Are you beginning to miss UAC yet To turn it back on, follow the same procedure as above (except you select the check box, of course). But note: This is one of those settings that a standard user can t make. You must log on as an administrator to restore UAC. Although the UAC prompts are sometimes intrusive, that s the point. First, they provide a not-so-subtle reminder that what you re about to do has systemwide effect. But most important, it prevents a malicious application from silently installing without your knowledge. Most spyware, viruses, and other malware get installed as a direct, albeit unintended, result of a user action, such as clicking a link. When you click a link that you think is going to display some pretty pictures, wouldn t you be pleased to have UAC tell you that it s attempting to install a program One misperception about UAC is that it doesn t let you do certain things, or that it locks you out of your own computer. In fact, UAC doesn t prevent anything all it does is inform you when an application requires administrator access. Remember that, even though you re logged in with an administrator account, you ordinarily run as a standard user. Need to run something that requires full administrator privileges Simply respond to the prompt. (If you find that you can t access certain folders and files, it s likely that the restriction is imposed by NTFS permissions which are unrelated to UAC. For information about NTFS, see 29, Controlling Access to Files and Folders. )

Reading from and writing to the console are two of the most fundamental uses of I/O, especially for server-side applications. Despite improvements in logging and debugging tools, writing to the console is still a prevalent means of tracking activity and problems in code. During development we still find console output to be the quickest and simplest means of getting a handle on a tricky problem. Reading from the console is less common but is still an important tool. A good UI goes a long way, but sometimes there is no substitute for grabbing a keystroke straight from the user. In Java, the console is exposed to the programmer as a set of streams obtained through the java.lang.System class. The .NET Framework puts all of the console functions in the System.Console class. The Console class is a wrapper around three streams, which are accessible via read-only properties. These are shown alongside their Java equivalents in Table 10-1.
