Upgrading a HP computer from Windows 7 to Windows 10

Prerequisites

Find the serial number of your computer, it may be useful later

A computer that has a Windows 10 license but was bought with Windows 7 pro installed (the Windows 7 downgrade option was selected when ordering the computer)

If you are not sure if you have this option, you can call the HP Professional hotline and ask: +33.1.70.48.53.19

You can also check the warranty status on the Product Warranty Check page

A USB stick with 16+ Gb for downloading the installation files
