HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun If /D was NOT specified on the command line, then when CMD.EXE starts, it looks for the following REG_SZ/REG_EXPAND_SZ registry variables, and if either or both are present, they are executed first. If so, strip the leading character and remove the last quote character on the command line, preserving any text after the last quote character. Otherwise, old behavior is to see if the first character is a quote character.
If /C or /K is specified, the remainder of the command line after the switch is processed as a command line, where the following logic is used to process quote (") characters:ġ. Also, for compatibility reasons, /X is the same as /E:ON, /Y is the same as /E:OFF and /R is the same as /C. Note that multiple commands separated by the command separator '&' are accepted for the string if it's surrounded by quotes.
