winactivate is a script-based HWID (Hardware ID) and KMS38 activation tool. It's very easy to use - just run the script (winactivate.cmd) as administrator. Then your copy of Windows should be activated. It has been tested on Windows 10/11 Home, Professional and Enterprise Editions, as well as Windows 10 Enterprise 2016 LTSB and Windows 10 IoT.

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.

But there is just one drawback - it only supports for all editions/versions of Microsoft Windows (Server) & Office products with Volume License (i.e. the VOL edition).
