Hi Baiqing,
Thank you for your testing.

`qemu-ga.exe -s install -p \\.\Global\org.qemu.guest_agent.1' may help to
use virtio-serial ".1" in qemu-ga service. Otherwise ".0" is used by
default.

Is there any logs corresponding to the error in Event Viewer?
And this might be caused by unsupported VSS_VOLSNAP_ATTR_* flags in
SetContext()
called from qga_vss_fsfreeze_freeze() at qga/vss-win32-requester.cpp,
but I couldn't find out flags not supported on Windows 7 from VSS
references.
Could you try whether removing some of these flags is effective to avoid
the error in your environment?
Thanks,
Tomoki Sekiyama
