Product key is stored in BIOS, so there is no need to use any app to read it.

Download a tool to create bootable media from Microsoft website and install Windows 8.1 using it:


Moreover at first, you may try to restore your Windows 10 to factory state (do a backup of all important data first). Go to Settings -> Recovery -> Reset this PC and select Remove everything.
