As we venture further into 2026, the landscape of operating systems continues its rapid evolution. Microsoft’s Windows 11 remains a significant player, but its installation requirements, particularly around hardware, still spark questions. One of the most talked-about components is the Trusted Platform Module (TPM). If you’re considering an upgrade or a new build, understanding TPM 2.0 and other hardware prerequisites is crucial. This guide will demystify the essential technology needed to ensure a smooth transition to Windows 11, even as we look ahead to future OS developments. Let’s dive into what you need to know to get your system ready for the latest Windows experience.
To be able to install Windows 11 on a computer, it will be necessary to respect a minimum hardware configuration. This specifies, among other things, the presence of a “Trusted Platform Module” (TPM) in version 2.0. A TPM is a cryptographic safe that allows you to create, manage and store secret keys and very sensitive system data. This component makes it possible to create a computing space totally separate from that of the operating system and access to its data is highly secure, in order to protect as much as possible from a possible hacker who might infect the machine.
Used by BitLocker to encrypt disks
Within Windows 10 the TPM is used in different ways. It is used to encrypt hard drive data, whether as part of “BitLocker Drive Encryption” (available on Pro and Enterprise versions) or its watered-down “Device Encryption” version (available on Windows consumer versions). As part of a process called “Measured Boot”, it also allows you to monitor and verify the various stages of machine startup.
The TPM also makes it possible to generate and store secret keys and cryptographic data for system applications (“Platform Crypto Provider”), and in particular for Windows Hello, the biometric access control function, and Windows Defender, the anti-security software. -malware from Windows. In professional environments, the TPM can also play the role of a smart card (“Virtual Smart Card”) and protect access tokens to various company resources (“Credential Guard”). According to Microsoft, using these different protective measures would reduce the probability of being infected with malware by 60%.
A component now very common
In short, TPM is today an essential security brick on which more and more features of Windows and third-party applications are based. And under Windows 11, this component will inevitably gain in importance. To run Windows 10, the presence of a TPM 2.0 is not mandatory. However, Microsoft has forced its manufacturing partners to integrate one systematically since July 2016. If your PC is not too old, then there is a good chance that you have one. If it is not enabled, you can do so through your UEFI BIOS menu.
What does a TPM actually look like? In the past, these components have systematically taken the form of a stand-alone chip, soldered to the motherboard, and connected by an LPC or SPI bus. With version 2.0, this module can also be implemented at the firmware level as a separate execution space. These “firmware TPM” (or fTPM) save space on the motherboard and save energy while having a similar level of security. It is the most common form of TPM and the major chip vendors have such technology. It is called “Platform Trust Technology” (PTT) at Intel, “fTPM” at AMD, and “TrustZone” at ARM.
Windows upgrades from mobile OS
If Microsoft now requires the presence of a TPM 2.0 for Windows 11, it is to raise the general level of security of its operating system. As computer attacks become more and more sophisticated, bypassing a cryptographic vault today would be suicidal. The actors of the mobile world have understood it well. Android and iOS smartphones have had a kind of TPM for years, called “TrustZone” and “Secure Enclave” respectively. Moreover, Microsoft cannot be satisfied with the previous version of TPM 1.2, whose services offered have become obsolete. Indeed, it only integrated the SHA-1 and RSA cryptographic algorithms, knowing that AES was optional. Its successor offers a much stronger palette, adding SHA-256, ECC, HMAC, and 128-bit AES.

Beyond TPM: Evolving Hardware Needs in 2026
While TPM 2.0 remains a cornerstone requirement for Windows 11, the tech world in 2026 is increasingly focused on broader system performance and security integration. Modern processors with enhanced AI capabilities and improved power efficiency are becoming standard, aligning with Windows 11’s focus on a responsive user experience. Furthermore, the push for robust cybersecurity means Secure Boot compatibility and updated firmware are more critical than ever. With an estimated 75% of new devices shipping with TPM 2.0 enabled by default in 2026, compatibility is less of a hurdle, but understanding how these components work together ensures optimal performance and future-proofing.
More Questions Answered (2026)
Does my laptop from 2026 need TPM 2.0 for Windows 11?
Yes, TPM 2.0 is a mandatory requirement for Windows 11, even for devices purchased in 2026. Most modern laptops come equipped with it enabled by default, but it’s always wise to verify in your system’s BIOS/UEFI settings.
What if my PC doesn’t have TPM 2.0? Can I still install Windows 11 in 2026?
Officially, Microsoft does not support Windows 11 installations on systems without TPM 2.0. While unofficial workarounds exist, they are not recommended for stability, security, or future updates.
