The AMD-compatible Spectre fix for Windows 10 is now live and being distributed through Windows Update.
When the Meltdown/Spectre vulnerabilities first surfaced, Microsoft was quick to respond by rolling out software mitigations in its operating systems. Unfortunately, the fixes in Windows 10 had an unintended consequence for some older AMD CPUs, making them unbootable. Microsoft stopped issuing the update to affected AMD systems, but already affected users (opens in new tab) either had to use System Restore or reinstall their OS.
The issue was technically officially fixed on January 19 (opens in new tab) and Windows patches with the fix were manually downloadable on Microsoft Update Catalog (opens in new tab), but manually updating is only recommended if you have an urgent need and know your current Windows build. For everyone else, Microsoft has just made the fix live on Windows Update with Windows 10 Build 16299.214 (opens in new tab). Like all patches delivered through Windows Update, users will get them automatically or by clicking “Check for updates” in Windows Update.
Users should note that this update only applies to older AMD CPUs. Ryzen and Threadripper-based systems weren’t gated from receiving the original patch. Also, this patch has no relation to the recently announced optional Windows patch that disables Spectre Variant 2 fixes for Intel CPUs. If you’re on an AMD system, then you should be glad that you’re, at least, not stuck with a randomly rebooting system.
Meltdown was the only one that affected Intel and not AMD. Everyone knew that after the first 2-3 days the exploit was announced. It was a big deal because meltdown was really easy to implement, whereas Spectre was much harder.
interesting to see if this has any effect on the speed of older amd CPUs...
Of course we won't be able to test that until Intel can put together some patches and microcode that don't make Intel systems unstable.
As far as things go these days concerning people that take it upon themselves to divulge information about things better left unsaid..you see it everyday all across the board...sad really.
And just bought new CPU ... first time Intel ... i5 8400 ... so kinda sweatingg the details.
