A Trusted Platform Module (TPM) is a secure cryptoprocessor that implements the ISO/IEC 11889 standard. Common uses are verifying that the boot process starts from a trusted combination of hardware and software and storing disk encryption keys. A TPM 2.0 implementation is part of the Windows 11 system requirements. [1]
As part of the minimum system requirements, Windows 11 only officially supports devices with a Trusted Platform Module 2.0 security coprocessor. [ 43 ] [ 44 ] According to Microsoft, TPM 2.0 is a "critical building block" for protection against firmware and hardware attacks.
For the first time since the release of Windows 11, version 24H2 introduces modified system requirements: A x86-64-v2 CPU supporting SSE4.2 and POPCNT CPU instructions is now required, otherwise the Windows kernel is unbootable. [9] [10] (Only affecting systems bypassing the TPM 2.0 requirement, along with all 24H2 IoT Enterprise editions.)
Thus, Windows 11 is the first consumer version of Windows not to support 32-bit processors (although Windows Server 2008 R2 is the first version of Windows Server to not support them). [149] [150] The minimum RAM and storage requirements were also increased; Windows 11 now requires at least 4 GB of RAM and 64 GB of storage. [151]
Trusted Platform Module 2.0; CPU/chipset/BIOS support for S0ix "Low Power S0 Idle" power state; On Windows 8.1, supporting InstantGo and having a Trusted Platform Module (TPM) 2.0 chip will allow the device to use a passive device encryption system. [4] [5] Compliant platforms also enables full BitLocker Device encryption. A background service ...
Starting with Windows 10 1703, the requirements for device encryption have changed, requiring a TPM 1.2 or 2.0 module with PCR 7 support, UEFI Secure Boot, and that the device meets Modern Standby requirements or HSTI validation.
Furthermore, the TPM has the capability to digitally sign the PCR values (i.e., a PCR Quote) so that any entity can verify that the measurements come from, and are protected by, a TPM, thus enabling Remote Attestation to detect tampering, corruption, and malicious software.
