ADB and Fastboot are arguably two of the most indispensable tools used when working with Android devices. If you really want to modify, debug, and tweak along with their countless uses in rooting, and other procedures ADB and Fastboot are a must for any Android device owner. Typically if you want to install ADB and Fastboot you have to download and setup the Android SDK (If you really want to learn about Android Development I highly recommend downloading and installing the full Android SDK from here), but this can be unnecessary for people who just want to install ADB and Fastboot. To simply the process I created a windows installer that will install the latest version of ADB and Fastboot for you quickly and easily. The total installation of Minimal ADB and Fastboot is around 2 MB in size (Compared to the 90+ MB size of the Android SDK Tools, and 425+ MB size of the complete Android SDK) making it very lightweight.
