July 2026 Patch Tuesday: KB5101650 Windows 11 Update

On July 14, 2026, Microsoft released cumulative update KB5101650 for Windows 11 versions 25H2 and 24H2, addressing OS Builds 26200.8875 and 26100.8875. This update includes essential security fixes, updates to Secure Boot certificates, and enhanced Remote Desktop Protocol (RDP) defenses against phishing attacks. It consolidates July 2026's security content, addressing known vulnerabilities and introducing functional improvements. The update is critical for minimizing exposure to identified threats and is prioritized for systems managing remote access or nearing certificate expiration. The update enhances Remote Desktop security by supporting SHA-2 certificate thumbprints while retaining SHA-1 for legacy compatibility. It includes new Group Policy options to mitigate phishing risks associated with malicious .rdp files. The curl upgrade to version 8.21.0 incorporates security patches for command-line tools in Windows environments. Secure Boot certificates are automatically updated through Windows updates, ensuring boot security across various hardware. KB5101650 installs primarily through the Windows Update interface, requiring a restart to activate changes. Enterprise environments can use the Microsoft Update Catalog for manual distribution. A temporary restriction affects certain Dell devices with Intel Innovation Platform Framework drivers, which Microsoft plans to address in a future update. The cumulative update resolves a total of 622 Microsoft CVEs, including 416 affecting Windows components. Users are advised to verify and install the update promptly to secure the full suite of improvements.

Microsoft’s Secure Boot certificates expire in June 2026, but older PCs may never get the fix

Every Secure Boot-enabled Windows PC relies on cryptographic certificates issued by Microsoft in 2011, embedded in the motherboard's firmware, to ensure a secure boot process. The first of these certificates will expire on June 24, 2026, which will affect the ability to receive future security updates for critical components of the Windows startup process. Microsoft is rolling out replacement certificates through Windows Update, marking a significant security maintenance effort. Secure Boot operates as a chain of trust with certificates stored in the motherboard's UEFI firmware, validating software before the operating system loads. The Platform Key (PK) is at the top of this chain, followed by the Key Exchange Key (KEK) and the Signature Database (DB). The replacement certificates introduced in 2023 restructure certificate management, separating responsibilities among different certificate authorities to enhance the trust model. Not all PCs are affected by the upcoming expiration; newer devices manufactured since 2024 already have the new certificates. Windows 10 users face challenges as support for this version ends in October 2025, and they will not receive the new certificates unless enrolled in Extended Security Updates. Home users should ensure their PCs are set to receive updates automatically, while enterprise environments require coordination for firmware updates before the Windows certificate update.

How Pixel and Android are bringing a new level of trust to your images with C2PA Content Credentials

The Google Pixel 10 phones incorporate C2PA Content Credentials in their camera and Google Photos, marking them as the first to attach these credentials to every photograph taken. The Pixel Camera app has achieved Assurance Level 2, the highest security rating from the C2PA Conformance Program, ensuring a secure environment for digital content. The integration employs a private-by-design strategy for certificate management, preventing traceability back to the creator. On-device trusted time-stamps allow users to trust images even after the certificate expires. The technology is supported by the Google Tensor G5 and Titan M2 security chip, enhancing hardware-backed security features. Content Credentials provide detailed information about the creation and protection of media files, helping users identify AI-generated or altered content. Google is a steering committee member of the Coalition for Content Provenance and Authenticity (C2PA), which aims to establish industry standards for digital content verification. The Pixel 10 categorizes digital content based on verifiable proof of its creation process. Each JPEG photo captured includes Content Credentials, and Google Photos validates these credentials for edited images. The implementation architecture is designed to be secure, verifiable, and usable offline. Google employs a unique certificate management strategy to enhance user privacy, ensuring that each key and certificate is used for only one image. An on-device offline time-stamping authority allows for the generation of trusted time-stamps without requiring internet connectivity.

New Windows Feature Limits Admin Privileges

Microsoft has introduced a security feature called Administrator Protection in its latest Windows preview version, aimed at enhancing local administrator privileges and reducing the risk of privilege escalation exploits. This feature changes the elevation of privileges from an unrestricted process to a controlled "just-in-time" event, utilizing an isolated, ephemeral shadow administrator account that disappears after use. This approach replaces the previous split-token model governed by User Account Control (UAC) and complicates attempts by cybercriminals to misuse elevated privileges. The feature is designed to hinder attackers who exploit common applications and administrative privileges for lateral movement within networks. It is disabled by default and requires activation via group policy. Additionally, it improves monitoring capabilities for organizations by allowing better oversight of short-lived privileged accounts.

Automating Certificate Lifecycle Management in Windows OS with AppViewX AVX ONE CLM

Automating certificate lifecycle management (CLM) in Windows operating systems involves challenges due to the complexity of various certificate stores and the need to manage system-level and user-level certificates. Privilege management is also a significant hurdle, as it requires balancing least privilege with the need for elevated permissions. The AppViewX AVX ONE CLM platform, particularly the AppViewX Windows Gateway component, addresses these challenges by automating CLM actions such as deployment, renewal, and revocation of certificates, while facilitating script execution for Windows system configuration. The AppViewX Windows Gateway uses three communication modes to interact with certificate authorities (CAs): WMI, Native API, and PowerShell. - WMI: Utilizes standard remote WMI queries via RPC, requiring TCP port 135 for initial connection and dynamic ports ranging from 49152 to 65535 for subsequent communications. Proper firewall configurations must allow inbound traffic on ports 135 and the dynamic RPC ports. - PowerShell: Requires PowerShell remoting to be enabled using the Enable-PSRemoting command, utilizing port 5985 for WinRM. - Native API: Interacts directly with the OS kernel and hardware for high-performance capabilities, specifically for Microsoft CA communication, using port 135 for RPC-based protocol messages. The AppViewX Windows Gateway simplifies the tasks of PKI administrators managing certificate lifecycles in Windows environments. An Implementation Architect from AppViewX is available to assist with the installation prerequisites for the AppViewX Windows Gateway.
