Microsoft first released Windows in 1985, and it is now one of the most popular operating systems available in the market. Its graphical user interface (GUI) is made to make it simple for people to interact with their computers. Users can access multiple apps and functions using the GUI, which is made up of graphical components like windows, icons, and menus.
Windows has evolved and been released in a number of different versions over the years, including Windows 3.0, Windows 95, Windows 98, Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 10 and Windows 11. One of the most significant differences between Windows 10 and Windows 11 is that the latter now supports Android apps from the Amazon App Store.
Who Invented Windows ?
Windows was created by Bill Gates and Paul Allen's Microsoft Corporation, which they co-founded. In 1985, MS-DOS—the default operating system for the majority of personal computers at the time was replaced by Windows as a graphical operating system shell. Since then, Windows has seen a number of improvements and has grown in popularity worldwide.
How Windows Works ?
The Windows operating system is based on a microkernel design, which means that its kernel, or core, is in charge of managing the machine's fundamental resources, like memory and processing time. User mode and kernel mode are the two ways the kernel can run. In User mode, applications have limited access to system resources, whereas in Kernel mode, the operating system has complete access to all system resources.
Stage 1:
Switching on a Windows computer is the first step in the boot-up process. The BIOS (Basic Input/Output System) does a power-on self-test (POST) when the computer is turned on to make sure that the hardware is working properly.
Stage 2:
Once Windows has started, the BIOS examines the settings of the machine and finds the bootable device, which is often the hard drive. The boot loader programme located on the hard drive receives control from the BIOS at that point.
Stage 3:
The operating system is loaded into memory by the boot loader programme. The boot loader programme locates the operating system's kernel file by reading the boot configuration information from the boot configuration file.
Stage 4:
The kernel, which serves as the operating system's heart, is in charge of controlling the hardware's fundamental resources, including memory and CPU time. The operating system is initialised and made ready for usage by the kernel.
Stage 5:
The device drivers is loaded next. Device drivers are smaller programmes that give the operating system access to hardware components like disc drives, printers, and keyboards. The operating system loads the required hardware drivers to handle the connected hardware devices.
Stage 6:
The logon screen appears once the operating system has started loading and the required device drivers have been set up. The user can access the operating system by entering their username and password on the login screen.
Stage 7:
The operating system establishes a user session for the user when they have provided their username and password. The task of managing the user's environment, which includes the desktop, programmes, and files, falls to the user session.
Stage 8:
The loading of the software completes the booting process for a Windows computer. Applications defined in the registry or the user's starting folder are both launched by the operating system. The user can then utilise the computer and interact with the programmes.

What are the DisAdvantages of Windows OS ?
The Windows operating system has a number of disadvantages:
Vulnerability to Viruses and Malware: Windows is susceptible to viruses and malware because of its widespread usage, which makes it a desirable target for online criminals. The operating system has a lengthy history of security flaws that can be used by spyware, viruses, worms, and other harmful programmes. Although Windows has several built-in security mechanisms, like Windows Defender and Firewall, they are not impenetrable and can be disregarded by malicious users. Furthermore, many users may be running outdated, susceptible versions of Windows because they are not careful about updating their software.
High Cost: Windows isn't free and can be expensive, especially for customers at the enterprise level who need numerous licences. To defend against potential threats, businesses may also need to make significant hardware and software security investments.
Compatibility Issues: Although Windows is commonly used, running older applications or hardware can cause compatibility problems. For instance, certain older programmes might not operate properly on more recent versions of Windows, and users might have to run them in compatibility mode or using virtualization software. Compatibility problems may also arise from some hardware component's outdated drivers not being compatible with more recent Windows versions.
Resource-Hungry: Particularly on older systems, Windows has a reputation for being resource-hungry. On laptops and other mobile devices, this may result in sluggish performance and shorter battery life. The indexing service and system restore are only two examples of the built-in capabilities in Windows that can use up a lot of system resources. To increase performance, users might need to modify these settings or upgrade their gear.
Complexity: Windows can be challenging, particularly for novice users. It may be challenging to use, navigate, and comprehend due to this intricacy. To fully utilise the operating system, users may need to consult online resources or enlist the assistance of professionals because it contains a lot of built-in functions and settings that can be confusing to understand.
Forced Updates: Users frequently have to restart their computers at inconvenient times and are obliged to install Windows updates. Workplace disruption and issues may result if the upgrade has compatibility problems with other software or hardware. Users may also not want to install some updates, but they must do so in order to get security patches and other crucial changes.
Fragmentation: Fragmentation of the Windows registry over time might result in decreased performance and stability problems. Software installation and removal, adjusting system settings, and other typical operating system usage can all contribute to this. To fix these problems, users might need to run a registry cleanup or defragmenter.
Inefficient File Management: It might be challenging to manage and find files due to the ineffectiveness and disorganisation of the Windows file system. For instance, it may be challenging to identify and arrange files and folders if they are dispersed across several hard drives. Additionally, temporary files and other unnecessary data might clog the file system, aggravating the issue.
User Account Control Pop-ups: User Account Control (UAC), a feature of Windows, has the ability to produce a lot of pop-up windows, disrupting the user's productivity and possibly jeopardising security. The function can be inconvenient and disruptive, but it is intended to guard against malware and prevent unauthorised changes to the operating system. Users may occasionally need to change the UAC settings or disable it entirely to enhance their experience.
