    I thought Intel farmed out their chip production to other countries?
    Of course Intel designs and engineers the processes, but do they actually psychically build their own chips?

    Yes of course, the question is whether Intel can do something if it will or will "wash hands" because it is more convenient for it to have everyone upgraded. Let's wait for scenes from the next chapters.

    no microsoft patches are software OS updates and microcode is hardware bios integrated and dell suspended many of the december/november bios and re-uploaded a few updated bios' in late january/february 2018 so keep checking to see as they are having many problems related to spectre and meltdown because the OS patch with the hardware bios updates and the intel updates causing problems as a whole so it is gonna be hit or miss the whole year as far as i see and i can see class actions against intel as only real hardware update will work and that may be in intel gen 9 chip as they are rushing it out the door for that release so i think gen 10 is more safer bet :) this is all in conjunction with intel's management engine interface that also had huge holes and that is also a part of the problem as a whole; microsoft posted some insider updates late january and also removed them as they had problems so will see if it is worked out in time for next weeks patch tuesday

    It only sets the reg entries to disable the mitigation.

    Yes....and I should add w7 x64 users should apply the latest fixes ASAP.

    AFAIK for any 32 bit version of windows there is no meltdown patch at all available yet.

    it would seem to me that the whole collection of windose users continue to live in a fools`paradise.they should realise that fundamental design flaws in cpus can never be patched with mere software updates. and that m$ have been very eager to let this illusion continue.they have been less than zealous to patch the unpatchable. unlike the open source comminity. yes i mean linux . they at least gave it a good try.looks as if m$ did not even bother to do that. time to move on. m$ has had its day under the sun, imho.

    The meltdown / spectre thing illustrates a lot.
    Meltdown is based on grubbiness, there are actually countermeasures but for some reasons at Intel CPUs they are not 'applied'.....

    The general point is security versus speed and development with more or less focus on the former.

    But it also illustrates the power of open source and the Linux community.

    Such a community can be more skilled and effective than an old timer capitalist which can pay the best specialists.....even worse they introduced firstly a far bigger hole by their patches....
    Monopolistic orientated companies such as M$ have to fear about their reputation and loss of market shares. Technical skills are not the major focus and a good product = proper fix is secondary.
    The same basically applies to Intel as well.

    To release 'something' to get out of focus is far more important....to create a reason to justify the argument to say...we're doing something against it, we are able and aware.

    In regard to security versus speed/performance I'd say it is not related to one particular company alone, it's rather a general (human) trend that is based on an intention to get superlatives...

    And security to speed is opposite since to have proper security mechanisms costs time.

    There will always be a probability of a risk and finally it's all about mitigation...
