This article provides a mirrored download to the Hyper-V Integration Services ISO for Windows NT 10.0 and newer.
Microsoft Windows 10 and Microsoft Windows Server 2016 no longer include the Hyper-V Integration Services ISO, vmguest.iso. The rationale behind this change is that the latest supported Windows and Linux operating systems provide their own Hyper-V integration.
This means that there is no built-in way to install Hyper-V Integration Services into legacy operating systems such as Windows XP (Windows Embedded POSReady 2009).
Fortunately, there is a direct download link mirror to the Hyper-V Integration Services 6.3.9300.16384 ISO, which came from Windows 8.1 / Windows Server 2012 R2. You can download this file and mount it as a CD in your legacy Hyper-V guest to install Hyper-V Integration Services.
