      Just need some clarification

      We installed KB4099950 in April of 2018. We see in the pciclearstalecache.txt file where the appropriate registry keys were successfully deleted.

      It our understanding that since we installed KB4099950, we don’t need the recent pciclearstalecache exe.

      Do we need to run pciclearstalecache again now (May 2019) or is this just a catch up for those who didn’t run it last year?

      Please see the procedure here.
      You do not execute pciclearstalecache directly.
      If it is present with the SO, and is required, it will be executed automatically as part of the SO installation.

      Further information: pciclearstalecache was bundled with the Monthly Rollups previously and worked as described in the above procedure. This is the first time that I know of that it has been bundled with the Secutity-only Updates.

      Administrators should ensure that any one or more of the Monthly rollups released between April 10, 2018 (KB4093118) and March 12, 2019 (KB4489878) have been installed prior to installing April 2019 and later updates. Each of these rollup updates includes PciClearStaleCache.exe.

      my bolding, applicable to patches via Windows Update.

      There has always been an amount of confusion regarding pciclearstalecache We have looked back at our documentation from April 2019 and note that Security Only patch KB4088878 re-released on April 17, 2018 notes “This issue (NIC problems, etc.) is resolved by KB4099950 which will be automatically applied when installing this update (KB4088878)”. (Words in parens are mine). Interestingly, Microsoft has removed this language from the textual description of KB4088878. (What I’m citing is from a printout from April 2017). Note that we installed the post April 17, 2018 version of KB4088878 per Microsoft’s recommendation.

      In April or 2018, a pciclearstalecache.txt file was created after we ran the KB4088878 msu file the PCI SlotPersistentInfo registry keys were successfully deleted indicating that pclclearstalecache ran (the txt file wasn’t there before we installed KB4088878.

      So, to PK, thanks again. I think we are good as far as I can tell. We’ve had no issues with NICs so we’ll leave well enough alone at this point.

      These symptoms are especially common on guest virtual machines and on machines which have not been updated since March, 2018.

      Correction to the first sentence in my last post above, should read “documentation from APRIL 2018…”.

      “There has always been an amount of confusion regarding pciclearstalecache We have looked back at our documentation from “APRIL 2018” and note that Security Only patch KB4088878 re-released on April 17, 2018… Correction is in quotes above.

      There were a lot of posts regarding this issue from a year ago. Seems like it is still floating around.

      latest version of the pciclearstalecache.exe file is 6.1.7601.24197 as I checked the version details on that EXE file myself.
