Windows only: WinUpdatesList, a free utility for Windows, lets you see what updates your system has grabbed during its existence, and provides quick links to Microsoft Knowledge Base articles related to each one. Why would you use this instead of heading to the Windows Update server, you ask? If you’re without internet and want to see which update borked your system, perhaps, or if you want to pre-download and slipstream updates into a custom-made Windows install CD. Since it’s a self-contained app, no real installation is required, so use and discard at your discretion. WinUpdatesList is a free download for Windows systems (except Vista).
