Not getting today's important 64-bit W7 updates in 2018 so far.

No****, Sherlock ! Happened to my Win x86 box, which resulted in a 'Start up repair' that brought it back to life. Then Windows Update offered the February 'Quality' Rollup, which installed fine. AskWoody has a thread on the issues with KB4088875 but I can't access it due to a 'Gateway failure' which, I'm assuming, is being caused by too many web site visitors. A Googley search shows MS has stopped pushing the patch via WU and will most likely pull it, quietly. Like a 'one cheek sneak'. https://www.computerworld.com/articl...anking-it.html https://www.askwoody.com/2018/buggy-...rom-microsoft/ Hold off on that patch as it's still showing in the WU Catalog. It bit me, don't let it byte you. Looking at KB4088875, I decided not to get it as I don't have Internet Explorer - not even the .exe on the disk I installed KB4088878 yesterday and it seems to be OK. Apparently it can break networky-thingys but I don't have those. According to InSpectre I'm now patched against Meltdown but not against Spectre. The microcode is out for Broadwell but still not on Gigabyte's site. You don't have to wait for a BIOS flash update. The OS can install one for you, after OS bootup. Right now this says Windows 10, so in a Windows 7 group, we can stop reading right here. https://support.microsoft.com/en-ca/...rocode-updates Skylake, Kaby Lake, Coffee Lake (no broadwell, haswell, ivy bridge quite yet) Those are *not* being put in Windows Update. They're for private consumption. Like moonshine. The microcode loader in Windows has *always* been loading one of those, but at the current time, it's using out of date versions. Because this particular patch could be performance-affecting, they're not being forced on people. ******* Using Linux, you can learn where the master file is located. At the moment, Linux is using the older monolithic release mechanism, where the master Intel file with a couple hundred processors in it is loaded via the microcode loader. https://wiki.archlinux.org/index.php/microcode https://downloadcenter.intel.com/download/27591?v=t https://downloadmirror.intel.com/275...e-20180312.tgz As Windows users, we don't want the whole file. We want the README :-) The releasenote tells us what has changed since the last (stable) release November 17 of last year. Presumably Microsoft has been running November 17 versions on all our computers (via Windows Update) since last year. November 17 covers any hardware bugs in CPUs, but has no Meltdown/Spectre coverage.

RELEASENOTE(pulled).txt from microcode-20180108.tgz file -- Updates upon 20171117 release -- IVT C0 (06-3e-04:ed) 428-42a === my processor SKL-U/Y D0 (06-4e-03:c0) ba-c2 BDW-U/Y E/F (06-3d-04:c0) 25-28 HSW-ULT Cx/Dx (06-45-01:72) 20-21 Crystalwell Cx (06-46-01:32) 17-18 BDW-H E/G (06-47-01:22) 17-1b HSX-EX E0 (06-3f-04:80) 0f-10 SKL-H/S R0 (06-5e-03:36) ba-c2 HSW Cx/Dx (06-3c-03:32) 22-23 HSX C0 (06-3f-02:6f) 3a-3b BDX-DE V0/V1 (06-56-02:10) 0f-14 BDX-DE V2 (06-56-03:10) 700000d-7000011 KBL-U/Y H0 (06-8e-09:c0) 62-80 KBL Y0 / CFL D0 (06-8e-0a:c0) 70-80 KBL-H/S B0 (06-9e-09:2a) 5e-80 CFL U0 (06-9e-0a:22) 70-80 CFL B0 (06-9e-0b:02) 72-80 SKX H0 (06-55-04:b7) 2000035-200003c GLK B0 (06-7a-01:01) 1e-22 And I observed in January, using a recent enough Ubuntu distro, my processor go from 428-42a and applying the March 12 one as well, the progression would be 428-41a-42c. So you can see the version number continues to be bumped. My BIOS loads 416 on my processor. In Windows I would see 428. In Linux in the middle of January, it read out as 42a. In March in Linux, it went back to 428 (Linux pulled the bad one). If I were to do some Linux experiments in the next few weeks, the Linux one would go to 42c. If you have a Pentium 4 processor, their release number hasn't moved since 20171117 and if you checked the microcode in either file, it's probably the same as a file from 2015. The newer processors are getting patched first. And they will work their way back. However, some of the patched processors, will have absolutely no delivery mechanism. (Motherboard company won't do it, Microsoft won't provide patch for all OSes.) So now, even though Windows users can "smell and touch" the bytes of the updated Microcode, the download file on the Windows side ("tested") is still "Skylake, Kaby Lake, Coffee Lake". Microsoft is taking their time. Microsoft is making this an optional download for people who need the "assurance" of Spectre protection in hardware via Microcode, to do it from the OS level. If your motherboard maker releases Broadwell before Microsoft does, then sure, you can do it via a BIOS update. For my Pentium 4 machine, no, no BIOS update will ever be offered, so that Microsoft download page would be my only option. And since right now, only Windows 10 gets the microcode (on that page at the moment), my Pentium 4 is surely... out of luck. Only the last model or so of Pentium 4 is Windows 10 compatible. Practically nobody owns one of those :-) Now, even if you bodge that Microcode into an OS, can the OS even use it ? Intel was proposing some silly knobs to twiddle with respect to that Microcode, and even if you hack the file into your OS, the OS won't really use it unless say, the kernel is modified to use it or something. There are more details involved than just "delivery", there are also "usage" issues. And we don't know since the squabble between Linus Torvalds and Intel, whether Intel budged on their control mechanism for enabling protection. For everyone else, go back to updating your Facebook page now. Nothing to see... Move along... Move along. At the current time, only around 200 test samples of malware from Black Hats have been spotted via Virustotal. The Black Hats are still working on their Meltdown/Spectre code and have not perfected really good exploits as of yet. If you use a really up-to-date browser, you have already received some "timing attack protection" in Javascript arrays or so. "Ad hoc protection", is how Pentium 4 owners running Vista will get their protection. I'm personally going to feel "warm and fuzzy", right up until the day the Black Hats tip over my machine :-) At that point, I won't be able to update my Facebook page. Paul |

I'll admit to not understanding most of them (I tinker on the edges - oil up to the knuckles, not elbows). I might just have to contact Gigabyte if nothing appears. -- Peter.
