Module windows_subprocess_reg_exe

source code

Reads the MS-Windows registry by calling a subprocess for reg.exe.

This is a fallback solution when neither winreg / _winreg, nor in case of Jython the Java APIs such as WindowsPref, JNA, or JNI are not available. This works also on Cygwin, when e.g. the path for kernel32.dll does not match for the ctypes.

Avoid using it due to serious performance impact compared to the others - but do when nothing else helps and the version information matters.
