HP290 G2 MT Core i5 full b1 s1 v1

HP290 G2 MT
Microsoft Windows 10 (64-bit)

Est-il possible de "downgrade" WIN10 64bit à WIN7 64bit?

J'ai une ancienne application qui doit être tournée sur un système d'exploitation ne dépassant pas Windows 7 64 bits. Mon grand problème réside sur le contrôleur hôte Intel(R) USB 3.1 eXtensible 1.10. Le windows7 installation n'arrive pas à trouver les clavier et souris (tous USB). J'ai déjà utilisé USB Bootable confectionné par Rufus-3.8, Gigabyte tools, Installer_creator et DISM GUI 4.0 mais le problème reste entier.

Les "desktop" sont tous livrés avec Windows10 64 bit.

 

Je serais très reconnaissant si quelqu'un arrivait à m'aider.

I must use my old software with Windows7 system 64bit.

Intel USB 3.1 eXtensible 1.10 controller don't reconized  my USB keyboard and mouse during the windows7 installation. There's no ps/2 port for that.

I tryed use USB Bootable built by Rufus-3.8, Gigabyte tools, Installer_creator and DISM GUI 4.0, It doesn't work.

 

The desktop are with Windows10 64 bit, and I must install windows7 64bit.

 

Does anyone can help ?
