Known Limitations

SetX writes variables to the master environment in the registry. Variables set with SetX are only available in future command windows, not in the current command window. This is a limitation of Windows 2000.
When accessing REG_MULTI_SZ values in the registry, only the first item is extracted and used.
Only the HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE hives are supported.
Values added to the User or Machine environments cannot be removed with SetX (as a corresponding one can be removed from the local environment by using SET with a variable name and no value.)
Registry values of type REG_DWORD are extracted and used in hexadecimal mode.
File Mode supports parsing of CR-LF text files only.
