Windows Subsystem for Android explained: how it works, key features, limitations, and Microsoft’s official 2025 support ending—plus the best alternatives.
Windows Subsystem for Android (WSA) once promised a seamless way to run Android apps directly on Windows PCs, blurring the line between mobile and desktop computing. For developers, power users, and everyday Windows fans, it represented a major shift in how apps could be built, distributed, and used across platforms.
This in-depth guide explains what Windows Subsystem for Android is, how it works, its benefits and limitations, and—crucially—its current status and future, based on the latest official information available at the time of writing.
What Is Windows Subsystem for Android?
Windows Subsystem for Android is a Windows 11 feature introduced by Microsoft that allows Android apps to run natively on Windows without traditional emulators. It uses a virtualization-based approach, similar in concept to Windows Subsystem for Linux (WSL), to create a lightweight Android environment integrated directly into the Windows operating system.
Instead of emulating a full mobile device, WSA runs a modified Android Open Source Project (AOSP) environment that interacts closely with Windows. This enables Android apps to appear and behave like native Windows apps—complete with window resizing, taskbar integration, keyboard and mouse support, and system notifications.
Microsoft officially announced WSA alongside Windows 11 in 2021, positioning it as a major step toward cross-platform app compatibility.
How Windows Subsystem for Android Works Under the Hood
At a technical level, Windows Subsystem for Android relies on several core components working together:
Virtualization and Hyper-V
WSA runs Android inside a virtual machine powered by Hyper-V technology. This ensures:
- Strong isolation between Android and Windows processes
- Better security compared to traditional emulators
- Near-native performance on supported hardware
Android Runtime (AOSP-Based)
Rather than shipping Google Mobile Services (GMS), Microsoft used an AOSP-based Android runtime. This means:
- No native Google Play Store support
- Apps must rely on open Android APIs
- Some apps with deep Google dependencies may not work correctly
Integration With Windows 11
WSA was designed to feel “built-in,” not bolted on. Android apps could:
- Launch from the Start Menu
- Be pinned to the taskbar
- Receive Windows notifications
- Use keyboard, mouse, and touch input seamlessly
According to Microsoft’s official documentation, this tight integration was one of the project’s primary goals.
App Distribution: Amazon Appstore and Sideloading
Amazon Appstore on Windows
Instead of Google Play, Microsoft partnered with Amazon to bring Android apps to Windows via the Amazon Appstore. Users could browse, install, and update Android apps directly through the Microsoft Store.
You can still review Microsoft’s official explanation of this partnership on the Microsoft Learn platform, which remains a high-authority reference for Windows technologies.
Sideloading Android Apps
Advanced users and developers could sideload apps by installing APK files manually using Android Debug Bridge (ADB). This approach enabled:
- Testing apps not available on the Amazon Appstore
- Running internal or enterprise Android apps
- Experimentation with open-source Android tools
However, sideloading required enabling Developer Mode and basic command-line knowledge, making it less accessible for casual users.
Key Benefits of Windows Subsystem for Android
When fully supported, Windows Subsystem for Android offered several compelling advantages:
- No third-party emulators required, reducing security and performance risks
- Better performance than traditional Android emulators on supported PCs
- True desktop multitasking, including resizable windows
- Unified workflow for users who rely on both Android and Windows apps
For developers, it also opened doors for cross-platform testing without maintaining separate physical devices.
System Requirements and Compatibility
To run Windows Subsystem for Android, systems needed to meet specific criteria:
- Windows 11 (supported builds only)
- SSD storage
- At least 8 GB RAM (16 GB recommended)
- CPU with virtualization enabled in BIOS
- Hyper-V and Virtual Machine Platform features enabled
These requirements ensured smooth performance but also limited adoption on lower-end or older PCs.
Limitations and Common Issues
Despite its innovation, WSA had notable drawbacks:
No Google Play Services
Many popular apps depend heavily on Google APIs for:
- Maps
- Push notifications
- In-app purchases
Without Google Play Services, some apps failed to install or function properly.
App Availability Gaps
The Amazon Appstore catalog was significantly smaller than Google Play, especially outside the United States. This limited everyday usefulness for many users.
Resource Usage
Because WSA relied on virtualization, it could consume noticeable system resources, particularly on machines with 8 GB RAM or less.
The Big Update: Microsoft’s Official Deprecation of WSA
This is the most important development readers need to know.
In March 2024, Microsoft officially announced that Windows Subsystem for Android is being deprecated. According to Microsoft’s own support documentation and public statements:
- New installs are no longer supported for most users
- Amazon Appstore on Windows will stop being supported
- Full support ends in March 2025
After this date, WSA will no longer receive security updates, bug fixes, or feature improvements.
Microsoft has confirmed this decision on its official Windows support channels, citing shifting priorities and ecosystem challenges.
What Happens If You’re Still Using WSA?
If you already have Windows Subsystem for Android installed:
- Existing installations may continue working until support officially ends
- Security risks will increase after March 2025
- App compatibility may degrade over time
For long-term use, Microsoft strongly recommends transitioning away from WSA-based workflows.
Best Alternatives to Windows Subsystem for Android
With WSA being phased out, users and developers are exploring alternatives:
Android Emulators
Well-established emulators like BlueStacks and NoxPlayer continue to offer broad app compatibility, including Google Play support.
Native Web Apps and PWAs
Many popular Android apps now offer Progressive Web Apps (PWAs) that run smoothly in modern browsers on Windows.
Dual-Device Workflows
Microsoft increasingly promotes solutions like Phone Link, which mirrors Android apps and notifications directly from your phone to your PC without running Android locally.

Who Should Care About Windows Subsystem for Android Today?
Windows Subsystem for Android still matters conceptually, even as it sunsets:
- Developers can learn from its architecture and integration model
- Product managers and IT teams can study it as a case example of cross-platform strategy
- Power users can decide when and how to migrate
Understanding why WSA struggled also provides insight into the broader challenges of unifying mobile and desktop ecosystems.
Practical Takeaways Before Support Ends
If you’re currently relying on WSA:
- Begin planning a migration now
- Avoid using it for sensitive or mission-critical tasks
- Export or back up any important app data
- Test alternative tools early to reduce downtime
Action step: Review your most-used Android apps on Windows and identify whether an emulator, PWA, or Phone Link can replace each one effectively.
The Future of Android Apps on Windows
While Windows Subsystem for Android is ending, Microsoft hasn’t abandoned cross-device experiences. Instead, the company appears focused on:
- Cloud-based app access
- Deeper phone–PC integration
- Web-first application models
This shift reflects broader industry trends favoring flexibility, security, and reduced platform fragmentation.
Final Thoughts: Is Windows Subsystem for Android Still Worth Learning About?
Windows Subsystem for Android represents an ambitious chapter in Windows history—one that pushed boundaries but ultimately faced ecosystem and adoption challenges. While it’s no longer a long-term solution, understanding how it worked helps users and professionals make better decisions about the future of app compatibility on Windows.
