How do you swap the primary mouse button via commandline in Windows 8 without a reboot?

Question

I've tried

RUNDLL32.EXE USER32.DLL,SwapMouseButton

But it doesn't work, even when run as administrator.

My goal is to make a .bat file that I can call via my fancy shmancy new mouse I bought that allows me to call any arbitrary command from a mouse click.

Answer 1

Swap mouse buttons from command line

We can swap mouse buttons by editing the registry value SwapMouseButtons under the registry key HKEY_CURRENT_USER\Control Panel\Mouse. To swap mouse buttons we need to set its value to 1.

Same thing can be done from command line using the below command.

reg add "HKEY_CURRENT_USER\Control Panel\Mouse" /v SwapMouseButtons /t REG_SZ /d 1

It requires a logoff or reboot to make the changes effective.

Answer 2

I used the text below on windows 10 and saved it as sandbox_mouse_button_swap.wsb

Double-clicking that file opens up the sandbox with the mouse buttons swapped, no reboot required.

<Configuration>
  <LogonCommand>
    <Command>rundll32.exe user32.dll,SwapMouseButton</Command>
  </LogonCommand>
</Configuration>

Answer 3

I am no expert at this - I tried both the above solutions but it did not work and so I simply created a .bat file with the following command script, saved it to my Desktop and whenever I want to swap, I double-click the script to make it run and it does the job for me.

rundll32.exe user32.dll,SwapMouseButton
