+wimlib can create XPRESS or LZX compressed WIM archives.  As of wimlib v1.0.3,
+the XPRESS compression ratio is slightly better than that provided by
+Microsoft's software, while the LZX compression ratio is approaching that of
+Microsoft's software but is not quite there yet.  Running time is as good as or
+better than Microsoft's software.
