MSFT0101 is the related to core power and performance counters. It allows the guest OS to request specific power states from the hypervisor. Because it's a synthetic device, the driver is typically included in Integration Services (for Hyper-V) or VMware Tools (for VMware).

You either haven't installed the guest integration tools, or you are using a VM platform that doesn't provide a specific driver for that synthetic ACPI table. Scenario B: The "Connected Standby" / Modern Standby Artifact On physical hardware, specifically on tablets, convertibles, and ultra-low-power laptops (Intel Atom, Core M, or ARM-based devices like the Surface Pro X), this device appears as part of Modern Standby (formerly Connected Standby).
