ThinkVantage System Update 3.14 can automatically install and apply updates to software, drivers, firmware and BIOS all from one application. It can be configured to run fully automated where it downloads and installs updates on a scheduled basis or manual mode, where you control how and when it runs.
System Update installs under Windows 2000, XP and Vista and requires Microsoft .NET Framework version 2.0 or better to work correctly. The newest release of System Update, version 3.14, seems to be more stable and work much better. I had the previous release installed and frequently received an error message while gathering information and the application would stop. This new release has run flawlessly for the several times I have run it. I usually like to download and install updates myself and am cautious about applying updates to drivers from Windows Update, but so far this application has been pretty nice to use.
