Microsoft released a non-security update on April 30 aimed at enhancing Windows stability and performance, particularly improving Windows Explorer functionality. The update improves the reliability of explorer.exe processes, enhances sign-in processes, interactions with taskbar menus, and unpinning items from Quick Access. It optimizes startup application performance and storage performance, raising the maximum FAT32 format size limit from 32GB to 2TB. Additional reliability improvements were made to Windows Hello, the Microsoft Store, and the taskbar system tray. The update also introduces Enterprise State Roaming (ESR) for device transitions, policy-based removal of preinstalled Microsoft applications, and enhanced security for batch files.

Microsoft has updated its Windows 11 operating system to enhance the management of preinstalled applications. The new RemoveDefaultMicrosoftStorePackages policy allows IT administrators to remove any preinstalled MSIX/APPX applications by referencing their Package Family Name (PFN) through Group Policy Object (GPO) or custom OMA-URI for mobile device management (MDM). This feature requires devices to have at least the April 2026 Windows non-security update. It is available for Windows 11 version 24H2 Enterprise and Education editions, whereas it was initially exclusive to version 25H2 or later. A comprehensive list of supported applications and instructions for applying the policy are provided in Microsoft's documentation. Additionally, a new policy setting enables the uninstallation of the AI-powered Copilot digital assistant from enterprise devices after the April 2026 Patch Tuesday updates. The dynamic list option for this policy will be rolled out in the coming months.

Microsoft has released the optional KB5083631 update for Windows 11 (Builds 26200.8328 and 26100.8328, version 24H2). Key features include a new Xbox Mode and an improved File Explorer experience, enhancing speed and stability. The update expands native file handling capabilities, allowing users to open and extract formats like .nupkg, .xar, .uu, and .cpio without third-party software. It integrates elements from Project K2 for optimization and improves the reliability of the explorer.exe process. Interface refinements include retaining the “Extra Large Icons” setting in the Downloads folder, fixing a “white flash” glitch in Dark Mode, and maintaining folder viewing preferences. The update package is about 5.1 GB for x64 systems and 4.6 GB for ARM architectures, with no major known issues reported. It can be accessed via Windows Update or offline installers, and these enhancements will be included in the mandatory May 2026 Patch Tuesday release.

Microsoft is implementing changes to the Windows Update process in Windows 11 to address user frustrations. Key updates include: 1. Users can delay updates indefinitely by selecting specific end dates for pauses, extending up to 35 days at a time. 2. The Power menu will now include options for "Update and shut down" and "Update and restart," giving users more control over when updates are finalized. 3. Microsoft is consolidating updates to reduce the number of restarts to one per month. 4. Users will no longer be forced to install updates during the setup of a new Windows PC, allowing updates to occur in the background. 5. Microsoft will provide more detailed information on updates, particularly for driver updates, by clarifying the device class in the titles. These changes are expected to be tested in the Windows Insider program before being released to the general public.

Windows 11 updates have significantly increased in size, with monthly cumulative updates often exceeding 4GB and some approaching 5GB. One update can expand to nearly 9GB when extracted. Microsoft has shifted to delivering Latest Cumulative Updates (LCUs), which include all previous fixes, leading to larger update sizes over time. The introduction of Checkpoint Cumulative Updates aims to reduce this growth by establishing periodic baselines, but the effectiveness has been mixed. The May 2025 cumulative update saw a size increase from approximately 6.5GB to nearly 9GB, with new MSIX files related to semantic search and on-device AI contributing to this growth. Windows Update uses applicability logic to minimize download sizes for users, but enterprises must download full packages, resulting in increased storage costs. The average yearly storage cost for enterprises rose from about 11 GB in 2024 to 52 GB by 2026. Users can check their actual download sizes through the Windows Update settings and Event Viewer logs.

Microsoft has introduced a new enterprise policy setting that allows IT administrators to silently uninstall the Microsoft Copilot app from managed Windows 11 devices. The RemoveMicrosoftCopilotApp policy became available after the April 2026 Patch Tuesday security updates and is compatible with enterprise management solutions like Microsoft Intune and System Center Configuration Manager (SCCM). Administrators can find the policy in the Group Policy Editor under User Configuration > Administrative Templates > Windows AI > Remove Microsoft Copilot App. It specifically targets Windows 11 Pro, Enterprise, and Education SKUs, excluding Home edition users. The uninstallation process is triggered when three conditions are met: Microsoft 365 Copilot is installed on the device, it was provisioned (not user-installed), and it has not been launched by the user in the last 28 days. The policy was initially available for Windows Insiders in January 2026 and became generally accessible afterward. However, future updates or user reinstalls from the Microsoft Store may reintroduce the Copilot app, necessitating ongoing policy enforcement for permanent removal. Organizations seeking broader exclusion may need to use PowerShell scripts or additional MDM configurations.

Microsoft has introduced a policy allowing IT administrators to remove the Microsoft Copilot app from managed enterprise devices. This "Remove Microsoft Copilot App" policy will be available as a Policy CSP and Group Policy after the April 2026 Windows security updates for Windows 11 devices on the 25H2 update, specifically for Enterprise, Professional, and Education editions. The policy will uninstall Copilot under certain conditions: both Microsoft 365 Copilot and Microsoft Copilot must be installed, the user must not have manually installed the app, and the app must not have been launched in the past 28 days. Administrators can enable the policy through the Group Policy Editor or configure it via Microsoft Intune and SCCM after the April 2026 updates. The policy aligns with Microsoft's recent changes in managing Copilot, including the cessation of automatic installations and the cancellation of plans to integrate Copilot into system notifications and other features. The policy was initially available to Windows Insiders in January before becoming generally accessible in April 2026.
