The "QEMU Guest Agent VSS Provider" service is running successfully.

It worked on Windows 10 RS1 (before the upgrade).

Installed from virtio-win-0.1.126_amd64
which was built from master branch with latest commit (8aaf403) - https://github.com/virtio-win/kvm-guest-drivers-windows 

Windows version (upgraded from RS1):

Evaluation copy. Build 15019.rs_prerelease.170121-1513

Not a bug!

I have forgotten to add the socket in the start script :(
