update Window 10 to W11

I wanted to update Win10 to win 11 but although I have a fairly new PC ut misses TPM
I read that you can still install windows 11 by just adding DWORD-registervalue AllowUpgradesWithUnsupportedTPMOrCPU and the value 1 to HKLM\ SYSTEM\ Setup\ MoSetup. I then loaded the Windows-11 iso on a USB stick but it sill says it can't install because of missing TPM ? Does anybody know what to do next?

In this video, i will upgrade Windows 10 to Windows 11 on unsupported computer hardware. Although Windows 11 has a higher system requirement, you may still be able to perform an upgrade on an unsupported computer. The Windows setup has an “appraiser” service that checks to see if your computer meets the minimum hardware requirements for that version. It’s possible to replace the appraiserres.dll file in the Windows 11 setup with one from an older build of Windows 10. In order to replace the Windows 11 DLL with one from Windows 10, you’ll actually need the setup files for Windows 10.

Does the motherboard have a socket for the TPM/Trusted Platform Module on it? Find the manual for it that has a drawing/image of the board to check. Then shop for the module.

I've done a couple Notebooks that don't meet the specs. and seem to be fine, even did the last update. I used the bootable USB drive made by the MCT/Microsoft's Media Creation Tool, replaced that one file in it as mentioned in the video and ran the Upgrade using setup.exe on the drive while booted to Win10.

It could be just that TPM is turned off in the BIOS. Modern processors can have a firmware version of TPM that will meet the Win11 requirements. For an AMD processor it's call fTPM, for an Intel processor like the one in your specs it's called Platform Trust Technology (PTT). Check the Security section of your Bios and see if you can find and enable PTT.

If not, then you can, as you say, bypass the TPM check. You made that change in the registry of your PC, didn't you?

Are you booting from the USB to do a clean install? If so, that is not the OS that's running during the install, so you changed the wrong registry. Where you need need to make that change is in the OS that is running after you booted from the install usb. At the screen with the 'Install' button, press Shift+F10 to bring up a command prompt and do it there with the command:
reg add HKLM\System\Setup\LabConfig /v BypassTPMCheck /t reg_dword /d 0x00000001 /f

(Edit: having just typed that, I see that you may not have put the registry change in the right place - it doesn't go in MoSetup, at lest, not for a clean install.)

Or do you want to upgrade your existing Win10 to 11? If so, there's another workaround you can use. For this to work you need to be disconnected from the internet. You start the upgrade by mounting the ISO and running the Setup.exe you'll find there.

When you get to the 'Choose how Setup downloads updates' screen, delete C:\$WINDOWS.~BT\Sources\appraiserres.dll and replace it with a dummy empty one. Make this by creating a new text document on your Desktop and rename it as appraiserres.dll. Then select 'not right now' for the update checks and continue with the upgrade. It will skip all the hardware checks and allow you to upgrade to 11.

aha, thanx a lot. I am going to study your answer. Funny, I made (all four) of the regedits ... in the wrong OS
I shall first see if i can turn TPM (PTT) in the bios on and otherwise try the other route.

One question though I didnt understand booting from an usb is a clean install? I wanted a upgrade from W10 to W11

I just plug the USB into a port, open File Explorer in Win10 and run the setup.exe file on the USB. Booting to the USB or DVD gives more choices but also easier to lose files and programs, clean install wipes the Boot/System/OS drive.

It wasn't clear from you question whether you wanted to upgrade from 10 to 11, or do a clean install of 11, so I covered both possible answers.

Your i5-9600K seems to have PTT, so the only question is does your motherboard's bios support using PTT and have the switch to turn it on?

It is pcspecialist. So it is almost certain to be a consumer 300 series motherboard. Asus z390 at a guess.
