Don't let Microsoft mess up your mostly already protected computer with the Intel aimed Meltdown Patch already released. If you've already become a victim of Microsoft's patch, aimed at Intel CPU's, then check this page to recover.
Microsoft has reports of customers with some AMD devices getting into an unbootable state after installing recent Windows operating system security updates. After investigating, Microsoft has determined that some AMD chipsets do not conform to the documentation previously provided to Microsoft to develop the Windows operating system mitigations to protect against the chipset vulnerabilities known as Spectre and Meltdown. To prevent AMD customers from getting into an unbootable state, Microsoft will temporarily pause sending the following Windows operating system updates to devices with impacted AMD processors at this time:
