W11 on unsupported hardware. Did what it said on MS site. No joy ?

I have spent the past few hours trying to install W11 on a unsupported W10 PC.
Version 22H2 (OS Build 19045.4291)

The workaround given on the MS site has been followed, except the English version on my PC is GB English.
This version was not available on the language choice prior to downloading the ISO, so I selected International English for the download.

The attached image shows my edit of the registry for this purpose.

I have used Rufus to mount the ISO in a folder on my desktop.

Windows is still giving me the error message about the need for secure boot and TPM.

It then stops the process.

Ticking the appropriate boxes in Rufus does not solve the problem.

Any suggestions ?

Install the Aveyo bypass, download the iso. and do the upgrade from within Windows!

I upgraded a 10 year old non-complaint PC last week as follows:

1. Download the latest Windows 11 ISO file and mount it as a virtual drive
2. Turn off net access
3. Run setup.exe
4. On the first screen click 'Change how Setup downloads updates' and select 'Not right now'.
5. Replace C:\$WINDOWS.~BT\Sources\appraiserres.dll with an empty dummy file. Use Notepad to make a new text document renaming it as appraiserres.dll. You can now continue the install and it will skip the compatibility checks.

That's alright.
International English = GB English
[These days, English = US English]

And you'll need to create a dummy appraiserres.dll file as explained in some posts above.

You don't even need to do those workarounds --from the iso image (get from UUPDUMP etc) and simply run dism /ApplyImage .... etc then run the bootloader bcdboot.exe to the EFI partition on your target disk. Rufus also might still work.

This method also works if you use physical vhdx files too.

Note these methods mean you have to install from new -- not upgrade an existing build.

Aother get_around -- especially if you want to UPDATE an existing build via Windows update is to have a version in a VM -- the VM hardware can run on almost any real hardware - you can emulate TPM's, alter cpu topography etc -- update the build and then copy to a real system - windows can update the required physical drivers -- easier though if you copy those to a separate file from an existing real machine and after booting the "cloned VM" update the drivers from the saved file.

And did you check Secure Boot and TPM? It should work, at least till 24H2.

I think even 10 year old computers had secure boot available so I'm not sure if that's a real issue. If the computer is only MBR / BIOS with no UEFI support / boot then Rufus might be the only answer as I'm not sure if bcdboot.exe would install to the disk with the /MBR parameter without an error.

Might be interesting to test on an old Sony VAIO laptop I've got around somewhere -- that's only MBR boot.

It worked for Windows 10 - but Windows 11 -- ????

Load the system hive of the installation media \sources\boot.wim image 2

make the reg changes and unload the hive.

One easy way is to use 7-zip to insert the .cmd file that will do it on the fly


The installation media has to be writeable.

Extract iso contents to usb stick will be fine as it will be writeable.
************************************************************************


The long way is mount boot.wim image 2



1. create an empy folder to mount the wim image

md %systemdrive%\mountfolder

2. mount the bootable wim image into that folder ( in ms install media boot.wim image 2 is the bootable image by default )

if the usb stick is E:

DISM /Mount-image /imagefile:E:\sources\boot.wim 2 /MountDir:%systemdrive%\mountfolder

3. In regedit or some 3d party reg editor, load the hive %systemdrive%\mountfolder\windows\system32\config\system

or use reg.exe

reg load HKLM\SOMENAME %systemdrive%\mountfolder\windows\system32\config\system

4. make the reg changes

reg add "HKLM\SOMENAME\Setup\LabConfig" /f /v "BypassTPMCheck" /t REG_DWORD /d 1
reg add "HKLM\SOMENAME\Setup\LabConfig" /f /v "BypassSecureBootCheck" /t REG_DWORD /d 1
reg add "HKLM\SOMENAME\Setup\LabConfig" /f /v "BypassRAMCheck" /t REG_DWORD /d 1
reg add "HKLM\SOMENAME\Setup\LabConfig" /f /v "BypassStorageCheck" /t REG_DWORD /d 1
reg add "HKLM\SOMENAME\Setup\LabConfig" /f /v "BypassCPUCheck" /t REG_DWORD /d 1


5. unload the hive

reg unload HKLM\SOMENAME

6. commit the changes and unmount the wim image

Dism /Unmount-Image /MountDir:%systemdrive%\mountfolder /Commit

Those of us who have a strange obsession with pe building do this mounting and loading stuff all the time. It is probably incomprehensible to the average punter.

The 7-zip method linked in my previous post is a lot easier and quicker for most people.

Yep !
Like you say.
