Windows-Update-Checker (KUC - Komm's Update Checker) is a small utility that will check what updates are installed, missing, or removable on your Windows 7, 2008, 8, and 8.1 systems.
A wealth of information can be had, including:
[KB#] The knowledge base (KB) number of the update [Version] The version number of the update [State] The installation state of the update: installed, install pending, staged, superseded. [Release Type] Update, Security Update, Hotfix, Language Pack, etc. [Install Time] The date and time the package was installed. [Package Identity] The (short) name of the package. [Language] If the package is language-dependent, you find the installation language here.
You can allow KUC to generate a packages.txt of your online system or create your own. An excellent utility that provides a great deal of information on Windows updates while remaining comfortable enough to use for even novice users.
