I made a bootable Windows 11 using the official media creation tool and unable to install Windows 11 on my computer. It says this PC does not meet the system requirements to run Windows 11. Actually, the hardware specs are decent though it was bought years ago. It is Intel i7 6600U with 16GB RAM.
How can I install Windows 11 on unsupported CPU? In addition, this PC has Secure Boot and TPM 2.0.
IIRC you need 8th gen or later to install Windows 11 officially.
Last time I tried Rufus had an option to bypass the requirements, it should pop up after you click START to create bootable USB from downloaded ISO.
Media creation tool can be set to only download ISO if you tried directly to USB.
I’m sure Microsoft is working hard to mess things up for unsupported platforms, so use at your own risk.
Had a hell of a time installing on an Intel Xeon E5649 last week. Had to back all the way to the Windows 10 release to manufacturing (RTM) from July 2015. I was nearly done exhausting the tricks found to get around the requirements. If they installed at all, they never got past the Windows startup logo.
You might be stuck with the Windows version you installed, if feature or version upgrade do a second check. But yeah, Rufus should have a option to bypass hardware check - also check the “create local user account” while you are at it in order to circumvent the MS account shenanigans .
Welcome to the forum
I tend to use the program Ntlite (best program to do anything with windows)
But for your particular situation try this
If you want to install Windows without any tools, you can create the USB installer and start the setup.exe with the “/product server” flag. It won’t ask for any security requirements, but it’ll want to be a fresh install, you only get to keep your documents.
Rufus is your friend. It will easily create a boot usb with a patch to bypass W11 requirements, I’ve checked it myself. Recently installed W11home on a first generation i3 without tpm.
If your CPU is an Intel i7 6600u, it wouldn’t have Secure Boot and TPM 2.0.
You’re only hoping to install Windows 11 to figure out how to by pass the compatibility checks of the installation USB. I have had good luck bypassing the above-mentioned check with Windows 10 but not Windows 11.
Rufus provides appropriate options to bypass all this when creating the installation media.
I installed W11 on a machine with 6GB of RAM, with a first generation i3, without SB and TPM, it works as it should. 
Unless you mean some checks later over time?
If I find the time, I will try to install W11 on a core2duo with 4GB of RAM.
I followed the following steps to create a custom ISO file for a Windows 10 VM: Create a custom Windows 10 ISO and use that custom Windows 10 ISO to create a Windows 10 VM. The same procedure didn’t work when I created a Custom Windows 11 ISO to create a Windows 11 VM.
Yeah, I had trouble installing on first gen Ryzen, even with Infineon TPM 2.0 plugged into MB. Funny thing was I used it for Proxmox and it had no trouble emulating TPM 2.0 for virtual Windows 11 install.
You can bypass the CPU check by modifying the registry during installation. Press Shift + F10, open regedit, and create a key called LabConfig with DWORD values BypassCPUCheck and BypassSecureBootCheck set to 1.
You can try the following trick if the above tricks did not work. I created two bootable USB drives and installed Windows 11 on an Intel i5 6500 CPU, which is not official supported by Windows 11.

p.s. I tried the product server command but it does not work for Windows 11 24H2.
Burning the disk image with Rufus is quick and painless. However, be aware that Microsoft could (intentionally or not) brick your install down the road with an update that expects certain hardware capabilities that your system lacks.
i had to do some things to get windows 11 on a vm.
i had to set a registry flag of the winPE
iirc (please correct me if im wrong) it was
in hkey_local_machine/system/setup, make a new key called LabConfig. inside LabConfig, make the folloing 32-bit dwords and set them to 1.
BypassTPMCheck
BypassCPUCheck
BypassSecureBootCheck
BypassRAMCheck
This has already happened on my install attempt with Windows 10 RTM. The initial install worked. After Windows Update for drivers and the works… non-responsive desktop.
I’ve been experimenting more with that flag, and I get it to work from within an active Windows install (i.e. I started the setup from within another Windows install)
Come to the Dark Side.
Install Linux.
There is still value in having Windows for sure. I’d rather virtualize it but I cant do a good enough job for it.
My 6700K Z270 rig does have TPM 2.0 enabled according to the health check tool though I had to buy a TPM module so its possible with right motherboard perhaps at least for TPM 2.0 but got to bypass the cpu check.
