Microsoft said Friday that the company is relenting somewhat on its minimum requirements for Windows 11, allowing enthusiasts that understand the risks to download and upgrade Windows 11 on older, unsupported hardware. Exact details remain murky, however, due to conflicting reports and the lack of an official Microsoft statement.
Users who choose to download a standalone Windows 11 ISO file (as explained in how to upgrade to the Windows 11 beta) will be permitted to run Windows 11, even if the PC doesn’t technically qualify for the OS upgrade. Reports by ZDNet, The Verge, Windows Central, and Thurrott.com all included unsourced attributions from Microsoft spokespeople that say users will be able to run Windows 11 on unsupported hardware. Some of the publications implied that there will be a set of minimum hardware requirements that Microsoft will enforce, while others simply ignored them.
Update: After publication, Microsoft PR responded to PCWorld with details about what is needed to run Windows 11, and a big gotcha—unsupported PCs won’t receive updates via Windows Update.
But what requirements? Here’s what each publication had to say. The murkiest detail appears to be whether TPM hardware will be required to run Windows 11 on an unsupported PC.
- The Verge: “But for those happy to install Windows manually, the actual minimum Windows 11 specs mean that CPU generations don’t matter, as long as you have a 64-bit 1GHz processor with two or more cores, 4GB of RAM, and 64GB of storage.”
- Thurrott.com: “Behind the scenes, Microsoft will allow enthusiasts who wish to upgrade non-compliant older PCs to Windows 11 to do so. These upgrades will not be officially supported, but those who wish to manually upgrade a PC to Windows 11, either by keeping it in the Windows Insider Program or by manually creating Windows 11 install media with the Media Creation Tool, will be allowed to do so.”
- ZDNet: “But if you have TPM 1.2 enabled, 64 GB minimum of storage, 4 GB of RAM and a dual-core CPU, minimum, you will be able to proceed with the installation of Windows 11, though you’ll be notified that your upgraded device will be in an unsupported state.”
- Windows Central: ”The only requirements that will be checked during a manual upgrade or install are whether or not the PC has TPM 1.2 enabled, 64GB minimum storage, 4GB RAM, and a dual-core CPU.”
For its part, Microsoft still seems to be saying that Windows 11 will require a minimum set of hardware requirements, most of which haven’t changed. “We have concluded that the compatible 64-bit processors selected, 4GB of memory, 64GB of storage, UEFI secure boot, graphics requirements and TPM 2.0 are the right minimum system requirements to deliver on the principles we established to best support you,” a blog authored by “the Windows Team” said Friday.
To be clear, Microsoft’s blog post did not publicly state that users would be able to download and install Windows 11 on unsupported hardware. PCWorld asked Microsoft representatives for comment, and we’ll update this post when we receive a reply.
PC Health Check is back
Formally, it appears that Windows 11 still includes a list of minimum hardware specifications. But it’s still unclear whether an “unsupported” Windows 11 PC requires a minimum hardware specification and what that hardware requirement actually is. Remember, one of the key issues surrounding Windows 11’s hardware requirements was the need for a Trusted Platform Module (TPM), and what version of the TPM that required. The reports published today with details from Microsoft spokespeople were split on whether TPM will be needed to run Windows 11 on unsupported PCs, as noted above.
Microsoft did, however, expand the list of supported CPUs to include several Intel chips: Intel Core X-series, the Xeon W-series, and the Intel Core 7820HQ, which features in the Microsoft Surface Studio 2. (Technically, the Surface Studio 2 is among “select devices that shipped with modern drivers based on Declarative, Componentized, Hardware Support Apps (DCH) design principles.”) Microsoft also said that its had carefully analyzed the first generation of AMD Zen processors and concluded that it would not be adding any of those processors to the approved list.
Finally, Microsoft said that it would be releasing an updated version of the PC Health Check app that it had pulled earlier. The new app (shown at the top of this article) includes “more complete and improved messaging on eligibility and links to relevant support articles that include potential remediation steps.” Of course, the PC Health Check app means little, if enthusiasts can still install a standalone Windows 11 ISO file on hardware that the PC Health Check app would seem to reject.
We know that those users who own older PCs should be able to run Windows 11 eventually. But did Microsoft really clear up any of the issues surrounding Windows 11 on Friday? We’d say no. It certainly could have, by spelling out the details in an official statement. But by releasing information privately to four publications—each of which reported the issue slightly differently—Microsoft simply confused the Windows 11 issue even further.
