A Pavilion of HP Desktops & All-In-Ones

Does anyone know if the desktops come with a recovery disk?

Very few computers come with recovery disks anymore. Some will have a recovery partition on the hard drive. The manufacturer’s site will usually have instructions on making your own recover set or information on ordering one.

Do these have win 8.1 pro?

The features and specs will state which version of Windows that unit comes with. It can vary from unit to unit.
