  One-loop QCD corrections to the full gauge invariant set of electroweak
diagrams describing the charged current processes $e^+ e^- \to u \bar d \mu
\bar\nu_\mu$ (CC10), $e^+ e^- \to u \bar d e^- \bar\nu_e$ (CC20) and $e^+ e^-
\to u \bar d s \bar c$ (CC11) are computed. We compare the exact calculation
with a ``naive''approach to strong radiative corrections which has been widely
used in the literature and discuss the phenomenological relevance of QCD
corrections for NLC physics.
