    • “Code Integrity determined that a process (<process name>) attempted to load <binary name> that did not meet the Store signing level requirements.” 
  • The Company works upon a bug that leads some devices to have truncated names. This happens only when Autopilot provisioning assigns a name to them automatically.
  • They address an anomaly that depicts the wrong product description of Windows Server 2019 when enquired using slmgr/dlv. 
  • Earlier, Windows Management Instrumentation (WMI) class Win32_PhysicalMemory reports an error. This reads “32 GB memory chips have a missing Capacity value”. Microsoft has worked on this issue.
  • Windows 10 19H1 users can now easily copy or paste compound documents (previously OLE objects) between apps and host files. There is one necessity though, application, in concern, must support RichEdit control and other applications. 
  • Improves a bug that causes certain games leveraging Spatial Audio capabilities.

  • Addresses an issue that may prevent the personal identification number (PIN) prompt from appearing when authenticating in Internet Explorer. 

  • Resolves an issue with downloading digital rights management (DRM) files from certain websites using Microsoft Edge and Internet Explorer. 

  • Improves the user experience and app compatibility so that more Win32 apps will work with Windows Mixed Reality. 

  • Addresses an issue with LdapPermissiveModify requests, which fail to make Active Directory (AD) group membership changes if the Lightweight Directory Access Protocol (LDAP) client uses the Security Identifier (SID) syntax. In this scenario, Active Directory returns a “SUCCESS” status even though the change did not occur.

  • Works upon an issue that may prevent devices from starting when they start up using Preboot Execution Environment (PXE) images from Windows Deployment Services (WDS) or System Center Configuration Manager (SCCM). The error is, “Status: 0xc0000001, Info: A required device isn’t connected or can’t be accessed.”
