The wmic.exe file imports console functions like SetConsoleMode() and 
SetConsoleScreenBufferSize() from kernel32.dll. I presume that wmic 
performs some direct console I/O which conflicts with Cygwin's tty. This 
can be prevented by redirecting the standard input. But then wmic 
creates an empty file 'TempWmicBatchFile.bat' in current directory ...

There is no difference in this case. Wmic hangs in Windows console, 
mintty, rxvt and xterm if run without redirection from a Cygwin shell.
