KMS activation tool

The KMS activation tool is a system-level activation solution developed based on the Microsoft Key Management Service (KMS) mechanism. It simulates an enterprise-level batch authorization environment to achieve efficient activation of Windows operating systems and Office office suites. This tool adopts a modular architecture, supports UEFI and Legacy BIOS dual modes, is compatible with 32-bit/64-bit systems, and adapts to virtualization environments such as VMware and Hyper-V. It has become the tool of choice for technology enthusiasts and system administrators.

KMS activation tool function

Smart activation strategy:

Priority is given to digital license activation (such as Windows 10/11 permanent license), followed by KMS38 (valid until 2038), OEM (motherboard pre-activation) and traditional KMS (180-day cycle activation).

Automatically detect system version and hardware configuration, skip activated devices, and avoid repeated operations.

Multi-scenario support:

Supports the latest products such as Windows Server 2025 and Office 2024 preview, and is compatible with older systems such as Windows 7/8.1.

The retail version of Office can be converted into a volume-licensed version (R2V) to meet enterprise-level deployment needs.

Advanced management features:

Provides activation information backup/restoration, key management (installation/uninstallation/viewing), and system version switching (such as Windows 10 Home Edition to Professional Edition).

Support silent parameters (such as adding KMS38 protection to /lok) and adapt to unattended batch activation.

Technical compatibility:

Built-in KMS server simulator supports TCP/IP protocol and dynamic port allocation, and can penetrate firewalls and NAT networks.

Compatible with Windows 7 without relying on .NET Framework to avoid environment configuration conflicts.

KMS activation tool highlights

Activate technological innovation:

The original "KMS38 protection" mechanism extends the activation validity period to 2038 by modifying the system timestamp, breaking the traditional 180-day limit.

Supports Ohook method to intelligently and permanently activate Office without relying on external servers.

Safety protection system:

It adopts digital signature verification and built-in virus scanning module to ensure that the tool files are not tampered with.

The activation process does not write to the system's key registry, reducing the risk of blue screens.

Multilingual ecology:

Provides Simplified Chinese, Traditional Chinese, and English interfaces, and automatically identifies the system language.

Community support is active, and developers regularly update to adapt to Microsoft's anti-piracy policies.
