This one comes across as a real boon to system administrators everywhere. The days of manually noting the updates rolled out to computers in an office are long gone: the Office Update Inventory Tool enables administrators to check several computers for the status of Microsoft Office 2000, XP, 2003 and 2007 updates.
From a central location, administrators can run this add-on on client computers to find which Office updates have already been installed, which haven’t, and which updates require administrator privileges. Of course, the add-on needs to be installed on every computer before the sys-admin gets to use his new-found powers.
