Hello, I have about 50 HP and Dell laptops that I need to format and reload. Its a good mix of systems but the majorities of the systems are HP Compaq's 6910p and the remainder of them are Dell Latitude E6400 and Dell Latitude E6420. My question is I really don't want to have to reload one by one, unless I have too, any suggestions? I was thinking Acronis but not sure with my windows activations ..... I have a product key information sheet for most of the systems that contain COA information and the key. Also, it looks like windows 7 key and some of the system have been upgraded to windows 10
