Virtual Administrator’s April 2017 Patch Recommendations
Microsoft Fixes 45 Vulnerabilities with 644 patches this month
We have not uncovered any widespread problems with any of these patches and are releasing all of them. (AMD users read “Heads Up” below)
The top priority would be the zero day vulnerability exploited when a user opens a Word attachment (KB4014793). Next would be a vulnerability in Internet Explorer (KB4014661). Both of these are being actively exploited. Hyper-V and .NET are also priorities as well as the Adobe Flash update (KB4018483).
Microsoft’s summary of the April 2017 releases can be found here:
Details on top priorities
Security update for the Microsoft Office remote code execution vulnerability KB4014793 (CVE-2017-0199)
Cumulative security update for Internet Explorer KB4014661
Security update for Hyper-V Remote Code Execution Vulnerability Monthly Rollup/Security Only/Win10, KB3211308
(CVE-2017-0162, CVE-2017-0163, CVE-2017-0180, CVE-2017-0181)
.NET Remote Code Execution Vulnerability (CVE-2017-0160)
Security Update for Adobe Flash Player KB4018483
Microsoft has replaced the security bulletin ID numbers (e.g. MS17-XXX) with a new guide using vulnerability ID numbers and KB Article ID numbers. “The ”Security Updates Guide” (SUG) portal, the database’s content can be sorted and filtered by the affected software, the patch’s release date, its CVE (Common Vulnerabilities and Exposures) identifier, and the numerical label of the KB, or ‘knowledge base’ support document.”
This is actually a very useful database but without the familiar Security Bulletins it is difficult to gather concise information for this blog. The confusion appears to be universal. Depending on what you read there are 44 or 45 or 46 vulnerabilities. We will continue to work on improving the information we provide over the coming months.

The rollup patch for Windows 7,8 and Server 2008R2/2012R2 cause problems with AMD processors
Symptom: If the PC uses an AMD Carrizo DDR4 processor, installing this update will block downloading and installing future Windows updates.
Workaround/Resolution: Microsoft is working on a resolution and will provide an update in an upcoming release
These AMD machines will function normally outside of future update being blocked. Uninstalling the rollup will fix and we will provide additional guidance once Microsoft releases a fix.
