How to run a command on command prompt startup in Windows

Question

If you want a defined set of commands to run every time you start a command prompt, the best way to achieve that would be to specify an init script in the AutoRun registry value. Create it like this (an expandable string value allows you to use environment variables like %USERPROFILE%):

reg add "HKCU\Software\Microsoft\Command Processor" /v AutoRun ^
  /t REG_EXPAND_SZ /d "%"USERPROFILE"%\init.cmd" /f

Then create a file init.cmd in your profile folder:

@echo off

command_A
command_B
...
cls

To remove these changes, delete the registry key:

reg delete "HKCU\Software\Microsoft\Command Processor" /v AutoRun

1. Make a shortcut
2. Go to the properties
3. The bit where it says: C:\Users\<Your username>\Desktop\cmd.exe, you put: -cmd /K <your command here>

e.g. C:\Users\Lewis\Desktop\cmd.exe -cmd /K color 1f

This is the way to launch 1 command without having to mess about with the registry.

Run multiple commands

You can also use & (and) operator to execute multiple commands.

Eg.

C:\Users\Lewis\Desktop\cmd.exe -cmd /K color 1f & H: & <your command>

I found my answer: I should use the /K switch, using which I can enter a new command on the opened command prompt.

E.g. cmd /K cls will open a command prompt for me and clear it. (Answer for question 1)

and

cmd /K MyBatchFile.bat will start a command prompt, execute the batch file and stay on the command prompt and will not exit. (Answer for question 2).

First, you need to press Windows Key + R. In the box that appears, type "regedit" (without the quotes). The Windows Registry Editor should open. Now, locate to HKEY_CURRENT_USER/Software/Microsoft/Command Processor. Once you have clicked on Command Processor on the left side, click Edit on the top bar. Then go to New > String Value in the Edit menu. Rename the String Value that appears to Autorun. Right click on Autorun and select Modify. Under the "Value Data" area, type in the commands you want to run. You can run multiple by typing && between them.

Expanding a bit, here is an alternative for Windows 10 where multiple aliases can be defined and applied to the Command Prompt upon execution.

1. Create a file called init.cmd containing aliases on your %USERPROFILE% folder:

init.cmd

@echo off
doskey c=cls
doskey d=cd %USERPROFILE%\Desktop
doskey e=explorer $*
doskey g=git status
doskey l=dir /a $*

2. Register it to be applied whenever the Command Prompt is executed:

In the Command Prompt, run:

reg add "HKCU\Software\Microsoft\Command Processor" /v AutoRun /t REG_EXPAND_SZ /d "%"USERPROFILE"%\init.cmd" /f

Done

Now the contents of init.cmd will run for executions of cmd.exe namely from:

• Taskbar shortcut
• WIN+R cmd
• By typing cmd in the File Explorer address bar
• By running cmd.exe directly from C:\Windows\System32

After registering these settings just remember to close/open:

• The Command Prompt so the settings are applied
• The File Explorer, if you use to launch the cmd via File Explorer address bar

To unregister it, run:

reg delete "HKCU\Software\Microsoft\Command Processor" /v AutoRun
