Microsoft will begin rolling out the May 2026 Security Update for Windows 11 on May 12, 2026. Key features of this update include: 1. Xbox Mode: Transforms PCs into a console-like experience, prioritizing system resources for gaming and freeing up to 2GB of memory. 2. Voice Typing Improvements: Redesign of Voice Typing elements on the touch keyboard. 3. New Arabic 101 Legacy Keyboard Layout: Available for addition from the Region page in Settings. 4. Drop Tray Changes: Renamed from Drag Tray and can be disabled in Settings > System > Multitasking. 5.

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.

The FAT32 file system, historically limited to a 32GB partition size due to a design choice by Microsoft engineer Dave Plummer, can inherently support volumes up to 2TB with a 512-byte sector size and theoretically up to 16TB with 4KB sectors. While Windows maintained this 32GB limit, motherboard manufacturers had already developed firmware to utilize larger FAT32 drives. Tools like Rufus and GUIFormat were used to format high-capacity media, as Windows did not allow direct FAT32 formatting for drives larger than 32GB. However, with the introduction of Windows 11 Insider Preview Builds 26220.8165 and 26300.8170, users can now format large flash drives and external volumes as FAT32 directly from the Command Prompt without third-party software.

Microsoft has lifted the FAT32 file system's volume limit in a recent preview version of Windows 11, allowing users to format storage devices with capacities of up to 2 terabytes, an increase from the previous maximum of 32 gigabytes. This change addresses a long-standing limitation that has existed since 1996. Additionally, Microsoft is enhancing the partition tool in Windows 11, improving its speed and responsiveness for managing multiple partitions. These updates are currently being tested in the Windows Insider Program, with no confirmed timeline for broader availability.

Microsoft has released new test builds for Windows Insiders, specifically Dev Build 26300.8170 and Beta Build 26220.8165, which remove the 32GB limit on FAT32 formatting for external drives. Users can now format external drives up to 2TB using FAT32 through the Command Prompt. This change, which has been anticipated by users, is a shift from the long-standing restriction that required third-party applications or specialized commands for larger drives. The enhancement applies only to the Command Prompt, as the graphical interface remains unchanged, and the 4GB file size limit for individual files on FAT32 drives still applies. This feature is currently available only in preview versions for Windows Insiders, with a broader rollout planned for future standard Windows 11 updates.
