Uninstalling Terminal modification

[ReaderGuy42]

          1: Open your file manager and enable hidden files (Can usually reveal hidden files with `Ctrl-h`.)

2: Locate .bashrc in your home directory (/home/$USER/.bashrc) and open it with a text editor.
3: Scroll to the bottom of the file and delete only the following:

# Add to you ~/.bashrc file with: 'source ~/.themes/95/bashrc'

function msdos_pwd
{
    local dir="`pwd`"

    echo $dir | tr '/' '\\'
}

export PS1='C:`msdos_pwd`> '

echo 
echo
echo "Microsoft(R) Windows 95"
echo "   (C)Copyright Microsoft Corp 1981-1996."

I'm on Mint 21.2 and /.bashrc doesn't exist. I can find it in /etc but there it doesn't include the "Microsoft Windows" thing.

Could you please help me uninstall the terminal modification? I've figured out how to remove all the other themed things. Thanks!

/etc contains the original files, never modify those.

Try looking for the string everywhere:
grep / -rnwe 'Copyright Microsoft Corp'
