Microsoft today released a bunch of new updates - for all Windows Builds. The March 2018 Patchday is as expected and there this time no surprises. As always you can download and install the latest updates manually via the MS update catalog or via WUS.
Microsoft has updated its own Security Advisory ADV180002 Guidance to mitigate speculative execution side-channel vulnerabilities.
KB4088876 (Spectre and Meltdown)
This update provides cumulative Spectre and Meltdown protections for 32-Bit (x86) and 64-Bit (x64) versions of Windows except the KB4078130 update that was offered to disable mitigation against Spectre Variant 2, however this doesn’t mean that these are microcode updates because Microsoft not integrates those things in security or rollup related patches.
All downloads are also available via WUS right now or are been rolled out during the next hours.
Windows 8.1 and Windows Server 2012 R2
Windows 7 SP1 & Windows Server 2008 R2 SP
Realtek HD Audio v126.96.36.19993 WHQL for Win 7 - Win 10
Adobe Flash Player Update
The following issue are known for Windows 7 and Windows 8.1. Windows 10 has no known issue this time (the error 0x80070643 is by itself not really related the update, so I won’t see it as issue but I list it because MS does).
This Patchday is so far without any reports which means you can go ahead and install the updates without been worried about consequences.
I found nothing which had a negative impact on my test machines. Surprisingly the ‘dead’ Office 2007 got updates even if it’s end of life.
