Windows 11 has a specific set of hardware requirements. Among them is the requirement for TPM 2.0 or higher, something that makes a lot of PCs incompatible with the OS. Of course, this eligibility criterion didn't stop users from upgrading using unofficial methods, and even Microsoft offered an official workaround in October 2021 to get the requirement bypassed.
This official TPM requirement bypass method required an edit in the Windows Registry. Now, however, Microsoft has deleted the guide that walked users through the official bypass. This doesn't mean that the bypass trick won't work, but it suggests that the company isn't endorsing the method anymore.
So, as it stands, Microsoft appears to be portraying that the only way to get Windows 11 is to install it on a system that meets the hardware requirements. That is, if you're using an unsupported system, the company wants you to upgrade your PC to get the latest OS (Lenovo LOQ 16 with TPM 2.0 and RTX 4060 curr. $799.99 on Best Buy).
That said, the bypass that Microsoft previously shared on the official support site isn't the only way to get Windows 11 installed on unsupported systems. It's also possible to get through the TPM check through Rufus, a free utility that helps to create bootable USB drives.
Besides that, there's a way to bypass the Windows 11 TPM check from the Windows update itself, and for low-end systems, there's Tiny11. Still, the Registry hack being present on the official site would've made things a bit more convenient. It's unclear whether Microsoft is making this change to meet its hardware partners' demands.
