    The potential for Court cases and damages being awarded has a way of getting minds focused oto push some sort of solution out there asap.

    Now that it is in the open and people know about it, it is certain people will create means to exploit it IMO

    Intel should be forced to stop selling new pc.
    Though that would be impractical

    yeah Dell + VMware (IIRC?) has pulled all patches as well.

    Glad I only applied linux microcode package to my home server and held off on my laptop BIOS, so easy to gank if there's any issues

    I applied microcode on my z370 gaming 7 and Windows 10 patches. I haven't noticed anything though.

    As a tech I have, people's Windows 10 PCs keep randomly rebooting.

    So. Perhaps that's why my PC has been randomly rebooting seemingly without cause. Good to know.

    I installed the 1.40 bios (microcode security fix) on my Asrock Z370 Taichi before it was pulled from dowload, haven't noticed any problems.

    the reboots were allegedly haswell/broadwell but now vague statements/reports re: affecting everyone. But all the chatter is on haswell/broadwell so not surprised if Z370 hasn't seen an issue

    1) This is how these things work. Someone discovers it one day (usually by accident), and we have to move fast to patch it, given how important computers are. See Heartbleed, and similar large scale exploits.

    2) Who are these "tech gurus" you talk about? Security research is bloody hard, and there's not a huge number of these people doing the very, very cognitively difficult work. Try it for yourself with a little game: https://www.microcorruption.com

    Pro Tip: Your average knob IT tech or helpdesk jockey isn't a security researcher.

    And the progress of this whole sordid business descends into complete and utter clusterfuck.
    Microsoft Issues Windows Out-of-Band Update That Disables Spectre Mitigations.
    Yes, folks, Intel's microcode is so bad that MS have rolled out a KB4078130 that rolls back the microcode patch, and provides info on how to selectively enable and disable the microcode. Win7 through 10, and relevant server versions and it's an OOB update too.
    Can Intel have handled this thing any worse?????? I doubt it.

    Why isn't Microsoft using retpoline instead, like Linux?
    And how does a company like Intel produce an unstable microcode fix despite knowing about the vulnerability for so long?

    Well, maybe the reason Microsoft aren't using retpoline is because they don't have someone like Linus Torvalds who isn't afraid to just say he thinks a patch is shit.
