Overview

Windows 11 25H2, also known as the Windows 11 2025 Update, is the next major feature update for Microsoft's operating system. Expected to be released in October 2025, this update is unique because it shares the same core as Windows 11 24H2. Instead of a full upgrade, 25H2 is delivered as an enablement package that quickly activates new features already present but dormant in 24H2. This approach ensures a faster and smoother installation process for users already on the latest version.

Key Highlights

  • Release Date: Expected October 2025
  • Update Type: Enablement package for 24H2 users; full feature update for older versions
  • Installation Size: Very small (under 5MB) for 24H2 users; larger for others
  • Support Lifecycle: 24 months for Home/Pro; 36 months for Enterprise/Education
  • Free Upgrade: Yes, for all compatible Windows 11 and Windows 10 devices

New Features and Improvements

1. Start Menu Redesign

  • Wider Layout: Accommodates up to eight pins per row and up to three rows of suggested files/apps.
  • Customizable Pins: Option to show all pins by default or keep the compact two-row view.
  • Hide Recommended Section: Users can completely hide the Recommended section for a cleaner interface.
  • New "All" Section: Access all installed apps directly from the Start menu without opening a separate page. Supports grid, list, and category views.
  • Updated Settings Page: Simplified Start settings with options to control pins and recommendations.

2. Start Menu Sidebar Redesign

  • Improved integration with mobile devices, allowing users to scroll through more activities.
  • Direct access to messages, calls, photos, and app updates from linked iPhone or Android devices.

3. Taskbar: Resume Android Apps

  • Users can start an app on their Android phone and receive a "Resume alert" on the Windows Taskbar.
  • Clicking the alert opens the corresponding app (if installed) or prompts installation from the Microsoft Store.
  • Requires enabling "Allow this PC to access your mobile devices" under Bluetooth & devices settings.

4. Click to Do Enhancements (Copilot+ PCs)

  • Describe Image: AI-powered feature to generate descriptions of images, charts, and graphs.
  • Interactive Tutorial: Step-by-step guide for new users to understand Click to Do functionality.
  • New Selection Modes:
    • Freeform Selection: Draw around items with finger or pen.
    • Rectangle Selection: Create a rectangular selection area.
    • Ctrl + Click: Select multiple items across different types.
  • Touch Gestures: Press and hold with two fingers to activate Click to Do on touch-enabled devices.

How to Upgrade

From Windows 11 24H2

  • The upgrade is delivered via a small enablement package (.ekb).
  • Go to Settings > Windows Update > Check for updates.
  • Click "Download and install" when the 25H2 update appears.
  • The process requires only one restart and takes minutes.

From Windows 11 23H2 or Older, or Windows 10

  • A full feature update is required.
  • Use Windows Update, Installation Assistant, or ISO media for a clean install or in-place upgrade.
  • Check compatibility with the PC Health Check app before upgrading.

Early Access via Windows Insider Program

  • Enroll in the Release Preview, Dev, or Beta Channels to receive 25H2 ahead of public release.

Important Notes

  • Feature Availability: Some features may roll out gradually after release. Not all features will be available on every device—certain enhancements require Copilot+ PC hardware.
  • No Forced Upgrade: Microsoft will not automatically force the update initially. Users can choose when to upgrade.
  • Compatibility: Since 25H2 shares the same core as 24H2, application and driver compatibility should remain consistent.
  • PowerShell 2.0 Deprecated: PowerShell 2.0 is no longer included. Users should migrate to PowerShell 5.1 or newer.

System Requirements

Windows 11 25H2 has the same system requirements as Windows 11 24H2. Ensure your device meets the following minimum criteria:

  • Processor: 1 gigahertz (GHz) or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC)
  • RAM: 4 gigabytes (GB) or greater
  • Storage: 64 GB or greater available disk space
  • System Firmware: UEFI, Secure Boot capable
  • TPM: Version 2.0
  • Graphics Card: Compatible with DirectX 12 or later with WDDM 2.0 driver
  • Display: High definition (720p) display, greater than 9” diagonally, 8 bits per color channel

Known Issues

As of the latest previews, no widespread critical issues have been reported. Microsoft will document any known issues on the official Windows Release Health dashboard as the update approaches general availability.

Conclusion

Windows 11 25H2 is a lightweight but significant update that refines the user experience with a redesigned Start menu, deeper mobile integration, and AI-powered features for Copilot+ PCs. Its enablement package delivery model ensures minimal disruption for current 24H2 users, while those on older versions will still benefit from a full feature update. With extended support and no forced upgrades, 25H2 represents a user-friendly approach to annual Windows updates. Stay tuned for the official release in October 2025.
