On July 22, Microsoft unveiled its latest initiative, the KMS Hardware-Secured requirement, which ties Windows volume activation servers to a TPM chip. This announcement has sparked discussions among users, particularly regarding its implications for pirated versions of Windows 11. While some tech outlets have suggested that this move signifies a crackdown on piracy, the reality is more nuanced.
Microsoft’s focus with this new requirement is primarily on organizations that operate their own Key Management Service (KMS) servers. KMS is a volume licensing tool that allows companies to activate multiple Windows PCs from a single internal server, streamlining the activation process. The new rule aims to enhance security by ensuring that KMS hosts must prove their identity and integrity through the TPM before being allowed to activate any Windows machines.
Why is Microsoft doing this?
The motivation behind this initiative stems from concerns over unauthorized activation methods. Attackers have previously exploited fake or cloned KMS servers to activate unlicensed Windows machines within organizations. By implementing KMS Hardware-Secured, Microsoft aims to bolster defenses against such fraudulent activities. The TPM will verify two critical aspects:
- The hardware identity of the KMS host.
- The integrity of the platform, ensuring it has not been tampered with since its identity was established.
If a KMS host fails either of these checks, it will be barred from issuing licenses.
How organizations should prepare, according to Microsoft
For organizations with physical KMS hosts, Microsoft recommends verifying that the host is certified on the Windows Server Catalog and that its TPM is both installed and enabled. Guidance for virtual KMS hosts is forthcoming, indicating that Microsoft is still finalizing the requirements for this scenario. However, there is no immediate cause for concern. Administrators can assess TPM readiness by executing a simple command in PowerShell:
Get-TpmSupportedFeature -FeatureList “Key Attestation”
A response indicating “key attestation” confirms that the necessary capability exists prior to the enforcement of KMS Hardware-Secured.
Microsoft isn’t cracking down on pirated Windows for regular users
Contrary to some reports, KMS Hardware-Secured does not target individual users with pirated copies of Windows. The checks implemented are specific to the KMS servers used by organizations, not the personal devices of everyday users. The confusion may have arisen from discussions surrounding KMS38, a piracy method that Microsoft disabled in November 2025. However, KMS38 was unrelated to TPM chips or KMS servers and exploited a different activation method entirely.
Most pirated Windows installs today don’t use KMS at all
Many current piracy methods, such as HWID activation, do not involve KMS servers. Instead, they register a PC’s hardware ID directly with Microsoft’s activation servers, creating a permanent digital license without the need for a KMS host. This means that the new KMS Hardware-Secured measures will not impact the majority of existing piracy methods.
Why Windows piracy is still so widespread
While Microsoft demonstrates its capability to implement robust anti-piracy measures, the company appears less concerned with individual instances of piracy than with maintaining user engagement with its ecosystem. The cost of a Windows 11 Home license, priced at 9, can be a significant barrier for budget-conscious consumers, contributing to the continued prevalence of piracy tools like Massgrave.
Interestingly, Microsoft has not pursued legal action against home users for minor instances of piracy, as the costs of such actions would outweigh potential recoveries. Instead, the company’s revenue strategy increasingly relies on subscriptions and services, such as Microsoft 365 and OneDrive, rather than solely on Windows license sales. This shift in focus has led to a user experience filled with upsells, prompting Microsoft to acknowledge the need for a more user-friendly approach.
Ultimately, while KMS Hardware-Secured represents a step towards enhanced security for organizational environments, it does not signify a war on individual users with pirated copies of Windows. Instead, it reflects Microsoft’s broader strategy to ensure that users remain engaged with its products and services, regardless of their licensing status.
