## What it is
pyenv-win is a Windows port of pyenv, a simple Python version management tool that lets you install and switch between multiple Python versions. It follows the single-purpose UNIX tool tradition and is installed via PowerShell or pip.

## Use cases
- manage multiple python versions on windows
- switch python version per project
- install a specific python version
- set a global default python version
- replace pyenv on windows since pyenv doesn't support it
- pin python version for a repo

## When to choose
- you develop Python on Windows and need multiple versions side by side
- you want pyenv-like workflow (global/local/shell versions) on Windows
- you need to pin a Python version per project via .python-version files

## When to avoid
- you are on Linux or macOS, where the original pyenv works natively
- you want full virtual environment management - pair it with venv or virtualenv
- you need a cross-platform version manager like asdf or mise
