Windows IT Pro March 2026: Quality, Security, and AI Updates for Enterprise Admins

This month's Windows IT Pro update delivers substantial insights for enterprise administrators, covering everything from Windows quality improvements to new AI capabilities. Here's what IT professionals need to know about the latest developments shaping Windows management and security.

Windows Quality: Behind the Scenes

Windows + Devices EVP Pavan Davuluri has published a candid post titled "Our commitment to Windows quality," offering transparency into how Microsoft identifies issues, prioritizes fixes, and leverages the Windows Insider community to improve reliability before updates reach production environments. This behind-the-scenes look demonstrates Microsoft's renewed focus on quality as a competitive differentiator.

Autopatch Enhancements

Update Readiness Now Generally Available

Windows Autopatch's update readiness capability is now generally available, providing proactive detection and remediation of device update issues. This feature helps reduce downtime, improve update success rates, and lower security risks associated with outdated devices.

Hotpatch Updates Enabled by Default

Starting with the May 2026 security update, hotpatch updates will be enabled by default for all eligible devices in Microsoft Intune and those accessing the service via Microsoft Graph API. Organizations not ready for this change can access new controls to manage the transition.

Arm Support Expands

Remote Server Administration Tools (RSAT) are now officially supported on Arm-based Windows 11 PCs. This means administrators can remotely manage Windows server roles and features using Arm processors just as they would with traditional x64-based PCs, expanding deployment options for organizations investing in Arm architecture.

Secure Boot Certificate Updates

The March 2026 security update introduces two new PowerShell features for managing the ongoing Secure Boot certificate rollout:

• Get-SecureBootUEFI now supports the -Decoded option, displaying Secure Boot certificates in a readable format
• Get-SecureBootSVN allows checking the Secure Boot Security Version Number (SVN) of your device's UEFI firmware and bootloader

These tools help administrators verify whether devices follow the latest Secure Boot policy and report compliance status.

Universal Printing Revolution

Windows now ships with a single, universal inbox-class driver based on the industry standard IPP protocol and Mopria certification. This eliminates the need for device-specific drivers across traditional x64 PCs and the latest Copilot+ PCs running on Arm-based silicon. The experience remains consistent: plug in (or connect over the network) and print.

Windows 365 Expansion

Windows 365 Frontline in shared mode is now available in multiple new regions including Brazil South, Italy North, West Europe, New Zealand North, Mexico Central, Europe, Norway East, France Central, Spain Central, Germany West Central, and Switzerland North. Additionally, Windows 365 is now available for Government Community Cloud (GCC & GCC-High) organizations in the US Gov Texas region, with multi-region selection capabilities.

Remote Desktop Protocol Enhancements

Microsoft has released a sample repository demonstrating how to build RDP plugins using modern tools and development patterns. This resource helps developers extend RDP functionality while following current best practices.

Kernel Driver Security Hardening

Starting with the April 2026 security update, Microsoft will remove trust for all kernel drivers signed by the deprecated cross-signed root program. This change ensures that by default, only kernel drivers passed and signed by the Windows Hardware Compatibility Program (WHCP) can be loaded. This new kernel trust policy applies to devices running Windows 11 and Windows Server 2025.

Secure Boot Resources

Administrators can catch up on the latest Secure Boot FAQs by watching the March edition of "Secure Boot: Ask Microsoft Anything (AMA)" on demand. The next AMA is scheduled for April 23, 2026. New guidance resources include:

• Video deep dive: Secure Boot certificate updates explained
• Guide: Secure Boot troubleshooting
• Reference: A closer look at the high confidence database
• Documentation and sample PowerShell scripts: Sample Secure Boot E2E automation
• Guide: Secure Boot certificate update status in the Windows Security app

Native Sysmon Integration

System Monitor (Sysmon) functionality is now natively available in Windows. This allows capture of system events for threat detection, with custom configuration files to filter monitored events. Windows writes captured events to Windows Event Log, enabling security tools and other applications to utilize this data.

Windows Deployment Services Hardening

Following January 2026 announcements about CVE-2026-0386 vulnerabilities, the second phase of hardening changes for Windows Deployment Services (WDS) begins with the April 2026 security update. Hands-free deployment will be disabled by default to enforce secure behavior. Detailed guidance is available in the Windows Deployment Services (WDS) Hands-Free Deployment Hardening documentation.

AI Integration Developments

Windows 365 for Agents

Microsoft clarifies the distinction between Windows 365 for Agents and Microsoft Agent 365, explaining how these products work together to run agentic workloads securely, at scale, and under enterprise governance. This differentiation helps organizations understand the role of each product in their AI strategy.

Windows Server Updates

For the latest Windows Server features and improvements, administrators should consult the Windows Server 2025 release notes and Windows Server, version 23H2 release notes. The Windows Server Summit is scheduled for May 11-13, offering three days of practical, engineering-led guidance on real-world operations, security, and hybrid scenarios with live Q&A.

NVMe-over-Fabrics Support

A basic NVMe-over-Fabrics (NVMe-oF) initiator is available in the latest Windows Server Insiders build. This release introduces an in-box Windows initiator for NVMe/TCP and NVMe/RDMA, enabling early evaluation of networked NVMe storage using native Windows Server components.

Productivity and Collaboration Enhancements

Quick Machine Recovery

Quick Machine Recovery now turns on automatically for Windows Professional devices that are not domain-joined and not enrolled in enterprise endpoint management. These devices receive the same recovery features available to Windows Home users. For domain-joined or enterprise-managed devices, Quick Machine Recovery stays off unless explicitly enabled.

Built-in Network Speed Test

A built-in network speed test is now available from the taskbar, opening in the default browser to measure Ethernet, Wi-Fi, and cellular connections. This provides administrators with quick diagnostic capabilities without requiring third-party tools.

Camera Controls

Pan and tilt controls for supported cameras are now accessible in the Settings app, providing enhanced management capabilities for video conferencing and surveillance scenarios.

Enhanced Search Experience

Search on the taskbar now includes hover previews for search results and group headers that indicate when more results are available, improving the user experience for finding applications and files.

April 2026 Preview Features

The March 2026 optional non-security update for Windows 11, versions 25H2 and 24H2, includes gradual rollout of:

• Smart App Control: Can now be turned on or off without requiring a clean install
• Settings > About page: Features a more structured and intuitive experience with clearer device specifications and easier navigation to related components, including quick access to Storage settings

Lifecycle Management

Windows 10 Enterprise 2016 LTSB and Windows 10 IoT Enterprise 2016 LTSB will reach end of support on October 13, 2026. Windows Server 2016 will reach end of support on January 12, 2027. Organizations unable to migrate to newer releases can explore Extended Security Updates (ESU) for Windows 10 Enterprise 2016 LTSB to maintain monthly security updates.
