July 12, 2022—KB5015808 (OS Build 14393.5246)

Highlights

• Addresses a known issue that might prevent you from using the Wi-Fi hotspot feature.

• Addresses security issues for your Windows operating system.  

Improvements

This security update includes quality improvements. Key changes include:

• Addresses an issue that causes searchindexer.exe to stop responding during a dismount operation in the Remote Desktop setup environment.

• Addresses an issue that redirects the PowerShell command output so that transcript logs do not contain any content. Transcript logs might contain decrypted passwords if you turn PowerShell logging on. Consequently, the transcript logs lose the decrypted passwords.

• Addresses a known issue that might prevent you from using the Wi-Fi hotspot feature. When attempting to use the hotspot feature, the host device might lose the connection to the internet after a client device connects.

• Addresses an issue that prevents the use of Encrypted File System (EFS) files over a Web-based Distributed Authoring and Versioning (WebDAV) connection.

• Addresses an issue that causes Microsoft NTLM authentication using an external trust to fail. This issue occurs when a domain controller that contains the January 11, 2022 or later Windows update services the authentication request, is not in a root domain, and does not hold the Global Catalog role. The affected operations might log the following errors:

  • The security database has not been started.

  • The domain was in the wrong state to perform the security operation.

  • 0xc00000dd (STATUS_INVALID_DOMAIN_STATE).

• Addresses an issue that causes the primary domain controller (PDC) of the root domain to generate warning and error events in the System log. This issue occurs when the PDC incorrectly tries to scan outgoing-only trusts.

• Addresses an issue that might damage BitLocker virtual machine-based (VM) system files if you expand the BitLocker partition while the VM is offline.

• Addresses a known issue that prevents Windows servers that use the Routing and Remote Access Service (RRAS) from correctly directing internet traffic. Devices that connect to the server might not connect to the internet, and servers might lose connection to the internet after a client device connects to them.
