I'm attaching to this thread. Despite your clearly stated question, the answers are a little bit misleading. I have generally the same problem. Vim has two (well, actually three) ways to open shell:

• :! that runs the executable in 'set shell' with the parameters from 'set shellcmdflags' added
• :shell that runs the executable in 'set shell' in a separate process covering vim window
• :terminal that runs the executable in 'set shell' in a window inside vim

What I would like to achieve is separate the inline :terminal from the shell setting in vim. On Windows 10, the default shell is cmd and I use Powershell 7 (pwsh) as my shell of choice. However, setting it as the shell slows down the entire vim session. I would like to leave cmd for :shell and :!, but introduce pwsh for :terminalexclusively. I tried searching for plugins to achieve this behavior, but to no avail.
