Description:
Command extensions are used to change the behavior of various standard command processor functions such as CD, MD, DEL, PROMPT and SET. They are enabled by default. By using this tweak you can control whether command extensions are enabled or disabled.
The command extensions involve changes and/or additions to the following commands: DEL or ERASE, COLOR, CD or CHDIR, MD or MKDIR, PROMPT, PUSHD, POPD, SET, SETLOCAL, ENDLOCAL, IF, FOR, CALL, SHIFT, GOTO, START (also includes changes to external command invocation), ASSOC, FTYPE.
For this, go to Start > Run menu, enter “regedit” and navigate to the registry path listed below. Now, right-click and modify the DWORD value “EnableExtensions”, in the right panel, to disable command extensions. However, if you want to get back to the original state and enable command extensions, change the value to “1”.
The changes take effect after a restart or logoff.
NOTE:
To get specific details, type “commandname /?” to view the help. You may also disable extensions for a particular invocation by using the /E:OFF switch.
