While the demand for a TPM 2.0 device is needed to protect the system, simply dropping 32-bit platforms seems to be all that need be done.

Consumers will still need to go to the effort of downloading an ISO file and manually installing Windows 11, which the vast majority probably won’t do. 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.

Microsoft has been testing Windows 11 on older machines and so far it has been a mixed bag. Most of the problems are related to drivers. DCH drivers are called Declarative, Componentized, Hardware Support Apps.

The TPM chip is available to connect to a header for most AM2, AM3 and AM4 platforms. Intel boards vary with TPM support that I have seen. Microsoft said testing on AM4 with Ryzen 1000 processors lead to a lot of BSOD crashes suggesting there is a compiler fault. This suggests older processors with UEFI motherboards will still fail. Guess there is some work for a compiler developer.

Even the old Sandy Bridge i3-2100 machine has UEFI and secure boot but the Asus motherboard is very low cost model with few other features. The machine transected the migration to UEFI and GPT as the original BIOS was upgraded as it was developed and published. The last BIOS was fully UEFI and it can boot larger hard disks. The integrated HD 2000 graphics supported a basic display.

Microsoft is now planning to update its PC Health Check app (a preview is available here) to include the new Intel CPUs and provide much greater clarity on why your PC might not be able to officially upgrade. The new PC checker app will let Windows users know if they need to simply enable Secure Boot or TPM 2.0 to upgrade, TPM hardware will be manufactured for older UEFI machines which have been on the market for about 10 years now.


Gaming does want a much more power processor, more memory and more storage over the minimum machine. Windows 11 should run well with 16GB of RAM with a recent graphics card. AMD B550 and X570 are both fine platforms for Windows 11. Intel’s new hardware now supports PCIe 4.0 so now their fans can use the faster SSD products.
