Example: Lenovo\\n\\nLeave empty to allow all manufacturers. A device from another manufacturer always fails, even when Behavior is set to Retry Execution Later, because the manufacturer never changes. Microsoft matches both Surface devices and Hyper-V virtual machines. Allowed values: `Lenovo`, `HP`, `Dell`, `Microsoft (Surface and Hyper-V)`, `Acer`, `ASUS`, `Fujitsu`, `Panasonic`, `Dynabook (Toshiba)`, `Samsung`, `VMware`.
