KB4601382) version for the developer testing and preview channel. Users participating in the Windows 10 test can now go to “Settings> Update and Security” and “Windows Update”, and then choose to download and install the 21H1 update.
According to reports, this version update is bringing many improvements including new features of Windows Hello.
At present, there are few testers for the new version, and the specific new features are unknown. The following is the official update announcement of Microsoft. Welcome to post the new content you find to IT Home.
- Windows Hello multi-camera support allows users to use external cameras when using high-end displays with integrated cameras.
- Windows Defender Program Application Protection performance improvements, including optimizing document opening times.
- When you open a Microsoft Defender Application Protection (WDAG) office document. Then you may experience delays of more than one minute. Which has been fixed. Microsoft said that this happens. When users try to open a file using a universal naming convention (UNC) path or a server message block (SMB) shared a link.
- When users copy files larger than 400 MB. So robocopy performance improves.
- An issue that caused the WDAG container to occupy approximately 1 GB of memory (working set) when the container was inactive.
- Windows Management Instrumentation (WMI) Group Policy Service (GPSVC) provides performance improvements and supports remote work scenarios.
- Fixed an issue that was caused by the slow proliferation of changes made by Active Directory (AD) administrators for user or computer group memberships. However, the access token will be updated. When an administrator uses gpresult / r or gpresult / h to create a report. So this part of the change will not appear.
In addition, this version also includes the following 20H2 improvements (temporary machine translation):
- We fixed the memory leak of Internet Explorer 11, which occurred when you used the Chinese package.
- We fixed an issue with certain COM+ name-specific policies that caused deadlocks in certain applications.
- We fixed an issue that prevented certain Win32 applications from opening as other users when using runas
- We fixed an issue where unexpected screens were displayed during the Windows Out of Box Experience (OOBE).
- When the COM server delivers events to multiple subscribers in parallel, we fixed an issue that could cause a deadlock.
- We fixed an issue where the high dynamic range (HDR) display refresh rate was incorrect in the advanced display settings.
- We fixed an issue that may prevent certain CAD applications from opening if they depend on OpenGL.
- We fixed an issue that may cause flickering in video playback when rendering on some monitors that support low latency.
- We fixed an issue that sometimes prevented string input from the Input Method Editor (IME).
- We fixed an issue where the Desktop Windows Manager (DWM) leaked handles and virtual memory in a remote desktop session and exhausted resources.
- We fixed the issue of stop errors that occurred during startup.
- When you open the “Settings->Accounts->Login Options” page, we fixed an issue that may delay the deployment of Windows Hello for Business (WHfB) certificate trust.
- We fixed an issue that could sometimes prevent certain keyboard keys from working, such as the homepage, Ctrl, or left arrow key. This problem occurs when the Japanese IME input mode is set to Kana.
- We removed the history of previously used pictures from the user account profile.
- After changing the system locale, we fixed the problem of displaying the wrong language on the console.
- We fixed an issue that caused the host process of Windows Remote Management (WinRM) to stop working when formatting messages from the PowerShell plugin.
- We fixed an issue in the Windows Management Instrumentation (WMI) service that caused a heap leak every time security settings were applied to WMI namespace permissions.
- After opening the game with certain hardware configurations, we fixed the issue of screen rendering.
- When User Experience Virtualization (UE-V) is enabled, we improved the startup time of applications with roaming settings.
- We fixed an issue where principals in the trusted MIT realm could not obtain a Kerberos service ticket from an Active Directory Domain Controller (DC). This will happen on devices that include CVE-2020-17049 protection and Windows Update with PerfromTicketSignature configured to 1 or higher. These updates were released between November 10, 2020 and December 8, 2020. If the caller submits a PAC-free ticket-granting ticket (TGT) as an evidence ticket without providing evidence, the ticket acquisition will also fail with the error “USER_NO_AUTH_DATA_REQUIRED KRB_GENERIC_ERROR”.
- We fixed high memory and CPU utilization in Microsoft Endpoint Defender.
- We have enhanced data loss prevention and internal risk management solutions capabilities in Microsoft 365 endpoints.
- We fixed an issue with external cameras that support Windows Hello. By default, when there is an internal Windows Hello camera, Windows Hello will now use the external camera.
- When you try to use Microsoft Edge to open an untrusted webpage or open an untrusted Microsoft Office document, we fixed the display error. The error is “WDAG Report + Container: Error: 0x80070003, Ext Error: 0x00000001”. This issue occurs after installing the .NET update KB4565627.
- We fixed an issue that prevented Wevtutil from parsing XML files.
- When the Elliptic Curve Digital Signature Algorithm (ECDSA) generates an invalid key of 163 bytes instead of 165 bytes, we fixed an issue where errors cannot be reported.
- We added support for using Chrome-based Microsoft Edge as an assigned access single booth application. Now you can also customize the grouping key sequence for a single application booth. For details, see Configure Microsoft Edge kiosk mode.
- We fixed an issue where User Datagram Protocol (UDP) broadcast packets were larger than the maximum transmission unit (MTU). The device receiving these packets discards them because the checksum is invalid.
- We fixed an issue where the WinHTTP AutoProxy service did not comply with the value set for the maximum time to live (TTL) on the proxy automatic configuration (PAC) file. This prevents the cached files from being updated dynamically.
- We have improved the ability of the WinHTTP web proxy auto-discovery service to ignore invalid web proxy auto-discovery protocol (WPAD) URLs returned by the Dynamic Host Configuration Protocol (DHCP) server.
- We display the correct envelope media type as an optional output paper type for the universal print queue.
- When the printer uses the Microsoft Internet Printing Protocol (IPP) class driver, we ended the printer’s random paper size display.
- We enable Windows to retrieve updated printer features to ensure that users have the correct set of optional printing options.
- We have updated the support for punching and labeling positions for print jobs with long-edge first feed direction on some printers.
- We fixed an issue that could cause the IKEEXT service to stop working intermittently.
- We fixed an issue that could prevent Non-Volatile Memory Express (NVMe) devices from entering the proper power state.
- We fixed an issue that could cause Stop Error 7E in the system on servers running Network File System (NFS) services.
- We fixed an issue that prevented the user profile service from reliably detecting slow or fast links.
- We fixed an issue that caused contention for metadata locks when using working folders.
- We added a new dfslogkey as described below:
- The critical path: HKEY_LOCAL_MACHINE/software/Microsoft/dfslog.
- The RootShareAcquire success event field has the following possible values:
- Default value = 1; log is enabled.
- Value other than 1; disable logging.
Announcing Windows 10 Insider Preview Build 19043.844 (21H1). If this key does not exist, it will be created automatically. To be effective, any changes to the dfslog / RootShareAcquire success event in the registry require the DFSS service to be restarted.
- We have updated the Open Mobile Alliance (OMA) Device Management (DM) synchronization protocol to connect client-requested sign-in to the server. The sign-in reason will allow the Mobile Device Management (MDM) service to make better decisions about synchronization sessions. With this change, the OMA-DM service should interact with the Windows OMA-DM client on version 4.0 protocol.
- By default, we turn off token binding in Windows Internet (WinINet).
- We fixed an issue that could prevent the correct Chinese characters from being displayed in apps that allow Chinese characters to be entered automatically. You may need to enter Chinese characters manually. This problem occurs when using Microsoft Japanese Input Method Editor (IME) to enter Chinese characters in these applications.
