Windows 11
Has anyone else noticed that Windows 11 setup does not check for TPM if it is being installed in a VM? I've installed it on a Gen 1 Hyper-V VM and also a BHYVE VM running under TrueNAS (FreeBSD). Neither of which have TPM and it installed just fine with no complaints.

    Fast!
So the real way to "upgrade" older hardware then becomes: install Windows 11 to a VM, then add the vhdx to the boot menu and you're golden. As long as you can keep updating the virtual machine and adding it to the boot menu, everything is copascetic. Interesting! Lends new impetus to the old "where there's a will, there's a way" saying.

    Purchased early 2019 as Windows Insider test PC
I installed the leaked copy of W11 in Hyper V. I then moved the .vhdx file to a new partition to dual boot W11 / W10. W11 somehow activated and found all the drivers needed. I then joined the Insider program which updated my unsupported PC as below but with a nag screen.

Hi there
Also installs on KVM/QEMU without addition of TPM in the Virtual Machine's config

However the Virtual machine allows an Emulated TPM even if there isn't one in your BIOS and that also works fine

For those on Linux boxes who want to emulate a TPM then install package swtpm with dependents possibly called libtpms and ensure it's started - re-boot the system and VBOX / VMWare VM's .

For KVM/QEMU :

To use swtpm with libvirt, add the following TPM device to the guest XML specification: (or if you have the VIRTMANGER GUI) then simply choose the "add hardware".

<devices>
<tpm model='tpm-tis'>
<backend type='emulator' version='2.0'/>
</tpm>
</devices>
libvirt will start swtpm for the guest automatically; you do not need to start it manually in advance. The corresponding permall file will be created in /var/lib/libvirt/swtpm/VM_UUID.

For HYPER-V VM's on WINDOWS HOSTS I think the TPM emulator is built in to the VM if you add it to the config.

Emulator is provided for Windows HOSTS by Ms and for Linux HOSTS by IBM.

I confirm that installing Windows 11 in a VMWare virtual machine also doesn't check for compatibility and it also installs in Legacy (BIOS) mode. You can first install Windows 11 in a virtual machine, then mount a physical hard disk or SSD and then clone the virtual disk into the physical. Try booting that disk in the host computer. It should load Windows 11 without any issues and then update any drivers needed. Bingo! You run Windows 11 on an unsupported machine in Legacy mode without TPM!

PS: I saw that Windows 11 comes without any browser, not Microsoft Edge, not IE 11. To be able to browse the internet, make sure you download from another computer the Microsoft Edge offline installer or whatever other browser you want. I would also download all Windows 10 drivers for the target computer in order to install them in Windows 11.

    Legacy MBR installation, no TPM, no Secure Boot, no WDDM 2.0 graphics drivers, no SSE4.2, cannot get more unsupported ;) This is only my test laptop. I had installed Windows 11 here before upgrading my main PC. For my main PC I use everyday see my 2nd system specs.
