Disable Automatic Updates

WAU Manager
WAU Manager was built to fully replace the built in Windows Automatic Updating (WAU) system. However, unlike the latter, WAU Manger puts you in control of everything. With WAU Manager you can:
Update manually when desired with just a double-click on a dedicated desktop shortcut
Update automatically with the desired frequency. Once a day, once a month or once a year, or whatever you decide.
You get to choose whether the available updates are automatically downloaded and installed or not.
Easily uninstall several updates at once.
