The DLL doesn't belong to Windows, but to some other software that also uses
OpenSSL and put the DLL there.

Unfortunately the system32 directory has priority and is processed before PATH
is searched (see also [1]).  AFAIK the only way is to (re)move the DLL from
system32 or to put the OSGeo4W version into each osgeo4w directory where
executables that load it are.
