Is it yet possible to upgrade a Windows 10 install to Windows 11 with no TPM and unsupported CPU?

[Gimpymoo]

Have looked around, does not seem like there is.

I have a modified ISO but that only allows to do a clean install which would rather avoid.

My 4770K does everything I ask of it, really has been a great little chip, not putting it out to pasture just yet.

Thanks for any help.

Just follow these instuctions to add the registry key and then download the ISO. Installed on my old laptop last night using this method

https://support.microsoft.com/en-us...ndows-11-e0edbbfb-cfc5-4011-868b-2ce77ac7c70e

That method only allows to install on systems which do not have a supported TPM (1.2 and not 2.0) not systems without a TPM of any kind as far as I know.

You literally have you put exactly what you wrote as a the title into Google and you will see how.

I had tried those but was not getting anywhere.

The reason for that was that I was trying to use the inline updater, not running the setup from the standalone ISO.

I followed option 3 here:
https://winbuzzer.com/2021/10/07/ho...e_to_Windows_11_without_any_TPM_TPM_20_TPM_12

Added DWORD "AllowUpgradesWithUnsupportedTPMOrCPU" to Registry Computer\HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup and set value to 1 and rebooted.

I automatically tried the v2 skip TPM check but that did not work, tried the V1 and BINGO.

Ran setup from the standalone ISO and installed rather quick to be fair.

Might have to try this.

Just decided to test mine with their PC health check and got "TPM not detected" and "Processor Intel i7-3770 CPU @ 3.40GHz isn't currently supported!"

Not surprising considering the age the PC

This seems to be the way forward to be honest.. much less faff and almost certain to work..

Very clever way of installing Win 11 on a PC that fails the compatibility checks.

By far the easiest way is to use Rufus it has an option to create a USB stick that bypasses all the checks and acts as a normal Windows install via USB (booting into the USB from Bios)
Download the official ISO from Microsoft and write it to the USB

That method is only for clean installs, not upgrades isn't it?
