  • So when can we expect this to be resolved? Not updating isn't a solution.

     

    Hopefully this isn't like the last major windows 7 issue we ran into that took over a month for sophos to "resolve" https://community.sophos.com/kb/en-us/131685

    Hello Sammore,

    it looks - from the rather prompt reaction of Microsoft - like this is not an issue for which Sophos has to bear the undivided blame (or even the major part of it). Microsoft wouldn't block their patches if some other vendor has "self-inflicted" problems.

    To be a little fairer to Microsoft, I feel that both Microsoft and Sophos should be working closer together when OS changes such as the new patches are implemented. From what I have seen so far, if you are not running Sophos, Avast or Bit Defender then you were unaffected by problems with the updates that were released.

    The files that were patched, more specifically WININIT.dll and PRINTUI.dll, appear to have a new file signature. Had Sophos been made aware of these changes (If they weren't, I am speculating here) then I am sure their Dev team could have rolled an update out to account for these changes and prevent the problems being experienced.

    There is actually nothing wrong with the updates released by Microsoft. It's just simply a case that in order for them to work without issue, 3rd party vendors need to be aware of the changes and have patches in place for their products prior to release.

    I'm not interested in who bares the blame, I'm interested in a solution that resolves the issue at hand and helps us avoid these issues in the future.

     

    Right now we're at the mercy of Sophos to release a fix, whose track record in fixing these issues is slow to say the least.
