What Is Windows 11 Version 26H1?

Windows 11 Version 26H1 is a specialized Windows release created to support hardware innovations introduced during 2026. Microsoft states that the version is available only on new devices using selected new silicon.

Computers running earlier Windows 11 releases are not expected to receive Version 26H1 through Windows Update. Microsoft also states that it cannot be installed as a normal in-place upgrade on existing devices.

This makes Version 26H1 different from versions such as Windows 11 24H2 and 25H2, which were released to a broader range of compatible computers.

What Is New in Build 28000.2525?

Build 28000.2525 is a cumulative update rather than an entirely new operating system release. It combines the latest security corrections with improvements previously introduced through optional preview updates.

Microsoft describes KB5101649 as containing the latest security fixes and improvements alongside non-security updates from the previous month’s optional preview release.

The update focuses on several important areas:

Windows security and vulnerability protection
System reliability and stability
Recovery and troubleshooting tools
Artificial intelligence hardware monitoring
Camera and multimedia functionality
Windows installation improvements
Compatibility with new-generation processors
Performance and power management
Previous cumulative fixes

Because the package is cumulative, users do not need to install every older update separately before installing KB5101649.

Point-in-Time Restore

One of the important improvements associated with the July update is expanded support for Point-in-Time Restore.

This recovery feature is designed to help users return Windows to an earlier working state when a system update, driver, configuration change, or application causes serious problems.

Compared with traditional recovery methods, Point-in-Time Restore aims to provide a more complete recovery experience by restoring important system files, settings, applications, and user data to a previous state.

The feature can be particularly valuable after:

A failed Windows update
An incompatible hardware driver
Software installation problems
Damaged system settings
Unexpected application conflicts
Serious performance or stability issues

Feature availability may depend on the device model, Windows configuration, and Microsoft’s gradual rollout process.

NPU Usage in Task Manager

Windows 11 26H1 provides improved support for computers equipped with a neural processing unit, commonly known as an NPU.

An NPU is a specialized processor designed to accelerate artificial intelligence workloads without placing the entire load on the main processor or graphics card.

Build 28000.2525 can provide additional NPU usage information through Task Manager on supported devices. This allows users to monitor how applications and Windows features use dedicated artificial intelligence hardware.

The information can help users understand:

Which programs are using the NPU
How heavily the neural processor is being used
Whether AI workloads are running locally
How system resources are distributed
Whether supported AI applications are working correctly

This feature is mainly useful on Copilot+ PCs and other compatible systems with integrated AI acceleration.

Multi-Application Camera Support

The update also improves camera functionality by supporting scenarios in which multiple applications need to access the same camera.

Traditionally, Windows applications may prevent another program from using the camera while it is already active. Improved multi-application camera support can make it easier to use accessibility software, streaming tools, communication applications, and camera utilities simultaneously.

For example, a user may be able to operate a video-conferencing application while also using accessibility or recording software that needs access to the camera feed.

Actual support may depend on the camera driver, device manufacturer, application, and Windows configuration.

Custom User Folder Name During Setup

Windows 11 normally creates the local user-profile folder automatically during the initial setup process. In some cases, the resulting folder name may be shortened or generated from part of the user’s Microsoft account address.

The updated setup experience can provide users with greater control over the name assigned to their user folder during device configuration.

This is useful for users who prefer a cleaner folder path, such as:

C:\Users\John

instead of an automatically shortened or less recognizable folder name.

The improvement can also help developers, administrators, and advanced users who rely on predictable file paths.

Security Improvements

KB5101649 is part of Microsoft’s July 2026 security update cycle. Its main purpose is to address security weaknesses and improve protection across important Windows components.

Security improvements may affect areas such as:

The Windows kernel
Authentication and account security
Network communication
System services
Driver handling
Application permissions
File and storage operations
Microsoft Edge components
Windows recovery features
Virtualization and security isolation

Security analysis for the update indicates that Windows 11 Version 26H1 systems running builds earlier than 28000.2525 may be affected by multiple vulnerabilities corrected by the update.

Installing current security updates is strongly recommended for devices used for work, online banking, personal documents, or sensitive information.

Performance and Reliability
