    PowerShell script to Check if Your PC Is Protected Meltdown /Spectre


    https://www.howtogeek.com/338801/how...n-and-spectre/

    Curious if anyone has run this particular script having followed the directions in the article. I am modestly comfortable running PowerShell but the instructions seemed to get deep into the weeds for me and I aborted. I installed a bios update a couple of weeks ago (BIOS Version/Date LENOVO N1UET43W (1.17 ), 12/13/2017) though I do not know if it was made available because of the Meltdown and Spectre debacle. No other updates from either Intel or the manufacturer has been pushed yet though I believe my AV according to the Bitdefender website has pushed a particular registry key that is needed. I have not installed Dec or Jan cum. rollups. TIA.

    I saw that and got confused. I saw Microsoft's equivalent posting which didn't give enough detail. Then I found Find out if your Windows PC is affected by Meltdown/Spectre vulnerabilities - gHacks Tech News I was able to follow it so it must be pretty straightforward. The end result: two PCs need a BIOS upgrade and are old enough that no such upgrade will be forthcoming. I haven't been brave enough check our laptop. It's new enough that a BIOS update might be available.

    Hello, :)

    It's for the NuGet PowerShell script from Microsoft below.

    Verifying protections are enabled

    To help customers confirm whether protections have been enabled, Microsoft has published a PowerShell script that customers can run on their systems. Install and run the script by running the following commands:

    Brink, I think the problem the OP was referring to was not the purpose of the script but rather the instructions provided at howtogeek. They gave a few helpful comments that were missing in the Microsoft instructions but made the installation process seem needlessly involved. It's actually quite simple.

    Yeah, I prefer the commands at the link I posted instead. Much simpler.

    That's right. I was hoping for a mostly one and done PowerShell execution but the steps seemed to go on and on. Thanks to all who responded. I will check out the alternative solutions tonight.

    There is an exe posted for the script somewhere... (if that's what's needed)

    However, as I have said before... there is a right way and a wrong way... there is method in the madness...

    On another matter I was met with a slew of google alerts this morning about the slow down caused by the patch. I have not read the articles yet nor have I applied the patch and in fact the articles might just be a re hash of old news but I am wondering what the general consensus (experience) might be regarding the slow down. As someone who just this past Black Friday purchased a notebook from this century a Lenovo P51 which is quite speedy I was dismayed reading about the bottleneck that the patch may cause though it would seem I have plenty of company. Last computer I had which BTW I am writing from now is a Compaq Presario CQ60-615DX 2.2GHz Intel Celeron processor 900.

    AFAIK only SSD write speed takes a hit...and only with the firmware 'mitigation codes'... (the Win update on it's own is dormant without that) I doubt you will even notice it tho' - lot's of click-bait stupidity out there - pay no attention. We know everything at TF. :)
