Varpanel is a simple but powerful tool that allows to change the value of any user or system variable. The Windows default environment variable editor provides a terrible experience: Varpanel is a better way to edit environment variables.
Features:
- Varpanel is resizable
- Multi-line editing for multi-valued environment variables
- File/directory browser for editing PATHs
- Elevates only if you need to edit system environment variables (Admin mode)
- Broadcasts WM_SETTINGCHANGE so that running processes may update their environment
