So what the hell is this microcode? isn't it a sort of firmware? That means it gets updated at every boot or simply that it can be rolled back? We are talking of updating not a piece of windows but a piece of intel software inside the CPU, right?
CPU microcode is applied by the BIOS of the motherboard or it can be applied by Windows too. If applied by Windows then that overrides any code that the BIOS might contain. Yes, so microcode updates are issued either by motherboard manufacturers in the form of BIOS updates or they're offered by Microsoft through Windows. There are other ways to apply microcode, I remember one time I did it using some kind of Linux driver (I think), but I've forgotten the details of that...but that's by-the-by and not what you were asking.

Will this be included in the cummulative update too ? So every user will get it ? I hope yes 🙂 Also, is there a chance that it might increase performance a little bit ? (or at least don't degredate it, since it's a newer patch)

Microcode is more technical then a CPU driver, but not as low level as a Bios update? I guess the reason for it not being put in Cummulative could be because it could fuck up non Intel CPUes or maybe even future Intel CPUes. The reason for it not being a bios update could be because motherboard manufacturers simply no longer support the board, so a bios would never be released anyway.

I think win10 would be bug free if ms dropped intel CPU support!

I don't think so.

Correct. It's "volatile firmware", so to speak. Wikipedia to the rescue! https://en.wikipedia.org/wiki/Intel_Microcode

No Windows 8.1 love? Microsoft being Microsoft. I can totally understand no more support for 7, but 8.1 is not EOL. Or am I missing something?
that will come soon, they want people off win7/8/8.1 and they are not beyond doing "certain" things to get people to get on windows 10, as much as I have issue with windows 10 I would never want to go back win7 and I still would never use 8/8.1. Lots of microcodes being released since first flaw announced to public, I have no seen so many microcodes release in all my year making pc's atlest not microcodes actual known publicly How much hit do these supposedly do? not that I seen performance hit with the initial microcode updates

you can just remove windows update if microcode cause issue. microcodes update via Bios are one that not removable or alot harder to roll back

I disabled it on my Sandy E and Westmere E, im not giving away my performance and HT, im not someone who would benefit from exploiting so who cares.
You are more likely to be attacked by those issues--MDS and L1TF and almost all those Spectre variants can penetrate virtual machines. Virus can be excused and gain root privilege from within your browser. Giving up performance is a must if you actually want to use the computer with an Intel CPU.

Or just go with an amd cpu and stop thinking about it.
Im already on it....finished work early so just about to switch to my new Asus prime x570pro and new 3800x, hopefully i wont lose to much performance.

One thing I'm finding a little weird is how there's not much mention at all about the Intel GPU vulnerabilities in Windows. Perhaps there aren't any, but I find it weird how that could be OS-specific. The mitigations resulted in a devastating performance blow in Linux, but, I'm not sure if it was a Linux-only problem. Intel has recently released another patch that fixes most of that performance loss, though I don't yet know how bad it currently stands.
I'd assume most people on these kind of sites don't use Intel IGPs since they're playing modern games. It's the same deal for very few remarks about Intel's driver support for older series, compared to alot more complaints when AMD or Nvidia stop their support. I have seen the Intel IGP issue mentioned on some forums but I also think it didn't get much attention because it wasn't a final fix. There'd probably be more headlines if the new Windows driver does have the same hit though.

No difference to me, but you can go to amd and do lower fps anyway kkkkk
Sure. Here is another one. Performance per $. Performance per Watt. But hey, we are enthusiasts and supposed to pay $400+ for "Gaming" CPU. And who cares about Watts these days anyway, right? Day AMD became competitive in those metrics, they stopped being important. - - - - Come and tell me what new unused Ryzen 7 2700X costs. Then find intel's price equivalent CPU for which you'll be able to buy completely new, unused MB in 2 years in case your board dies. And tell me what bonuses you get on intel's side at that price point. Because even today, AMD gives Borderlands 3 + Outer Worlds + 3 months XBox pass. - - - - Too hard? Then take it from other side. Take Ryzen 7 2700X and find intel's performance equivalent that will be still supported in 2 years. And compare prices and what bonuses you get included in that price. - - - - No? Too ugly difference? Then you'll have to admit, that in situation where "apples to apples" means equivalent price point, AMD's CPU is better for most of the market.

2700x? Cmon, these cpu loses today to i7 4790k with half of threads, you make me laugh, who buyed one have better performance than yours today but since 3 years before Btw, you doing a wrong comparison, between one cpu released 3 years later with less performance and saying its better because cost less, sure, if i compares ryzen 3600x against 1800x i will think the same, its a very stupid comparison

Typical the day I switch to my new AMD system is the day MS fix the security issues with my old Intel one....

People with AMD CPUs do not worry - researchers will find vulnerabilities in there too. I am sure that AMD escaped a couple of latest vulnerabilities not because they were clever but because they were lucky.

BIOS microcode update load the updated microcode at BIOS boot, OS microcode update load the updated microcode a OS startup.

So they are lucky because they not implemented the same features as Intel did or they are lucky because they were so stupid to not implement the same features as Intel did? Or is just a big conspiracy of the researchers because nobody cares about them? Or is just your comment ...

so 0x27 for mine? I already have this hard bios patched though. 😀 //note; will post after if there is any difference in those codes. EDIT: no all the same.

Is it possible that this update could brick a cpu or motherboard?
