Todays Dev Windows 11 Insider Compilation and TPM 2.0. requirement

I warmly welcome Correct me if I am wrong, but the messages so far indicated that people in the Dev branch of WIndows Insider will not be subject to restrictions on, for example, TPM 2.0 and 8+ ge...

    So, I was able to bypass the problems (skip TPM) and successfully install Windows 11 via Windows Update. It required:
    - adding the "BypassTPMCheck" = dword: 00000001 key in the Win 10 registry (latest Dev Insider OS version )
    - adding the appraiserres.dll file from Win 10 ISO (the latest public version - not the Insider version) to the hidden Windows BT folder after an unsuccessful installation - in place of the file downloaded from the branch by default.

    The system has been updated without a problem and so far everything works fine for me.

The problem is clearly TPM. Reboot and windows update clean up (softwaredistibution cleanup) does not help and the installer insists that the computer must support the TMP 2.0 for WIndows 11 instalation. Recently, I even read articles on several portals, where indicated that the Win 11 installer allowed to install this system on editorial older computers without TPM. However, it looks as if the fault is on the side of the build itself.
Some people pointed to a possible TPM check bypass by moving the appraiserres.dll file from Windows 10 ISO to Windows 11 ISO. I tried this option on 2 versions of appraiserres.dll ie. file (from the last, current dev preview of Windows 10 and the file version with the latest ISO Windows 10 - without preview).
The first method ended with a message that tpm 2.0 and an required version of the processor is a problem (I got a cpu before 8 gen) while the base Win 11 file version indicates only TPM. 2.0. In turn, the file with ISO Win 10 without preview, lets me through the hardware test but stops on the product key screen - without skip option.
Unfortunately, the product key screen does not accept my current Windows 10 Pro key . When I type new Win 10 Pro keys, I get a message that they are not supported in the installed version of Windows 11 😄

Your explanation is confirmed by the TPM2.0 requirement.
this advanced encryption level is the security of the Win11 build.
Maybe Microsoft will introduce a switch for Insiders that would be a temporary solution!
I also will not replace good computers because of Win11.
Good luck!
