To bypass CPU and TPM checks when installing Windows 11 from DVD or USB drive, put Win11CleanInstallBypassCPUandTPMchecks.reg where you'll have access during setup, such as on the USB install media, or another thumb drive if using DVD.  At the first screen of Windows Setup where it asks about your country, press Shift-F10 to get a command prompt and apply the .reg file by invoking:

regedit Win11CleanInstallBypassCPUandTPMchecks.reg

Close the command prompt and install should proceed without a judgemental block ;)

Of course Microsoft (and my wallet) would be happier if you bought a new PC to pump up that Windows revenue.
