What is AmeThyst OS v.2?
AmeThyst OS v.2 is a modified (“lite”) version of Windows 11 Pro 24H2, build 26100.5074. Unlike the official Microsoft release, this build has been trimmed down to remove many features and apps considered unnecessary, with the goal of making the system lighter, faster, and more suitable for daily use on lower-end hardware.
- File size: ~2.8 GB (much smaller than the full Windows ISO)
- Default installation language: English
- Pre-activated (no license key required – which also raises concerns about legality)
- Intended for both virtual machines (VMs) and physical installations, though it is recommended to test in a VM first.
Key Features & Purpose
The purpose of AmeThyst OS v.2 is to deliver a lightweight Windows 11 experience. Some highlighted aspects include:
- Optimized performance – faster boot times, less resource consumption.
- Debloated system – most pre-installed Microsoft apps (“bloatware”) have been removed.
- Professional tools included – backup and restore utilities, disk management tools, file transfer solutions, and system utilities aimed at technicians.
- Daily usability – unlike some experimental lite builds, AmeThyst OS v.2 is meant to be stable enough for everyday tasks.
What Has Been Removed
One of the biggest differences compared to stock Windows 11 is the long list of removed or disabled features. These include:
- Microsoft bloatware apps
- Microsoft Edge
- Feedback Hub
- App-V (Application Virtualization)
- Assigned Access & Lockdown apps
- AutoPlay & Auto-Rotation Manager
- BranchCache Client
- Customer Experience Improvement Program (CEIP)
- Cross-Device Experience Host
- Cloud desktop features & notifications
- Device Experience, Device Update Center, Device Picker
- Data Center Bridging (DCB)
- Enterprise Data Protection
- Exchange ActiveSync support
- Face Recognition (Windows Hello Face)
- DVD Playback features
- DirectX WARP JIT
- Enhanced Storage
- Several accessibility and telemetry-related services
This removal makes the OS lighter but also means some Windows features, apps, and compatibility options will no longer be available.
New / Updated Features
Unlike official Microsoft releases, AmeThyst OS v.2 doesn’t really “add” new features — it mainly focuses on removing and optimizing. However, compared to the original Windows 11 Pro 24H2 build 26100.5074, here are some notable updates from Microsoft itself:
- Secure Boot certificate updates – Microsoft warns that the Secure Boot certificate will expire in June 2026, and updates are required to prevent boot issues.
- PowerShell 2.0 removed – starting with this build, PowerShell 2.0 is no longer included.
It’s unclear whether AmeThyst OS v.2 keeps these official changes, but since it’s based on the same build number, it’s likely included by default.
Risks & Considerations
Before using AmeThyst OS v.2, keep in mind:
- Not official – This is not supported by Microsoft. Updates may break or be blocked.
- Missing features – If you rely on certain apps (e.g., Microsoft Edge, Feedback Hub, or advanced security features), you may find them missing.
- Potential security risks – Pre-activated OS versions often use cracked methods that can compromise security.
- Legal issues – Since it bypasses licensing, it may not be legal to use in professional or enterprise environments.
Conclusion
AmeThyst OS v.2 is essentially a lightweight, stripped-down Windows 11 Pro (24H2) build aimed at users who want a fast, minimal system without the extra apps and features that come preloaded with Microsoft’s standard release.
It’s ideal for testing, VMs, or older hardware, but may not be suitable for professional or critical use due to missing features, potential update problems, and licensing concerns.
