Windows 8 and later have native support for TPM 2.0. Windows 7 can install an official patch to add TPM 2.0 support. [92] Windows Vista through Windows 10 have native support for TPM 1.2. The Trusted Platform Module 2.0 (TPM 2.0) has been supported by the Linux kernel since version 3.20 (2012) [93] [94] [95]
The Microsoft products Windows Vista, Windows 7, Windows 8 and Windows RT make use of a Trusted Platform Module to facilitate BitLocker Drive Encryption. [22] Other known applications with runtime encryption and the use of secure enclaves include the Signal messenger [23] and the e-prescription service ("E-Rezept") [24] by the German government.
[6] [7] BitLocker was briefly called Secure Startup before Windows Vista's release to manufacturing. [6] BitLocker is available on: Enterprise and Ultimate editions of Windows Vista and Windows 7; Pro and Enterprise editions of Windows 8 and 8.1 [8] [2] Windows Embedded Standard 7 and Windows Thin PC; Windows Server 2008 [9] and later [10] [8]
The static chain of trust starts when the platform powers on (or the platform is reset), which resets all PCRs to their default value. For server platforms, the first measurement is made by hardware (i.e., the processor) to measure a digitally signed module (called an Authenticated Code Module or ACM) provided by the chipset manufacturer.
Windows AIK version 3.0 is exactly the same as 2.0; the version number has only been updated to correspond with the release of Service Pack 1 for Windows 7. [7] Microsoft has also released a WAIK supplement for Windows 7 SP1. WAIK readme [8] references the WAIK supplement, [9] which optionally adds WinPE v3.1 to a previously installed ...
[6] [7] [8] Because PSP is the chip that decides whenever the x86 cores will run or not [citation needed], it is used to implement hardware downcoring, specific cores on the system can be made permanently inaccessible during manufacturing. The PSP also provides a random number generator for the RDRAND instruction [9] and provides TPM services.
However, it is still possible to manually upgrade using an ISO image (as Windows 10 users on those processors will not be offered to upgrade to Windows 11 via Windows Update), or perform a clean installation as long as the system has Trusted Platform Module (TPM) 2.0 enabled, [48] but the user must accept that they will not be entitled to ...
If the installation process started from booting off the media, the user is then presented with a text-based interface which gives three options 1) install Windows, 2) repair an existing installation, or 3) quit setup. [3] If the user decides to install Windows, they are presented with an agreement that must be accepted for Setup to continue.
