Features Removed in Windows 11 25H2: What You Need to Know

Introduction

Microsoft has made significant changes to features removed in Windows 11 25H2, focusing on modernizing the operating system by eliminating legacy components that pose security risks and maintenance challenges. Windows 11, version 25H2 also includes some feature removals such as PowerShell 2.0 and Windows Management Instrumentation command-line (WMIC), marking a decisive shift toward modern administrative tools.

Understanding these Windows 11 25H2 deprecated features is crucial for IT professionals, system administrators, and power users who rely on legacy tools for system management and automation. This comprehensive guide explores what’s being removed, why Microsoft made these decisions, and how to prepare for a smooth transition to modern alternatives.

Overview of Removed Features in Windows 11 25H2

Primary Components Being Eliminated

Microsoft’s strategy with Windows 11 25H2 focuses on removing legacy administrative tools that have been deprecated for years. The explicit removal of PowerShell 2.0 and the deprecation of WMIC represent necessary housekeeping that improves security posture but imposes a clear operational cost in the form of migration work for legacy scripts and tooling.

Main Features Removed:

• PowerShell 2.0 Engine: Complete removal from shipping images
• Windows Management Instrumentation Command-line (WMIC): Tool elimination after upgrade
• Legacy Scripting Components: Deprecated automation interfaces
• Outdated System Management Tools: Various legacy administrative utilities

Timeline and Implementation

The removal begins for Windows 11, version 24H2 (rolling into later builds) starting August 2025, and for Windows Server 2025 in September 2025. Windows Insider preview builds already reflect these changes, allowing IT professionals to test and prepare migration strategies.

Key Timeline Milestones:

• July 2025: Insider preview builds show PowerShell 2.0 feature removed
• August 2025: PowerShell 2.0 removal begins for Windows 11 24H2+
• September 2025: Windows Server 2025 affected by removals
• October 2025: Expected general availability with all removals

PowerShell 2.0: End of an Era

What PowerShell 2.0 Was and Its Legacy

PowerShell 2.0 will be removed in a later release starting in August 2025 for Windows 11, version 24H2 and a September 2025 release for Windows Server 2025. Microsoft formally deprecated PowerShell 2.0 years ago and left it in images as an optional compatibility feature to avoid breaking legacy scripts and installers.

PowerShell 2.0 Historical Context:

• Release Date: Originally shipped with Windows 7 and Windows Server 2008 R2
• Purpose: Early automation and scripting capabilities for Windows
• Limitations: Limited functionality compared to modern PowerShell versions
• Security Concerns: Lacks modern security features and protections

Why Microsoft Is Removing PowerShell 2.0

Security and Modernization Reasons:

• Security Vulnerabilities: Legacy engine lacks current security protections
• Maintenance Overhead: Resources better allocated to modern PowerShell development
• Attack Surface Reduction: Eliminating potential exploitation vectors
• User Experience: Encouraging adoption of superior modern alternatives

Impact on Existing Systems

Affected Scenarios:

• Legacy Automation Scripts: Older scripts specifically targeting PowerShell 2.0
• Third-Party Software: Applications that explicitly require PowerShell 2.0
• Enterprise Workflows: Established business processes using legacy scripting
• Installation Packages: Software installers dependent on PowerShell 2.0

Key Takeaway Box:

PowerShell 2.0 removal affects primarily legacy scripts and software installers. Most modern applications and administrative tasks already use current PowerShell versions and won’t be impacted by this change.

WMIC Removal: Transitioning from Legacy Management

Understanding WMIC and Its Role

Windows Management Instrumentation Command-line (WMIC) tool will be removed after upgrading to Windows 11 25H2 and later. WMIC is a legacy built-in Windows command-line tool that allows users to interact with the Windows Management Instrumentation (WMI) system for system management and administrative tasks.

WMIC Capabilities:

• System Information: Hardware and software inventory queries
• Process Management: Starting, stopping, and monitoring processes
• Service Control: Managing Windows services and configurations
• Network Management: Network adapter and connectivity administration

Microsoft’s Rationale for WMIC Deprecation

Technical and Strategic Reasons:

• Modern Alternatives Available: PowerShell provides superior WMI access
• Limited Functionality: WMIC lacks advanced features of modern tools
• Maintenance Cost: Resources better invested in PowerShell ecosystem
• Consistency: Standardizing on PowerShell for all administrative tasks

WMIC Replacement Strategies

WMIC will be removed after an upgrade to Windows 11, version 25H2 and later. You should update your scripts and tools to use PowerShell or another supported method as soon as possible. Anything you did with a WMIC command can be run with PowerShell.

PowerShell Alternatives:

• Get-WmiObject: Direct WMI object access
• Get-CimInstance: Modern CIM/WMI cmdlets
• Invoke-CimMethod: Method execution capabilities
• Custom Functions: Tailored PowerShell functions for specific needs

Migration Planning and Preparation

Assessment Phase: Identifying Dependencies

Inventory and Analysis Steps:

1. Script Auditing: Catalog all PowerShell 2.0 and WMIC usage
2. Application Review: Identify software dependent on deprecated features
3. Workflow Mapping: Document business processes using legacy tools
4. Priority Assessment: Classify critical vs. non-critical dependencies

PowerShell 2.0 Migration Strategies

Modernization Approaches:

• Script Updates: Convert PowerShell 2.0 scripts to current versions
• Function Libraries: Create modern PowerShell modules for common tasks
• Testing Protocols: Validate converted scripts in test environments
• Documentation: Update procedures and training materials

WMIC to PowerShell Conversion

Common WMIC Commands and PowerShell Equivalents:

System Information:

• WMIC: wmic computersystem get model,name,manufacturer
• PowerShell: Get-CimInstance -ClassName Win32_ComputerSystem

Process Management:

• WMIC: wmic process get name,processid
• PowerShell: Get-Process | Select-Object Name, Id

Service Control:

• WMIC: wmic service get name,state
• PowerShell: Get-Service | Select-Object Name, Status

Real-World Impact and Use Cases

Enterprise Environment Considerations

Large Organization Challenges:

• Script Inventory: Thousands of automation scripts requiring review
• Application Dependencies: Third-party software with PowerShell 2.0 requirements
• Training Requirements: IT staff education on modern PowerShell features
