Compared to the KMS activation method, permanent activation of Windows is becoming increasingly popular. Because that means as long as the core hardware of your computer remains the same, it will automatically activate even if the system is reinstalled. There are already many tools to permanently activate Windows 10 and Windows 11 using digital licenses, such as HWID GEN made by s1ave77, Microsoft Activation Scripts that integrates HWID/KMS38/Online KMS in one place, and CMWTAT Digital Edition that is powerful and easy-to-use.
CMWTAT Digital Edition (short for CloudMoe Windows 10+ Activation Toolkit Digital Edition, AKA: 云萌 Windows 10 数字权利激活工具) is a free and open-source permanent activation tool for Windows 10 and Windows 11 (x86, x64 and ARM64) using digital license, developed by TGSAN from China in 2017, using C#.
CMWTAT Digital Edition has both automatic and manual activation modes, supports activation of various editions of Windows 10/11, and allows seamless interconversion between multiple editions (product key installation only, no activation). It features not only the traditional 180-day KMS activation, but also the long-term Office-KMS activation, which can be maintained for up to 19 years even when the system is not connected to the Internet.
