You cannot upgrade Hyper-V integration components or back up Windows virtual machines

This article describes an issue that occurs when you upgrade Microsoft Hyper-V integration components (integration services) of a Windows 8 or Windows Server 2012 virtual machine that has SR-IOV enabled, running on a Windows 8.1 or Windows Server 2012 R2 Hyper-V host. A hotfix or an update is available to resolve this issue. Before you install this hotfix or this update, check out the Prerequisites section.

Symptoms

Integration services setup always prompts for upgrade, even though the components are upgraded successfully for a Windows 8 or Windows Server 2012 virtual machine that has SR-IOV enabled. The Best Practice Analyzer (BPA) reports the integration services version as old or out-of-date.

Cause

This issue occurs because Hyper-V integration components services report the incorrect version during the integration components installation, even though all the components are upgraded successfully.
