Wow. This is extreme. Anyone working at microsoft over the age of 5?

Intel inside, unfortunately, has a whole new meaning these days.

Very bad form indeed, lets hope they get it sorted out in short order.

Apparently the issue is an incompatibility with the BIOS microcode and the UEFI/OS microcode...inferring a BIOS update is needed.

I'm just laughing at one of the replies there about how this is normal for Spectre mitigation :P

I find this funny, as I stopped and disabled updating Windows 10 in early 2017, as well as disabling all the spy stuff using O&O Shutup.
1.5 years later, I'm still here ! My computer hasn't exploded, it's not swarming with viruses, it works as fast as it ever did, and having 2-3 months of uptime at a time.
Basically, it was rebooted about 10 times total in last two years.
So much fuss about these "vulnerabilities". They mean NOTHING AT ALL for the knowledgeable home user. (Yes, mitigation is important and critical for datacenters and virtualized environments where you don't know who runs what, but for single person just reading news, playing games and the occasional music... it means nothing)
And now this ;-)
Giggly giggity.
Note: I use an overclocked BW-e 6800K @ 4.1 Ghz all 6 cores (it can do 4.3 but gets too hot so keeping it down and low voltage)

The fix necessary will require the bios to have latest MCU.
Not a big deal if you want to do it yourself.

It surely is unpleasant. But it is not like there are many people with Broadwell-E who bought system overclocked from shop and have no clue how to OC or deal with patch.
I think most who have it OCed did it themselves and are capable to look on internet moment they face this problem.
If it was wide spread issue affecting regular desktop CPUs, it would be problem as there many shops which sell pre-overclocked chips in complete systems and users are not exactly technically equipped.
Many would not even realize that it is CPU misbehaving.
This just raises eyebrow or two.
BLEH!
Crap...

Well now, this is some crap....

This update isn't just affecting Intel systems. MS is also pushing it out to AMD based systems. Apparently, they screwed up. I have this microcode update installed and I'm running a Ryzen 5 1600....

Uninstalled, blocked it, all good..

Doesn't matter if it is supposed to affect it or not. It should have never been downloaded in the first place.
