Microsoft Knowledge Base was (as of 2020, almost all articles now produce the message : Sorry, page not found) a repository of over 150,000 articles made available to the public by Microsoft Corporation. It contains information on many problems encountered by users of Microsoft products. Each article bears an ID number and articles are often referred to by their Knowledge Base (KB) ID. Microsoft Windows update names typically start with the letters "KB", this is in reference to the specific article on that issue. Previously, the "Q" letter was used.
