No, I assume that a "texlua.exe" prepared by an attacker only needs
msvcrt.dll.  The latter provides everything needed in order to give
you more free disk space.

But I think this is not Context related.  It's a Windows problem which
cannot be solved.  If someone places a rogue texlua.exe in your
current working directory, you are lost.  ... Or at least your files.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
