I have just been informed by Dell tech support that my Aurora R9 Intel Core i9-9900K CPU 3.60GHz Coffee Lake-S processor is not compatible with Windows 11 core isolation memory integrity. So I cannot turn on memory integrity on this PC and there is nothing Dell can do about it as it an Intel problem with this particular processor.

Gutted as this PC is only 2 1/2 years old and now has a security issue that cannot be fixed. Is anyone else having the same issue? I believe it's only relevant to Intel Core i9-9900K CPU 3.60GHz Coffee Lake-S processor.
