We present our fifth set of results from our mid-infrared imaging survey of Milky Way Giant H II (GH II) regions. Our analysis of DR7 and K3-50, utilizing multi-wavelength archival image data and FORCAST 20/25/37 micron observations, reveals the presence of likely massive young stellar objects (MYSOs) in both regions. The sub-regions in K3-50 indicate multiple star-forming events over time, while DR7 suggests more coeval star formation. The Lyman continuum photon rates in both regions are close to the GH II threshold, but uncertainties make their classification uncertain. K3-50 exhibits GHII-like properties, while DR7 resembles non-GH II regions we have studied. We will also provide an overview of the current status of our project and discuss the past, present, and anticipated results.
