Installation of Windows 11 on unsupported old hardware

For models with onsite Warranty, they do come at your place to repair it. For models with carry-in Warranty you have to send it to them.

Running latest build on a 17year old dual core Netburst. Originally shipped with XP.

What a coincidence! I recently installed Windows 11 on the same model!

Not seeing much activity on this thread for really old computers. Are people just not interested anymore or is there another thread/place? The win10 thread has a lot more activity.

There`s already a thread on it.
Old/Incompatible = Same thing
But feel free to keep typing.

Wow that is a very old machine. By the way which method did you follow to install win 11? Is it the reg hack method or another one.

I am testing installing Win 11 using dism command line. I did the test in Virtualbox using the eval ISO. I might test it later in a physical machine and see if it works. I used default Virtualbox settings for Windows 11 (64-bit). Now I changed the memory size to 512 MB and it sill works. However, it is useless as it takes for ever to boot, but at least I knew I can run the machine with less than 1GB Ram. I used compact mode switch for dism.

Just Rufus USB tool. It has a special option to make a patched W11 USB that bypasses all the checks. It was super easy. Easier than I had thought going into it. I guess its a relatively new method?

Not so new. :)

Create bootable Windows 11 ISO without TPM, Secure Boot and RAM requirements.

But is there a Rufus version that skips the CPU check too ?
Version 3.17.1846 does not.

What CPU models are cut off again? I mean I just installed fine on a 17yr old Pentium D.

I think the 7 series is the cutoff ?
I`m not even considering installing 11 on the Z170, seems kinda silly to have back to back PC`s with the same OS on them.
This list shows the 79xxX as a cut, but who knows if that`s still correct.

Yeah the Rufus patch definitely skipped that cpu check if it let me install on a Pentium D. That’s like 2 model paradigms before the spec cutoff.

Pentium 4
Pentium D <- I just installed on
Core 1 Solo
Core 2 Duo/Quad
3xxx series
4xxx series
5xxx series
6xxx series
7xxx series <- spec cutoff

Well that`s good to hear
I still like W10 too so the Z170 will stay as is for now.

The easiest method to clean install Windows 11 on unsupported machines is to create a hybrid USB Flash drive. This is a regular Windows 10 installation USB with the file \sources\install.wim replaced by the respective file from Windows 11 ISO. I use this to install Windows 11 on any computer with Legacy BIOS, without UEFI, without TPM. You create this once, no further hacking required, unless you want to upgrade from 10 which is different method. I have installed Windows 11 on Pentium D and Core 2 Duo computers. See my test laptop (1st system specs).

Rufus plus W11 ISO so easy tho. Don't need W10 ISO, don't need to do any manual steps. I think all the check bypasses are the same?

Yes, Rufus works too. It uses the Windows 11 ISO and patches the Registry, so you don't have to do it during installation. The same USB can be used for either unsupported or supported computers, but it is UEFI only. The hybrid USB Flash drive can be used in Legacy BIOS machines without UEFI support.

Just watched this quick video on it..... for clean install..

Lol don’t even need the ISO Rufus will download it for you. Nice.

Not sure what you mean by UEFI only. The Rufus patched W11 usb installer works fine on my non UEFI machines.

You you can choose MBR or UEFI, look at the snip I posted.
