Windows 11 has other system requirements, though they weren’t the focus of this TPM-centric blog post. Windows 11 systems must have Secure Boot enabled, and they have to use a supported processor—an 8th-gen Intel Core CPU, an AMD Ryzen 2000 CPU, or a Qualcomm Snapdragon 850 CPU or newer. In fact, these CPU requirements exclude a couple of generations’ worth of Intel and AMD chips with built-in TPM 2.0 support.
Windows 11 also has nominal requirements for RAM and processor speed, but any system that meets the CPU or TPM requirements will easily clear those bars. If you have a supported CPU and your PC doesn’t appear to support TPM 2.0, you should be able to enable it in your system’s BIOS, either manually or by installing a BIOS update for your motherboard.
Windows 11 can be installed on unsupported systems, either those with an older TPM 1.2 module or no TPM enabled at all. It’s more annoying to install major updates on those systems, and Microsoft reserves the right to pull updates from those systems at any time, but aside from that, Windows 11 usually runs about as well on these PCs as Windows 10 did.
