It can look like this:

tvnserver.exe -stop
reg add "HKLM\SOFTWARE\TightVNC\Server" /v Password /t REG_BINARY /d F0E43164F6C2E373 /f
reg add "HKLM\SOFTWARE\TightVNC\Server" /v UseVncAuthentication /t REG_DWORD /d 0x1 /f
tvnserver.exe -start

    what is F0E43164F6C2E373 representing here? – Firesh Jun 14 '21 at 07:56
  • @Firesh that's the password `12345678` encrypted using a hardcoded DES key (which is hardcoded in the TightVNC source code). Easiest approach may be to use TightVNC config tool to set the password to what you want, then copy the encrypted value from the registry, then you can set it using the command line on another machine. – Simon Kissane Dec 03 '22 at 02:21
