February 25, 2020—KB4537795 (OS Build 17134.1345)

Applies to: Windows 10, version 1803

Release Date:

February 25, 2020

Version:

OS Build 17134.1345

Highlights

• Improves the accuracy of Windows Hello face authentication. 
• Updates an issue that might prevent ActiveX content from loading. 
• Updates an issue that adds an unwanted keyboard layout as the default after an upgrade even if you have already removed it. 
• Updates an issue that prevents some applications from printing to network printers. 

Improvements and fixes

This non-security update includes quality improvements. Key changes include:

• Improves the accuracy of Windows Hello face authentication. 
• Improves Urlmon resiliency when receiving incorrect Content-Length for a PeerDist response. 
• Addresses an issue that might prevent ActiveX content from loading. 
• Addresses an issue that might cause Microsoft browsers to bypass proxy servers. 
• Addresses an issue that adds an unwanted keyboard layout as the default after an upgrade or migration even if you have already removed it. 
• Addresses an issue that causes an error if you open Microsoft OneDrive files on demand when User Experience Virtualization (UE-V) is enabled. To apply this solution, set the following DWORD to 1: “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\UEV\Agent\Configuration\ApplyExplorerCompatFix.” 
• Addresses an issue that generates an “unknown username or bad password” error when attempting to sign in. This occurs in an environment that has a Windows Server 2003 domain controller (DC) and a Windows Server 2016 or later DC. 
• Addresses an issue with sign in scripts that fail to run when a user signs in or signs out. 
• Addresses an issue that continues to collect IsTouchCapable and GetSystemSku data when they should no longer be collected. 
• Provides live response capability that gives Security Operations (SecOps) immediate access to compromised machines using the Microsoft Defender Advanced Threat Protection (ATP) console (Microsoft Defender Security Center). 
• Improves the accuracy of detection in Microsoft Defender ATP Threat & Vulnerability Management. 
• Addresses an issue that might cause Direct Access servers to use a large amount of non-paged pool memory (pooltag: NDnd). 
• Addresses an issue in which the WinHTTP AutoProxy service does not comply with the value set for the maximum Time To Live (TTL) on the Proxy Auto-Configuration (PAC) file. This prevents the cached file from updating dynamically. 
• Addresses an issue that prevents some applications from printing to network printers. 
• Addresses an issue that prevents the Background Intelligent Transfer Service (BITS) from downloading files; the error is “0x80190191.” 
• Addresses an issue that causes the Windows firewall to drop network traffic from Modern apps, such as Microsoft Edge, when you connect to a corporate network using a virtual private network (VPN). 
• Addresses an issue that intermittently generates Online Certificate Status Protocol (OSCP) Responder audit events (5125) to indicate that a request was submitted to the OCSP Responder Service. However, there is no reference to the serial number or the domain name (DN) of the issuer of the request. 
• Addresses an issue that causes queries against large keys on Ntds.dit to fail with the error, “MAPI_E_NOT_ENOUGH_RESOURCES.” This issue might cause users to see limited meeting room availability because the Exchange Messaging Application Programming Interface (MAPI) cannot allocate additional memory for the meeting requests. 
• Addresses an issue that corrupts a log file when a storage volume is full and data is still being written to the Extensible Storage Engine Technology (ESENT) database.
• Addresses an issue with certificate validation that causes Internet Explorer mode in Microsoft Edge to fail.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.

February 25, 2020—KB4537806 (OS Build 14393.3542)

Applies to: Windows 10, version 1607/Windows Server 2016

Release Date:

February 25, 2020

Version:

OS Build 14393.3542

Highlights

• Updates an issue that prevents some applications from printing to network printers. 

Improvements and fixes

This non-security update includes quality improvements. Key changes include:

• Addresses an issue that might cause Microsoft browsers to bypass proxy servers. 
• Addresses an issue that propagates shared folder permissions incorrectly to parent folders after an administrator makes changes on the host system to shared subfolders that are not in the Users directory. 
• Addresses an issue in which re-running PowerShell workflows might fail with compilation errors for long sessions. 
• Improves Event Forwarding scalability to ensure thread safety and increase resources. 
• Addresses an issue that generates an “unknown username or bad password” error when attempting to sign in. This occurs in an environment that has a Windows Server 2003 domain controller (DC) and a Windows Server 2016 or later DC. 
• Addresses an issue that causes Transport Layer Security (TLS) sessions to fail with the error, "The request was aborted: Could not create SSL/TLS secure Channel." 
• Addresses an issue that prevents some applications from printing to network printers. 
• Addresses an issue that prevents the Network Policy Server (NPS) accounting feature from functioning. This occurs when NPS is configured to use SQL for accounting with the new OLE (compound document) database driver (MSOLEDBSQL.dll) after switching to TLS 1.2. 
• Addresses an issue that causes Security Assertion Markup Language (SAML) errors and loss of access to third-party apps for users who do not have multi-factor authentication (MFA) enabled. 
• Addresses an issue that intermittently generates Online Certificate Status Protocol (OSCP) Responder audit events (5125) to indicate that a request was submitted to the OCSP Responder Service. However, there is no reference to the serial number or the domain name (DN) of the issuer of the request.
• Addresses an issue with the spell checker in RemoteApp. This issue prevents the spell checker from using the locale language the user selects when there is a mismatch between the locale setting and the keyboard layout of the local or client machine. For example, the issue occurs if using a Dutch locale language with the United States-International keyboard layout; the spell checker incorrectly uses the English language instead of the locale language (Dutch) configured in the OS.
• Addresses an issue with certificate validation that causes Internet Explorer mode in Microsoft Edge to fail.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.
