Microsoft will issue seven security updates next Tuesday, including critical sets of patches for Windows and Internet Explorer.
The other four updates set for Tuesday are all rated "important" by Microsoft, meaning that they require some level of user interaction in order to be exploited. These four updates are all Windows-related. Two of them are for Vista and two of them are for Microsoft's other operating systems.
December will be a much busier month for system administrators than November was. Last month, Microsoft released just two updates.
