The windows system is an operating system that controls a computer. It runs programs that control hardware such as printers and scanners, and it stores data such as photos, documents and music.
It also manages memory, and it allows users to connect a variety of devices. It was first developed in November 1985 and has been updated several times since then, as memory sizes have increased and processing chips have evolved.
History
Microsoft first introduced Windows in 1985, and it’s been updated regularly ever since to keep pace with increasing processing power and changing computer technology. It has a number of versions in the family, including Windows 1 to 10 for desktop computers, and Windows for Workgroups for professional use.
The first version was a graphical shell that could be installed on top of MS-DOS and included programs such as Windows Paint, a graphics painting program; Windows Write, a simple word processor; and Calendar, an appointment scheduler. In 1987, IBM and Microsoft began developing OS/2, which took full advantage of protected mode and memory-management features on the Intel 80286 processor and offered standardized hardware interfaces for program user interfaces. However, tensions arose in the partnership as both companies worked to develop their own GUI systems for PCs.
Basic functions
Facilitates Hardware and Software Compatibility: Windows allows multiple programs and applications to run simultaneously on the same computer and supports plug-and-play devices like printers and scanners. It also facilitates file sharing between computers and mobile devices in a network.
Manages Memory: OS assigns and deals with memory in volatile main memory and non-volatile secondary storage to keep programs running efficiently. It also ensures that data is accessed properly, through techniques such as paging and segmentation.
Understand Desktop and Start Menu: Familiarity with the desktop environment and system tray gives you a centralized location to access applications, files, and settings. The operating system also features a variety of icons that represent applications and functions, including the recycle bin, which opens deleted files for review or restoration.
Advanced functions
Aside from its basic functions, Windows has many advanced features that allow users to tailor it to their specific needs. For example, the ability to pass parameters to a function allows users to customize its behavior.
Moreover, Windows is compatible with applications from third-party developers, which offers more choices and versatility for users. It also has an array of hardware support, including USB and HDMI ports, which provide more options for connectivity.
Additionally, Microsoft provides a number of utilities for its Windows operating system, such as Disk Management, DISKPART, Hosts File, Task Scheduler, Services Menu, Event Viewer, Windows Memory Diagnostic, Resource Monitor, and Reliability Monitor. These tools help in troubleshooting issues and resolving them quickly. Moreover, they are easy to use and offer flexibility for different scenarios.
Installation
Windows is a program that lets all the different components of your computer talk to each other. This makes it easy to use, even for beginners. It also has a number of other features, including multitasking and plug-and-play support for peripheral devices.
To install Windows, you need a compatible computer with an empty disk or partition. Make sure that the hardware drivers you need are available and have been saved to a DVD or flash drive, so you can reinstall them after installing the operating system.
To create Windows installation media, connect your device to the Internet and run the Microsoft Windows Media Creation Tool. Select the language, edition, and architecture (64-bit or 32-bit) that matches your device. Click Next. You may be asked to enter a 25-character product key, but this isn’t required for digital licenses.
Maintenance
Keeping your Windows operating system up-to-date is one of the most important maintenance tasks. This keeps your computer secure, and it also allows you to get the best performance out of your computer.
It checks for updates and installs them automatically, without you having to do anything. It also runs security scans to look for viruses and malware.
The Troubleshooter will also fix any hard disk volume errors that are causing free space issues, like lost clusters, cross-linked files, and directory errors. It will also remove broken desktop icons and shortcuts, and it will delete error reports and logs that are more than a month old.
It will perform automated system optimization on a daily basis, but it will postpone the scheduled tasks if your computer isn’t powered on or you are actively using it. The maintenance schedule is based on an analysis of the impact to user experience, hardware performance, and energy efficiency.
