Taylor Brown: I have gotten a ton of questions about the KVP Exchange or Data Exchange Integration Component So what is it and how do I use it? The KVP Integration component allows the guest and host to query and provide information to each via pairs of Keys and Values. The KVP integration component provides some basic Keys and Values for you, I talked about the host accessible ones in a previous post Hyper-V WMI Using PowerShell Scripts Part 3 (KVP's - Guest OS Version) these include things like the fully qualified name, OS version, Processor Architecture etc There are also some guest accessible values that provide some information on the parent (host) such as HostName, PhysicalHostName, PhysicalHostNameFullyQualified, and VirtualMachineName. These values are located in registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Virtual Machine\Guest\Parameters. The other thing you can do via the KVP is write registry keys from the parent (host) and read guest provided registry keys from the parent (host). Today I am going to show how to write keys from the parent into the guest.
