Those are one
Microsoft ACPI-Compliant System driver and rest of them
Virtual Machine Bus drivers, they need no drivers and can (should) remain marked with a question mark or exclamation point in Hyper-V virtual machine's Device Manager.
The
Microsoft ACPI-Compliant System driver (highlighted yellow) is just a virtual device checking the generation of the vm (Windows 7 guest can only be Gen. 1):
The
Virtual Machine Bus drivers are taking care of communications between the guest and host. All these drivers are marked with a question mark or exclamation point because the devices themselves are on host, not in guest and the vm is a bit "confused" about this
.
Those drivers should not be updated, just ignore them.
