      I have a question in regards to a WSUS and the Meltdown/Spectre security update patches released by Microsoft.  It is understood that a specific registry key need be present in order to avoid blue-screens due to antivirus (in my case, Symantec EPP).  My question is – if I approve the security patches on the server, will the WSUS server be intelligent enough not to push the patch out to the clients that are lacking this key?  Or will it be pushed out regardless? 

      Furthermore, if it is pushed out regardless, will it fail installation if the key is missing?  Any input would be greatly appreciated.  I don’t want to cause BSODs to every PC on my network that hasn’t yet updated to the latest AV definitions (which we all know should be zero but this is real life).  Thanks!

      I am not behind a server. But I can tell you that lack of the Registry key on individual PCs keeps the update from being offered by WU, but does NOT prevent the manual installation of either the Security-only or Rollup on Win7/8.1 or the Cumulative update on Win10 1709. So you can set yourself up for a BSOD if your anti-virus (or other program that makes the call) is not compatible.

        Thanks for the quick reply.  Honestly, I am not too worried about manual installations – I doubt many of my users will try doing this on their own.  I am worried more about the updates that are being pushed from the server for automatic installation and how the client will handle the update.  It may be that we’re not really sure yet.

      From “There are multiple long threads on MS website saying SCCM and WSUS aren’t applying the patch without the AV reg key… oh boy, patching is going to stop for many orgs.”
