Numerous sources have reported that KB3161606<\/a>, an update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 (WS2012 R2), are breaking the upgrade of Hyper-V VM integration components. This has been confirmed & Microsoft is aware of the situation.<\/p>\n

As noted below by the many comments, Microsoft eventually released a superseding update to resolve these issues<\/a>.<\/em><\/p>\n

The scenario is:<\/p>\n

    \n
  1. You deploy the update to your hosts – which upgrades the ISO for the Hyper-V ICs<\/li>\n
  2. You deploy the update to your VMs because it contains many Windows updates, not just the ICs.<\/li>\n
  3. You attempt to upgrade the ICs in your VMs to stay current. The upgrade will fail.<\/li>\n<\/ol>\n

    Note that if you upgrade the ICs before deploying the update rollup inside of the VM, then the upgrade works.<\/p>\n

    My advice is the same as it has been for a while now. If you have the means to manage updates, then do not approve them for 2 months (I used to say 1 month, but System Center Service Manager decided to cause havoc a little while ago). Let someone else be the tester that gets burned and fired.<\/p>\n

    Here\u2019s hoping that Microsoft re-releases the update in a way that doesn\u2019t require uninstalls. Those who have done the deployment already in their VMs won\u2019t want another painful maintenance window that requires uninstall-reboot-install-reboot across all of their VMs.<\/p>\n

    EDIT (6\/7\/2016)<\/p>\n

    Microsoft is working on a fix for the Hyper-V IC issue. After multiple reports of issues on scale-out file servers (SOFS), it’s become clear that you should not install\u00a0KB3161606<\/a>\u00a0on SOFS clusters either.<\/p>\n
