Microsoft KB4013429 breaks Hyper-V 2016 Backup

KB ID: 2262
Product: Veeam Backup & Replication
Version: 9.x
Last Modified: 2017-03-21


After installing Microsoft KB4013429 update on a Hyper-V host, Hyper-V backups may fail. Removing the update may cause the host to enter a BSOD loop.


The problem appears only if KB4013429 update is installed not on all nodes of a Hyper-V cluster.
In more detail, the issue persists if the following conditions are met:

  • Cluster resource owner node is not upgraded
  • VM owner node is upgraded


If you are about to install KB4013429 update, consider maintaining consistency of the update installations across your Hyper-V cluster.
