After I uninstalled vs-code the popup message appeared:
Your extensions and settings will not be removed.
Now I want to remove all of the vs-code settings and install it as a new user. How can I do this?
If you want to completely delete settings, go to %AppData%\Code and delete the whole folder. Then uninstall and install it again.
If you want to delete all extensions too, delete the extensions folder on %UserProfile%\.vscode.
