Just trying to back up some files onto my old pc, an Emachines running win7. When connected to my win10 Lenovo laptop, everything works fine, both MPT and PTP show up and everything is recognized. But with my windows 7, only PTP allows the computer to see the phone? I've tried USB debugging, changing ports, uninstall/reinstalling drivers, and changing cables but nothing seems to work. The exact same cables I used on my laptop do not work on the windows 7? Other phones easily connect to my Windows 7. I don't wanna do anything crazy or root the phone, and if I have to I'll just use the laptop but what's the deal?
