Some vertical markets use a lot of software that integrates with Microsoft Office applications. The result is that there is a much higher change of a Microsoft update breaking a critical application. [0] is a recent (September 2015) example of two Microsoft patches that were widely blocked in the legal industry until Microsoft released a follow up patch. iManage and Workshare, the products mentioned in the blog entry, are considered critical applications in any law firm that uses them. iManage is a widely used document management system (think primitive VCS with Office add-ins). All documents are stored in the DMS so access to it is critical to the business. Workshare is used for document comparison and metadata scrubbing. Metadata scrubbing is used on all outgoing emails.

Translation: "My feelings make me feel that the statement isn't right. Instead of finding out, I'm just going to say that I wish someone would tell this commenter they're wrong."

Translation: "Microsoft has lied about the content of their updates before."
