The Microsoft Spectre + Meltdown Patch Schedule Rev. 2.0

Spread the love

Ever since the Meltdown and Spectre exploits were exposed, Microsoft has been working overtime to patch Windows against them. Unfortunately, they were quite secretive about their Spectre and Meltdown patch list and schedule. We usually only find out when something bad happens, like when some patches bricked AMD systems.

They changed that stance recently, quietly releasing their Windows Spectre and Meltdown patch schedule. This schedule listed the patches they have released so far, or are about to release. For your convenience, we have divided and sorted them according to the applicable Windows version.

The Microsoft Spectre + Meltdown Patch Schedule

Please note that the current Microsoft Spectre and Meltdown patch schedule covers the January and February 2018. We will update the schedule as and when Microsoft releases them.
