+## How do I disable the automatic search/usage of the `.venv` virtual environment?
+
+If you look at the [diagram of how the Launcher chooses what Python interpreter/environment to use](index.md#diagram-of-how-the-python-launcher-selects-a-python-interpreter), you will notice that the `.venv` virtual environment is only selected if you **don't** specify a verison restriction, e.g. `py -3` disables the search.
+
+The thinking behind this is that if you want a specific Python version then you aren't interested in a specific virtual environmen., Thus the search for `.venv` is skipped when **any** specific version is requested.
