Microsoft stops fixing security flaw on PCs with AMD chips

The update was actually supposed to address Meltdown, a hardware vulnerability affecting Intel x86 and ARM chipsets. The problem primarily threatens devices running on processors from AMD's larger rival, Intel, but also could cause trouble on devices running on other chips.

Microsoft has begun issuing Meltdown and Spectre fixes in its cumulative Windows update, but some owners of computers with AMD Athlon 64 X2 CPUs started complaining that the update made their machines unbootable. "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". It is installed automatically through Windows Update. The fix should work on both Windows 10 and 7 devices.

Microsoft also said that security updates froze some computers using chipsets from Intel rival AMD, dragging AMD's shares down almost 4 percent. It's worth noting that the fix basically removes the patch and Windows restores to the normal state.

"After several failed boots it do roll-back then it shows error 0x800f0845".

"For our customers' protection, Apple doesn't disclose, discuss, or confirm security issues until an investigation has occurred and patches or releases are available", the company said on its website.

To help prevent stop errors that are caused by incompatible antivirus applications, Microsoft is only offering the Windows security updates that were released on January 3, 2018, to devices that are running antivirus software that is from partners who have confirmed that their software is compatible with the January 2018 Windows operating system security update.
