It seems that Microsoft is allowing Windows 11 to install on machines that may not have the required TPM 2.0.
Trusted Platform Module (TPM, also known as ISO/IEC 11889) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. The term can also refer to a chip conforming to the standard.
On the Microsoft website there are instructions pertaining to the modification of the registry configurations that would allow the Windows 11 installer to bypass the TPM 2.0/cpu check.
Here is the registry edit you’ll need according to Microsoft:
Registry Key: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
Name: AllowUpgradesWithUnsupportedTPMOrCPU
Type: REG_DWORD
Value: 1
Microsoft doesn’t recommend that you install Windows 11 on a machine that doesn’t meet it’s strict requirements, but the installation is allowed — It’s strongly advised however that you should at least have the TPM 1.2 existing on your machine if you plan to install Windows 11 anyway.

Some older machines will function pretty good, while yet others may not — it all pretty much just depends on your processor.
I’ve been running Windows 11 on an HP laptop from the very beginning through Microsoft’s insider program and I haven’t had any trouble with the build.
The specs for the (very slow) HP laptop are:
Intel Core i5-4300M CPU @260 GHz
12GB RAM
64bit
1.2 TPM
This laptop is the oldest/slowest unit I’ve got and I’ll figure it to be a starting point for Windows 11.
My much faster ASUS unit has an AMD Ryzen 5 5600 w/6 cores, runs out at about 32GB RAM, and it thinks that Windows 11 is the Bees Knees.
