er name completion and Ctrl-F gives F ile and folder name completion. These key-strokes will display the first matching path. Thereafter, repeated pressing of the same control key will cycle through the list of matching paths.

Environment expansion preference can be set permanently in the registry HKLM | HKCU \Software\Microsoft\Command Processor\DelayedExpansion Set to either 0x1 or 0x0 /knetdiag /debug /knetdiag /fix The knetdiag switches are undocumented and work in XP only they list and (may) fix these networking issues. If /C or /K is specified, then the remainder of the command line is processed as an immediate command in the new shell. Multiple commands separated by the command separator '&' or ' && ' are accepted if surrounded by quotes. The following logic is used to process quote (") characters: 1. If all of the following conditions are met, then quote characters on the command line are preserved: - No /S switch (Strip quotes) - Exactly two quote characters - No special characters between the two quote characters, where special is one of: & < >( ) @ ^ | - There are one or more whitespace characters between the the two quote characters - The string between the two quote characters is the name of an executable file. 2. Otherwise, old behavior is to see if the first character is a quote character and if so, strip the leading character and remove the last quote character on the command line, preserving any text after the last quote character. To negate this behaviour use a double set of quotes "" at the start and end of the command line.
