Ready-to-install Odoo packages can be found at https://download.odoo.com, available for any of the currently supported Odoo versions, as well as for the master branch (the latest development version). You can find the Windows (.exe) installers, alongside the Debian (.deb) and CentOS (.rpm) packages.
To install on Windows, find the latest .exe build in the nightly directory and install it. The all-in-one installation is straightforward, as it provides all that you will need to run Odoo; Python 3, a PostgreSQL database server, the Odoo server, and all Odoo additional dependencies. A Windows service is also created to automatically start the Odoo and PostgreSQL services when your machine starts.
