Message Queuing (also known as MSMQ) is a messaging infrastructure and a development tool for creating distributed messaging applications for Microsoft® Windows® operating systems. Applications developed for Message Queuing send messages to queues, which are temporary storage locations, from which messages can proceed to their final destination as conditions permit. Such applications can communicate across heterogeneous networks and can send messages between computers that might be temporarily unable to connect to one another. Message Queuing provides the following benefits:
| • | Guaranteed message delivery |
| • | Efficient routing |
| • | Improved security |
| • | Support for sending messages within transactions |
| • | Priority-based messaging |
Software products with these features are often referred to in the industry as:
| • | Message-queuing software |
| • | Store-and-forward software |
| • | Message-oriented middleware |
With Message Queuing, end users can communicate across networks and computers that might be offline, regardless of the current state of the network and computers. System administrators can use Message Queuing to efficiently manage large, complex networks of computers and message queues.
Message Queuing is not installed by default. You can install it from Programs in Control Panel. After it is installed, you can manage Message Queuing by using the Computer Management Microsoft Management Console (MMC) snap-in. To open Computer Management, click Start, right-click Computer, and then click Manage.

Utilities and SDK for Subsystem for UNIX-based applications is an add-on component for Subsystem for UNIX-based Applications (SUA). SUA is a source-compatibility subsystem for compiling and running custom UNIX-based applications on a computer running any of the following Windows operating systems:
| • | Windows Server 2003 R2 |
| • | Windows Vista Enterprise Edition |
| • | Windows Vista Ultimate Edition |
Because SUA provides an operating system for POSIX (Portable Operating System Interface for UNIX) processes, administrators can compile and run their applications in SUA with little or no change to their original source code.
SUA also supports case-sensitive file names, job control, compilation tools, and the use of over 300 UNIX commands, utilities, and shell scripts. The Web download contains many SVR-5 utilities and a software download kit (SDK) for creating or porting applications to run on SUA. Administrators can also port or download many UNIX/Linux utilities to run on SUA. This allows UNIX administrators to re-use existing skills and even scripts to manage applications, security permissions, and user passwords.
