The way that Microsoft fixed it, however, is not so good. A lack of transparency is a particular bugbear of mine when it comes to anything security-related, and this vulnerability patch is no exception. The problem is that Microsoft created a new and empty folder with the security update, the appearance of which led to a totally understandable debate in tech forums and on Reddit as well as other social media platforms. What was this "inetpub" folder, how did it get there, is it dangerous, is Microsoft using it to collect data, and should I delete it?
