I don't read "other windows generated at startup" as necessarily meaning error messages, and so long as those windows can be minimized you'll eventually find it.
I'd probably go the clean boot method, particularly if one doesn't have a huge number of non-Microsoft processes being started on system startup. In any case, this sort of useless error message [for which I'd fire someone were I to learn it "left the house" such that there is *no* useful identifying information as to the source] it always comes down to some sort of process of elimination.

. . . the presumption of innocence, while essential in the legal realm, does not mean the elimination of common sense outside it. The willing suspension of disbelief has its limits, or should.
