Because version 2.6.4 was designed for Windows 10 builds from 2016, it does not understand newer security features like Virtualization-Based Security (VBS) or the Pluton security chip on modern PCs. Forcing an old KMS emulator on a new Windows 10 22H2 system can cause:

While the phrase "Microsoft Toolkit 2.6.4 activate Windows 10" is searched thousands of times monthly, cybersecurity experts universally condemn its use. Here is why:

Large organizations use KMS (Key Management Service) to activate many computers on a local network without entering individual keys. The toolkit installs a fake KMS server on your own computer. It tells Windows, “Hey, I’m a legitimate corporate activation server,” and Windows activates for 180 days. The toolkit then schedules a background task to re-activate every 180 days automatically.

These files are almost never the genuine toolkit. They are often bundled with:
