Instructions to install ADB drivers?

Hello, I bought my shield a while back, rooted in KitKat just to get my backup data from apps from my previous device transferred and then happily ungraded to Lollipop with the intention to stay unrooted since it means unlocking the bootloader which may void my warranty. Recently I came upon an app named Helium which I knew nothing about and which seems to be able to backup app data even without root, but to use the no-root version you need to have ADB drivers installed. I found a bunch of sets of ADB drivers, like for example this http://developer.download.nvidia.com...USB_driver.zip but nowhere real instructions explaining how to install them in a Windows 7 PC. I've searched all over the place with no luck so help would be greatly appreciated. I installed drivers for my older device about 3 years ago so I've done it before but I can't remember a thing about it, even if it was a similar method that I had followed.



Thanks in advance, hope someone replies. Help a fellow keep his data backed up please! :D
