How to Check if Your PC Is Protected Against Meltdown and Spectre

Warning: Even if you’ve installed patches from Windows Update, your PC may not completely protected from the Meltdown and Spectre CPU flaws. Here’s how to check if you’re fully protected, and what to do if you aren’t.

Microsoft Says Security Patches Slowing Down PCs, Servers

Microsoft Corp said on Tuesday the patches released to guard against Meltdown and Spectre security threats slowed down some personal computers and servers, with systems running on older Intel Corp processors seeing a noticeable decrease in performance.

The security updates also froze some computers running AMD chipsets, Microsoft said in a blog post, citing customer complaints.

Understanding The Performance Impact Of Spectre And Meltdown Mitigations On Windows Systems

Executive Vice President, Windows and Devices Group

Last week the technology industry and many of our customers learned of new vulnerabilities in the hardware chips that power phones, PCs and servers. We (and others in the industry) had learned of this vulnerability under nondisclosure agreement several months ago and immediately began developing engineering mitigations and updating our cloud infrastructure. In this blog, I’ll describe the discovered vulnerabilities as clearly as I can, discuss what customers can do to help keep themselves safe, and share what we’ve learned so far about performance impacts.

    “The security updates also froze some computers running AMD chipsets,”
    ‘Some’ my ass. It’s been a Worldwide epidemic.
    I already had a previous appointment with my IT guy for another matter so I lucked out and jumped the que, looking for emergency service this morning
    I hope those affected sue Redmond’s ass off.

    I am not technically stupid in that I have ad-blockers, and malware stoppers and antivirus scans. But, I am pretty much technically illiterate in that what do I need to do and when should I do it and how fucked am I, really? 😛

      Update your BIOS (and hopefully your MoBo manufacturer has an update), and update Windows 10
      That’s about all you can realistically do.

      My daily driver is about 8-years out of current fashion, so other than updating Windows 10, there’s not much else for the average user to do.

    Now all your Intel machines run like my shitty AMD machines that didnt get or need the patch

    Never go first.
    Just keep current on the agonies of those who do.

  • Something stinks.

    a) it will probably eventually require another hardware upgrade (for the umpteenth time)
    b) which means it will require another endless circle of compatible OS and software upgrades, followed by more new hardware again — a vicious circle.

    Who benefits? The computer industry in general — millions of people upgrading again, both hardware and software, billions of $ in new profits.

    And as we move from BIOS to EFI to UEFI, more hardware control is given to the OS manufacturer, less control to the user.

    I’ll be studying the tech sites closely before I touch a dam thing on my machine. Especially since companies like MS have admitted that not a single client has yet to be affected by either the Spectre or Meltdown vulnerabilities. There’s also supposedly a registry fix, but as usual MS doesn’t explain specifically what the registry fix effects.

    The big corporate computer tech industry is much like the MSM news industry — just as you have to go elsewhere for a broader news picture, the best info on computer tech likewise comes from the “alt-tech” sites.
