RunProcess does not run shell commands (things you might type into your terminal). It runs processes, as the name suggests.

If you want to run shell commands, then you have these options:

Run (it does not give you the output)

Import["!yourcommand", "String"] or similar (to get the output)

Run your shell with RunProcess/StartProcess and pass the commands to it on its standard input. StartProcess has an example like this.

For this specific task, run cmd.exe with the /c flag and tell it what to execute. RunProcess has an example like this.

Import["! tasklist | find /i "explorer.exe"", "String"] works! ;)
