Hi!

KB4100480 is for Total Meltdown, NOT Meltdown /Specter.

Total Meltdown is introduced by Microsoft, Meltdown /Specter are the CPU bugs tested by the InSpecter tool.

If Linux is protected and Windows is vulnerable, would it not be safe to run Linux as your host OS, and run Windows in a VM inside of the Linux host? Doing this would prevent Windows from interacting directly with the machine’s hardware, which should protect from any of this type of Windows vulnerabilities.

Er, the CPU is running all of this, so, it would still be exploitable? Or could one OS update the CPU microcode for all OSes?

The way I understand virtualization, one guest OS cannot pass code to another OS, but the hinge point is the CPU, which is vulnerable here..?

The “good” news is that you can uninstall KB4023057 from the “Uninstall a program” section of the Control Panel. It’s in two parts. Once uninstalled, Windows Update will fetch the newest “fixed” one.

Cynical note: Woody, Amazon ads on this page are all for SP… You might want to look at that!

Keep up the great work!
