You have to install the android sdk. In the downloads section of the guide you can get the first link (the zip file) or download it directly from Google:
Android SDK | Android Developers

If you download from google, unzip the directory "android-sdk-windows" to c:\ and rename it "sdk." Then run sdk-setup.exe

adb is in the sdk\tools directory.
