Microsoft's Trusted Platform Module, specifically TPM 2.0, has been part of Windows 11's system requirements since the operating system's introduction in 2021. Now that the TPM is ubiquitous, being included with most CPUs for many years, Microsoft is looking to leverage it "to activate Windows devices at scale."
Currently, the enterprise sector activates Windows via Microsoft's Key Management Service (KMS), but according to the Windows IT Pro Blog, "modern organizations increasingly require stronger assurances around device identity and activation integrity." Basically, hackers can already clone or fake KMS server software, so the TPM is intended to provide a hardware-level security check to curb this.
