Microsoft recommends installing the June/July preview releases. But even then server performance maybe be degraded by 2% or so.

In an email, researcher Pietro Borrello of the Sapienza University of Rome wrote, “From our point of view, disabling APIC MMIO and enforcing x2APIC from the microcode would have been a more effective mitigation with no performance impact (actually, it would have had a performance improvement). However, we do not know why they chose to flush buffers and disable hyperthreading, thus [requiring] a possibly costly mitigation. It may not be possible to enforce x2APIC internally, or they may have chosen this path for compatibility reasons.”

at first, for the "aepic" part of the name i thought it was an AMD server chips vulnerability

Don't care / don't want your so-called 'fixes' that break performance, especially foisted upon people in the form of firmware updates that are often released with other critical bug fixes, usually meaning you don't have a path to disable the mitigations. It seems inconceivable to many that systems can be protected at the edge and inside therefore negating the need for mitigation @ a microcode level.

I believe this is Intel Xeon Server CPUs only, the SGX setting is disabled by default in every bios, and has already been patched in the June and July Windows Updates. Please correct me if I am in error, gents.

Hell yeah! One of the best perks for intel chips HAHAHAHAH.

https://ark.intel.com/content/www/us/en/ark/search/featurefilter.html?productType=873 Filter by SGX ja use other filter to limit the results, say by clock speed to see of some cpu is on the list. 12600K (which should be delivered to me in in say 1h) was not on the list.

the windows updates had nothing to do with SGX.

How about SQUIP vulnerability on zen cpus?

They only attack intel here I believe.

another issue that needs physical access.

That makes it even more dangerous, since it's so easily disregarded and it's extremely easy to get your hands on a company laptop.
