While the official tool gives a binary "Yes/No" result, the enthusiast community quickly developed alternatives (such as and ReadySunValley ).

The Windows 11 requirements check is more than a compatibility test; it is an enforcement mechanism for a new standard of hardware security. While the immediate user impact includes hardware obsolescence, the long-term technical goal is to establish a standardized environment where virtualization-based security and hardware-rooted trust are guaranteed. As the OS matures, the validation mechanisms are likely to tighten, phasing out the "soft floor" exceptions to ensure the integrity of the Windows ecosystem against sophisticated cyber threats.

At its core, the Windows 11 requirements check is a binary audit. It scans a computer for four non-negotiable components: a 64-bit processor with at least two cores running at 1 GHz, 4 GB of RAM, 64 GB of storage, and—most controversially—a Trusted Platform Module (TPM) version 2.0 and Secure Boot capability. The TPM requirement is the true differentiator. In previous Windows versions, this dedicated crypto-processor was optional, primarily used by enterprise IT departments. By making TPM 2.0 mandatory, Microsoft effectively told millions of users that their perfectly functional 5-year-old PC was now a security risk. The requirements check is thus a physical manifestation of Microsoft’s new security-first doctrine, forcing a hardware floor that ensures every Windows 11 machine can support virtualization-based security, hypervisor-protected code integrity, and advanced credential protection.

Your hardware is unsupported (often due to an older CPU or lack of TPM 2.0).
