Hello

Im a little bit confused should i first install KB #4078407 and then the following KB4090007 update?


Thanks

Just get the most recent one.

Yes, it's an optional update. Upgrading Windows gives you a new 'Software Distribution' folder. You will ALWAYS have to reapply the patch everytime there is a feature update. That's why the BIOS method is preferable, it works regardless of OS.

Yes, @winactive , what you said.

I just upgraded to 1803 and the mitigation is gone. Ist there an update for 1803?

Related to another thread I checked and double checked and NO, unfortunately 1803 does not load any Spectre mitigation MCU as yet.

Windows 10 April 2018 Update now available Monday, April 30

It is expected that MS will release a separate KB addressing this vulnerability just as they have done for previous W10 versions.
In a way it kind of scares how various KBs aren't compatible across the W10 platform as a whole.
Guess my brightest days halted at and around W7ish-like.

Cheers,

Straight away upgraded from 1709 > 1803, but haven't clean install yet.

My bad. The system I updated on Monday was only running v1709 and the KB4090007 worked.

I updated one of my own systems to v1803 and the KB4090007 isn't supported. Best get fixing with UBU if you can extract your BIOS image then all this goes away.

Ideally you'd want a BIOS/UEFI update. I can't seem to get UBU to play with my Fujitsu version of AMI UEFI version V5.x but it's a very interesting tool for sure.

Dell finally released micro code update for my Intel Corei3 Ivy Bridge desktop. Didn't get notice, just kept looking on Dell Support for BIOS update.

that's good. too bad Dell did not release a new microcode update for my "Sandy Bridge" desktop PC; I'm using a slightly older Dell computer than the one you're using.

Also KB4090007 is for v1709 only. those using v1803 will have to wait for a separate microcode patch starting next Tuesday May 8
