echo [ What? ]
echo.
echo # Named after chmod, chmac is a command-line-interface ^(CLI^) tool for
echo Windows that changes or randomizes MAC addresses of specified network
echo adapters, e.g. for a client device to reuse public Wi-Fi hotspot that
echo has past usage limit for the day.
echo.
echo An easy-to-use interactive console is available, alongside command-line
echo parameters, e.g. for scheduling jobs with Task Scheduler. ChMac also has
echo support for recurrence built-in.
echo.
echo [ Features ]
echo.
echo # Change MAC addresses on Windows automatically or manually
echo.
echo Automatically change MAC addresses on set intervals. This is useful to
echo reconnect to some free public Wi-Fi hotspots that impose a time limit by
echo recogniziung MAC addresses to prevent the same device from reconnecting
echo.
echo # Randomize MAC addresses for better security using public Wi-Fi
echo.
echo Generate new MAC addresses randomly based on a customizable list of
echo organizationally unique identifiers ^(OUI^)
echo.
echo # Optionally leverages DevCon.exe to simply the process by automatically
echo disabling and re-enabling network interface card ^(NIC^)
echo.
echo ChMac also works without DevCon by showing the Network Connections
echo folder when finished, so that users can manually disable and re-enable
echo NIC for new settings to take effect
echo.
echo On first launch, users are guided to download DevCon with convenient
echo automatic and manual options
echo.
echo # Restore original MAC address
echo.
echo # Error checking + rich return codes for scripting or other possibilities
echo.
echo # While portable by default, it can be installed ^(using setup.exe^) to
echo enable the 'ChMac' command anywhere for ease of use, by adding to Run
echo prompt and PATH environmental variable ^(feature available since v2.0^)
echo.
echo # Free and open-source software written in Windows Batch language
echo.
echo # Supports Windows 2000/XP/Vista/7/8/8.1/10 and Server 2000-2019
echo.
echo # Easy-to-use interactive console + command-line mode accepting parameters
echo.
echo Just follow instructions on screen for the interactive console.
