Is "Windowed Fourier Transform" a synonym for "STFT"?
In Chapter 2.4 Previous Work of  The Short Time Fourier Transform and Local Signals, S. Okamura, 2011, one reads:


  The STFT is also known under many names such as the windowed Fourier
  Transform, the Gabor transform, and the local Fourier transform.


Later, one discovers that the definition may  slightly vary with different authors, but, at first glance, they are the same. Be careful though. For some persons, a "Windowed Fourier Transform" is a mere Fourier transform of  a windowed signal. Because there is no sliding nor shift involved. For some, "short" implies "finite support".

Leaving theses versions aside, my personal interpretation and use  is that a “Windowed Fourier Transform” is a special case of a slightly more generic  “STFT” acceptation, for two (mild) reasons:


"windowed" somehow conveys the idea that only one window is used. But you can easily use different windows for STFT, long ones for low frequency, shorter ones for high frequencies.
the concept behind  "what a window is"  is not evident. However, for most people, a window  often has a non-zero sum (or unit), and often is either increasing/decreasing (unimodal, flat being a trivial version) or monotonic (like exponential window or weighting) for causal implementations. For short-term, it only needs to be "short", or well-concentrated in time, and could be more complicated.
