Check out the highlights of what update KB5006738 brings below.

Here is the full changelog provided by Microsoft for update KB5006738.

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

  • Addresses an issue that prevents you from accessing the pre-provisioning page during the out-of-the-box experience (OOBE). This issue occurs when the credentials page for signing in to Azure Active Directory is displayed and you press the Windows key five times.
  • Adds a feature that facilitates certain data transfers between browsers.
  • Addresses an issue with assigned access kiosks that are configured with Microsoft Edge as a kiosk app. Sometimes these kiosks may not restart Microsoft Edge if users close the browser window.
  • Addresses an issue in which using App-V intermittently causes black screens to appear when signing in to the credentials page.
  • Addresses an issue that could prevent the display of closed captions for some video applications and video streaming sites.
  • Addresses an issue that prevents Windows 10 Virtual Private Network (VPN) users from connecting to Windows Server 2019 Routing and Remote Access Service (RRAS) servers.
  • Addresses an issue that prevents Software-Defined Networking (SDN) virtual machines from functioning when you configure Generic Routing Encapsulation (GRE) VPN bandwidth throttling.
  • Addresses a primary refresh token (PRT) update issue that occurs when VPN users sign in using Windows Hello for Business when the VPN connection is offline. Users receive unexpected authentication prompts for online resources configured for User Logon Frequency (SIF) in Azure Active Directory-Conditional Access.
  • Addresses an issue that causes Windows to enter BitLocker recovery after a maintenance update.
  • Fixes an issue that could cause Kerberos.dll to stop working within the Local Security Authority Subsystem (LSASS) service. This occurs when LSASS is processing concurrent User-to-User (U2U) User-to-User (S4U) service requests for the same client user.
  • Addresses a code integrity issue that could cause a memory leak.
  • Improves the ability of Microsoft Defender for Endpoint to identify and intercept ransomware and advanced attacks.
  • Addresses an issue in OOBE that could cause Windows AutoPilot provisioning to fail.
  • Addresses an issue that prevents Kana input mode users from inserting a question mark (?) Using the Shift-0 key combination.
  • Addresses an issue that sometimes causes the lock screen to appear black if you set up a slideshow.
  • Resolves a reliability issue with LogonUI.exe, which affects the rendering of network status text on the credentials screen.
  • Addresses an issue that causes Server Message Block (SMB) query directory requests to fail when the buffer size is large.
  • Fixes a memory leak issue in lsass.exe on domain controllers in the forest root domain which occurs when you have multiple forests and multiple domains in each forest. SID-Name mapping functions leak memory when a request comes from another domain in the forest and crosses forest boundaries.
  • Addresses an issue with the virtual machine (VM) load balancing feature, which ignores the fault domain of a site.
  • Addresses a known issue that could prevent the successful installation of printers using Internet Printing Protocol (IPP).
