Microsoft closes the door on Windows 11 supporting older hardware
Image: Microsoft Microsoft has poured cold water on any hopes of lower hardware requirements for Windows 11. With Windows 10 end of support approaching in October 2025, the software giant now says that its Trusted Platform Module (TPM) 2.0 requirement for Windows 11 is “non-negotiable.” In a blog post entitled “TPM 2.0 – a necessity for a secure and future-proof Windows 11,” Microsoft makes it very clear that it won’t lower Windows 11’s strict hardware requirements to encourage people to upgrade from Windows 10. TPM was a surprise requirement for Windows 11 when it was first announced in 2021, and now practically every modern PC ships with support for TPM 2.0. It’s a hardware-level chip or firmware capability that helps encrypt or decrypt data, confirm digital signatures, and assist with any other cryptographic operations. “TPM 2.0 plays a crucial role in enhancing identity and data protection on Windows devices, as well as maintaining the integrity of your system,” says Steven Hosking, a senior product manager at Microsoft. “TPM 2.0 also helps future-proof Windows 11. One way it does so is by helping to protect sensitive information as more AI capabilities come to physical, cloud, and server architecture.” Microsoft details how TPM integrates with new security features in Windows 11 like Credential Guard and Windows Hello for Business, as well as BitLocker disk encryption. TPM 2.0 also helps support Secure Boot, a key technology that secures the boot process from any unauthorized changes. Hosking says Microsoft has implemented TPM 2.0 “as a non-negotiable standard for the future of Windows,” so there’s no going back on the hardware requirements here. Microsoft also requires that Windows 11 devices are capable of virtualization-based security and hypervisor-protected code integrity (HVCI), which means Windows 11 is only supported on CPUs released from 2018 onward. Despite the requirements, there have been several workarounds over the years to allow Windows 11 to run on unsupported hardware. Microsoft didn’t apply a hardware-compliance check initially for virtualized versions of Windows 11, but the company has been gradually locking down the upgrade and setup process in recent years — especially with the 24H2 update. The improved compatibility checks with 24H2 have forced tools like Flyby11 to leverage a feature of the Windows 11 setup that uses a Windows Server variant of the installation to bypass the hardware compatibility checks. Businesses can also use Microsoft’s official Windows 11 LTSC 2024 release, which makes TPM an optional requirement but still enforces a list of compatible CPUs. Microsoft is now trying to convince Windows 10 users to buy a new PC with full-screen prompts. The latest prompts follow warnings about the Windows 10 end of support date earlier this year. Microsoft has used similar prompts like this in the past, with the company pushing Windows 10 upgrades for Windows 7 and Windows 8.1 users.
