I think hotplug is a better method for adding memory for Windows.

For Windows, I believe you would need to emulate actual hotplug of
memory like a physical machine, using ACPI. It's only supported on
Enterprise versions of Windows too.

In 99.9% yes because it is normal way of configuring devices in Windows.
However, to take final decision I must read some docs and do some tests.
