Windows system is an operating system that runs on personal computers. Introduced by Microsoft in 1985, it included the first graphical user interface for IBM-compatible PCs and quickly dominated the PC market.
In 2015, Microsoft released Windows 10, which incorporated features such as Cortana, a digital assistant like Apple’s Siri, and a more traditional desktop layout. It also offers effective security features such as an antivirus and an antimalware program.
The GUI
A GUI is an operating system that enables users to navigate a computer through the use of windows, icons and menus, rather than by typing commands at a text prompt. The GUI was first introduced by the Xerox Palo Alto Research Center in the 1970s, and Apple engineers incorporated it into the Macintosh system software.
The graphical interface is now the standard for computers; it has become an inseparable part of our cultural environment. It has made computers easier to operate, and it is more fun than typing complex commands at a text prompt.
The Windows system uses several different windows for programs, video, documents and files. It also supports multitasking, which allows the user to watch a movie while writing a letter, or play Minesweeper while editing a file. A window contains a title, a scroll bar for vertical movement and horizontal navigation, and a tab for opening and closing the window. A toolbar includes buttons, widgets, search fields and other tools that control software functions in a row.
The Kernel
The Kernel is the core program that does all the talking between the hardware and software applications. It’s the first thing that loads into memory when you turn on a computer or mobile device and remains in memory until it’s shut down again.
It’s a bridge that efficiently manages interaction between application programs and the physical hardware components of a computer, such as memory, processor, and disk drives. It does this using system calls and inter-process communication. It’s loaded into privileged mode, so only it can interact with the hardware directly, unlike user processes which cannot do this.
The kernel can also schedule the execution of application programs and re-assign resources between them. It keeps track of the region of memory that belongs to each process and protects this area from unauthorized access by other (possibly malicious) processes. Security is a major feature of Windows, and the kernel plays an important role in this. It supports various measures, such as Secure Boot, Control Flow Guard, BitLocker disk encryption, and a firewall.
The Message Queue
A message queue uncouples the consumer and producer components of your application so that each processes new messages asynchronously without clogging up the other. As a result, your application runs more reliably and you get a much clearer picture of transactional activity.
The client runtime interacts with the Message Queue server to perform message production and delivery operations. It also uses the Message Queue administration tools to configure the connection and locate physical destinations, and manage administered objects.
The Message Queue administration tool is a set of command line utilities and a graphical user interface (GUI) called the Administration Console. The Administration Console is useful for managing the basic functions of a broker, but it does not support some more specialized administrative tasks.
The Services
The services are an important part of the windows system and are a valuable tool for software developers and system administrators. They allow for the automation of processes and background tasks that can operate without user interaction or presence, thereby increasing the security and reliability of the system.
They can run continuously or periodically and are managed by the Service Control Manager. They can also have elevated privileges and are optimized for efficient resource consumption, making them a powerful solution for background operations and automated backups.
Services can be started automatically at boot time or delayed by the SCM, allowing them to operate independently of user login and activity. They can also be paused, resumed or disabled. Right-clicking on a service offers the options to start, stop or pause the service and double-clicking reveals its properties, allowing you to change its startup type and other information. The pause option only pauses the service for accounts that do not have service privileges.
