Instance Method Summary collapse
- #detect_windows ⇒ Object
-
#read_wmic ⇒ Object
reads os name and version from wmic Thanks to Matt Wrock (github.com/mwrock) for this hint.
-
#read_wmic_cpu ⇒ Object
‘OSArchitecture` from `read_wmic` does not match a normal standard For example, `x86_64` shows as `64-bit`.
-
#windows_uuid ⇒ Object
This method scans the target os for a unique uuid to use.
- #windows_uuid_from_chef ⇒ Object
- #windows_uuid_from_machine_file ⇒ Object
- #windows_uuid_from_registry ⇒ Object
