I ran the tool for the Intel firmware update last week and got the same result - was a bit confused at the time when it said my machine was not vulnerable but that makes sense now.

Hopefully the various software patches, both for OS and browsers plus continuing vigilance and sensible internet use will be enough to stay protected from future exploits. I'm not in a position to update my laptop at the moment so that will have to be good enough.

I'm having the same issue with work PCs from HP and Dell which likely won't get firmware updates either as many are 4th or 5th gen Intel and there's no budget to replace them for a couple of years. Talking to the desktop support guys there's a lot of misunderstanding over the details but fortunately the systems people I talk to do know their stuff. Very much like the discussions on other flight sim forums compared to here, particularly with regard to performance impacts. WinkLOL

Microsoft is hilarious...   naaa  it wont hurt Windows 10 and newer processors, just Windows past and Haswell, exactly the opposite of what I have seen thus far  Wacko Sell that OS~!
 
 
 
oh, yes and by the way, sys admins might not want to patch up and take the risks over the perf hit   LOL

I have updated my MSI Notebook running Windows 10 with the OS patch KB4056892 and confirmed it was installed with Powershell, using this link as reference:
 
(Scroll down to "How to check if your PC is protected against CPU vulnerabilities")
 
 
I have also done compare runs with 3DMark06 before and after the OS patch and after updating NVIDIA drivers with no defined change in the final performance. Maybe because of insufficient number of runs or specific hardware reasons. Total of 10 runs, four before the OS Patch, three after the OS Patch and three after updating NVIDIA drivers. These runs were all made with the i7 6700HQ (HT turned off), GTX960M, 1x8GB DDR4 2133-15-15-15.
 
The average score with this hardware is about 22660 points both before and after all the updates.  A slight drop of about 150 points in the average score was noticed with the OS patches, which then climbed back to the original average score after the NVIDIA driver change.

While waiting for MSI to release firmware for the Spectre flaw, I updated the BIOS and the Intel ME Firmware to fix the sequrity vulnerabilities of Intel SA-00086.
 
MSI provides a convenient Intel ME Update Tool to patch the security vulnerabilities (Intel SA-00086).
 
 
Imagine the time spent to fix issues like this by people all over the world.

My tests were to compare W10 and to W7 before and after the patches.
 
Although I did point out the drop in W10 directly (not compared to W7) was only around 300pts on this end, nothing significant. But I defiantly show a 1700pt difference between W7 and W10, 14-1500 of that right out of the gate and much smaller change when driver was applied.

I have moved all of my sensitive work over to my laptop, but is there a way of wiping the sensitive information stored in the memory of a computer which is unable to get the updates needed to sort out the flaw?
