Beware of this.
Key Details on the Deprecation
- Target: This method was specifically for "activating" Windows 10/11 and Windows Server until the year 2038. It was not the primary method used for Microsoft Office activation.
- The Change: Microsoft fully deprecated the clip-based KMS license migration functionality that the KMS38 method relied on.
- Affects All Versions? No. It affects newer versions of Windows that have received the critical update.
KMS38 stopped working beginning with Windows build 26100.7019 (released around November 2025).
It is now removed from the latest versions of the Massgrave script.
- Current Alternatives: The Massgrave developer advises users to switch to the HWID (Hardware ID) or TSforge activation methods, which are reported to still function.

Do you actually have to use their downloader link, or can you simply use their key for activation?
