"If your existing Windows 10 PC is running the most current version of Windows 10 and meets the above minimum hardware specifications, it can be upgraded to Windows 11."
My platform meets the minimum hardware requirements including the processor (i7-9700K coffee lake)
There are no other caveats, other than confirming that TPM is required to be enabled in the BIOS to permit the Windows 11 upgrade.
Your reply isn't helpful. As far as Asus are concerned the only requirement for SGX is that it is enabled in the BIOS (which it is). SGX has been functioning correctly under Windows 10. The SGX driver is supplied by Intel, my question relates to the driver and you haven't answered it.
