Q. How can I check which version of Integration Services a virtual machine (VM) is running?

A. You can check the version of the Integration Services through the Device Manager GUI or via the command line. You actually check the Virtual Machine Bus driver’s version because it’s one of the key parts of Integration Services and its version reflects that of Integration Services.

To check the version of Integration Services in Device Manager, expand System Devices, right click Virtual Machine Bus, and select Properties. Click the Driver tab and the Driver Version line will show you the version you’re running, as shown here:

To check the driver version from the command line via Windows Management Instrumentation, use the command wmic as shown here:

C:\Users\john>wmic datafile where name="c:\\windows\\system32\\drivers\\vmbus.sys" get version

When checking the driver version of the Virtual Machine Bus, values you may see and what they mean include:

· Beta 1 - 6.0.6001.18000
· Release Candidate 0 - 6.0.6001.18004
· Release Candidate 1 - 6.0.6001.18010
· Release to Manufacturing (RTM) - 6.0.6001.18016
· Post release to manufacturing - 6.0.6001.18017 or above

My VMs have a version number of 6.0.6001.22261, as you can see in the examples, because I have applied a number of Hyper-V updates
