Microsoft has temporarily suspended the automatic installation of the Microsoft 365 Copilot app on Windows PCs equipped with M365 applications due to user resistance. The rollout, which began in December, was intended to integrate AI functionalities across tools like Word, Excel, and PowerPoint. Users in the European Economic Area were excluded by default, and IT administrators had the option to opt out. Existing installations of the app will not be removed, and users can choose to uninstall it if desired. Microsoft plans to provide further updates before any future rollout.

Microsoft's Hyper-V is a hardware virtualization platform integrated into Windows 11 Professional, Enterprise, and Education editions, allowing users to host multiple virtual machines (VMs) on a single computer. It operates using a type 1 hypervisor directly on hardware, enabling VMs to share resources like CPU, memory, and storage. Hyper-V includes features such as dynamic memory allocation, software-defined networking, and saved checkpoints. IT administrators may need to disable Hyper-V due to compatibility issues with third-party virtualization software, high-precision applications, or driver conflicts. Disabling Hyper-V can also affect security features reliant on it, such as virtualization-based security (VBS) and Device Guard. Methods to disable Hyper-V include: 1. Using the Windows Features dialog. 2. Executing a PowerShell command: Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All, HypervisorPlatform, VirtualMachinePlatform. 3. Running a DISM command: dism /Online /Disable-Feature /FeatureName:Microsoft-Hyper-V-All /FeatureName:HypervisorPlatform /FeatureName:VirtualMachinePlatform. 4. Using the bcdedit command: bcdedit /set hypervisorlaunchtype off. 5. Modifying Group Policy to disable VBS. 6. Editing the Windows Registry to disable VBS or Credential Guard. For multiple managed computers, administrators can create and execute a PowerShell script or use Group Policy Objects to streamline the process. Testing in a controlled environment is recommended to ensure desired outcomes without compromising security or functionality.

Windows 11 Pro includes features such as BitLocker, Smart App Control, Dynamic Lock, Controlled Folder Access, Windows Sandbox, Hyper-V, Group Policy, Assigned Access, and Remote Desktop, which enhance security and management for users, especially in hybrid work environments. - BitLocker encrypts drives to protect files if a device is lost or storage is removed. - Smart App Control blocks untrusted or unsigned applications before they run. - Dynamic Lock automatically locks the device when a paired phone moves out of range. - Controlled Folder Access protects files in designated folders from unauthorized modifications. - Windows Sandbox provides a temporary, isolated environment for testing software without affecting the main system. - Hyper-V allows users to run virtual machines and test different operating systems. - Group Policy Editor offers advanced settings for managing updates and security protocols. - Assigned Access restricts a device to a single application for shared-use scenarios. - Remote Desktop enables users to access their main PC remotely from other devices. Recommended features to enable for enhanced security and workflow include BitLocker, Controlled Folder Access, Dynamic Lock, and Remote Desktop. Windows Sandbox is suggested for users dealing with unknown files, while Hyper-V is for advanced users. Group Policy and Assigned Access are beneficial for specific management needs.

Microsoft will enable hotpatch security updates by default for eligible Windows devices managed through Microsoft Intune and the Microsoft Graph API starting with the May 2026 Windows security update. This change aims to enhance security and reduce the time to achieve 90% patch compliance by half. The updates will be managed through Windows Autopatch, which allows organizations to apply updates without manual intervention. Administrators can manage hotpatch updates at the tenant level and can opt-out starting April 1, 2026. A Hotpatch quality updates report will be available in Intune to ensure devices are ready for the updates. Windows Autopatch became generally available in July 2022 and is currently operational on over 10 million production devices.

Microsoft will automatically enable hotpatch security updates for Windows devices managed through Microsoft Intune or the Microsoft Graph API starting with the May 2026 Windows security update. This feature allows security fixes to be applied without requiring a device restart, improving compliance efficiency. Devices that install the April 2026 baseline security update will begin receiving hotpatch updates in May 2026, but this will only apply to devices not already assigned to a quality update policy. Organizations can opt out of hotpatch updates for specific device groups or their entire tenant starting April 1, 2026.

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.
