    As said before....you're in a great shape.
    The only thing that you might want to do is to enable BTIKernelImportOptimizationEnabled, because according to Intel your CPU cannot use Retpoline.
    To do that just make the two registry changes proposed in the Windows Kernel Internals blog post.
    @ddelo

    All done... Thanks again, I'll stop bugging you now. maybe.......

    Code:
    BTIHardwarePresent                  : True
    BTIWindowsSupportPresent            : True
    BTIWindowsSupportEnabled            : True
    BTIDisabledBySystemPolicy           : False
    BTIDisabledByNoHardwareSupport      : False

    L1TFInvalidPteBit                   : 45
    L1DFlushSupported                   : True
    P.S. - reran WinSat and got my mem score back up to 35400 from 33550, and a 9.3 and 9.1

    It's never a bother Dick. I'm glad it worked for you.
    Take care and don't give it a second thought if you need anything else.

    It looks absolutely fine!
    Maybe the only think missing, might be Retpoline mitigation.
    If you wish take a look at this post and follow the instructions in the Microsoft Windows Kernel Internals blog post to enable Retpoline and you'll be great.

    I'm having troubles with games on this one and 342, all "heavier ones like COD- WW3 and such are suddenly getting miserable FPS and hiccups despite benchmarks shoving respectable results and even most aggressive OC is not helping. Instead of 120-140 FPS, now getting 20-30 !!!
    I switched the SATA driver to Microsoft "Standard SATA/AHCI Controller" instead of Intel SATA and it fixed a similar issue.

    Huh? Retpoline increases speed/performance if you have Spectre/Meltdown enabled.

    The only downside is some old games don't run well, but that depends on if the patch is installed, by default Retpoline is not enabled.
    You need to edit reg like in this page.

    I see on the prior coulple pages, running some scripts etc to give what seems like important information regarding vulnerabilities/performance. Im wondering how to check this, and more importantly, if you can assist in interpreting?

    Part of the reason for my worry is that once I read through that thread, I saw it mentioned that if you had an "older" system, to check and see:

    "In other words, we established that, if not on the latest CPU microcode via a BIOS/UEFI update (as the manufacturers don't provide such updates for older PCs - it's their way of saying, get a new one!!!), then apply KB4465065 (in v1809) to get the most recent mitigations to all known, until today, vulnerabilities. "
    I went and checked and noticed I was on a build from 1803 in may! So I allowed it to download to 1809 just now. however, I dont see the update number mentioned above regarding microcode. Should I search it out manually and apply it?

    Another question, I have no clue how my updates could have been so delayed? When I looked in "installed updates" in programs and features, and it showed me maybe 8 updates total installed- I got this laptop in December of 2016! I dont forbid it to download under metered connections, and I also use DoNot Spy10 but I dont use that to block updates....confused. I would appreciate any way you can help set me straight. Some of this windows stuff is egyptian to me

    edit: got the script to run fine, here were the results. Seems in accordance with others? Dell laptop with intel i3 7200u CPU
