You know- you could get some useful responses _if_ you could tell a
story. Quick, simple, cogent would work for somebody who's not there.
Not trying to be cute here, but you should consider the plight of the
reader.
Like: where is the insulation? Where is the moisture? Fifteen words or
less, each, for a clear word-picture. How cold is it (in deg F,
please)? What kind of windows? Describe the insulation and inner wall
surface, please. The "back right (sic) hand corner" is oriented where
on the compass?

Concrete has lousy R-value. Exposure to wind and lack of southern
exposure can markedly reduce its temp at an outside surface. It sounds
like you've got some insulation on some of the basement wall. Consider
going from floor to top of rim joist with as much as can be fit, with
some sort of inside covering, like maybe sheetrock for fire-safety.

Assuming there's no leak from the outside, since you're certain it's
condensation.
