Windows is an operating system that acts as a bridge between the user, software, and hardware. It ensures that programs run smoothly, files are saved properly, and external devices like printers or mice work seamlessly with your computer. Below is an overview of how Windows functions on a technical and practical level.
The kernel is the core of Windows. It manages communication between software and hardware, handling tasks such as memory management, resource allocation, and multitasking.
On top of that sits the graphical user interface (GUI), which allows users to interact with the system visually, through windows, menus, and icons, without needing to understand the underlying code.
Windows uses the NTFS file system to store and organize data. NTFS supports:
File permissions and access control
Compression
With File Explorer, users can easily browse and manage folders and files.
Each user account has its own set of permissions to prevent unauthorized access or accidental system changes.
The Windows Registry is a central database that stores configuration settings for the system, applications, and users.
Changes made to hardware, installed programs, or system preferences are recorded here.
While powerful, the registry is sensitive, errors can cause system instability if not handled correctly.
Windows Update automatically delivers:
Security patches
Quality improvements
New features
These updates typically run in the background but can also be manually managed through the system settings.
Windows uses drivers to communicate with hardware components.
Drivers allow devices like printers, keyboards, or graphics cards to work properly with the operating system.
Through Device Manager, users can view, update, disable, or uninstall these drivers when needed.
Over the years, Microsoft has significantly strengthened Windows security, for both home users and businesses. The operating system includes multiple layers of protection to defend against viruses, malware, and unauthorized access.
Every Windows system allows users to have separate accounts with defined access levels.
Standard users can’t modify critical system settings, while administrators have full control. This helps prevent malicious software from making harmful changes without permission.
Windows also features User Account Control (UAC), which prompts users to confirm major changes. This adds an extra layer of protection by ensuring that only approved actions are carried out.
Windows Security is the built-in suite that includes Windows Defender Antivirus.
It protects your system from:
viruses
spyware
other malware threats
In addition, it offers:
Firewall & network protection
App & browser control (to block unsafe downloads and websites)
Security updates via Windows Update
These tools are enabled by default, providing solid protection without needing third-party antivirus software.
For enterprise use, Windows offers advanced security features such as:
BitLocker for full disk encryption
Windows Hello for biometric sign-in
Secured-core PCs for firmware-level protection
Microsoft Defender for Endpoint for advanced threat detection and response
Businesses can manage these features centrally through Microsoft Intune, Group Policy, or other endpoint management tools.
Windows is designed to run on a wide range of devices, from desktops and laptops to tablets, servers, and embedded systems. This broad compatibility makes it one of the most versatile operating systems in the world.
Windows supports dozens of languages through the Multilingual User Interface (MUI) system.
Users can easily change the display language without having to reinstall the entire system.
This is especially useful in international environments or when multiple users share the same computer.
Keyboard layouts, date formats, and other regional settings are also automatically adjusted based on the selected language.
Windows runs on multiple architectures:
x86 (32-bit) – becoming less common
x64 (64-bit) – the standard for most modern computers
ARM – mainly used in energy-efficient tablets and lightweight laptops
The ARM version of Windows (e.g., on the Surface Pro X) offers excellent battery life but has some limitations in terms of compatibility with older software.
Windows is known for its strong support for:
printers
mice and keyboards
external hard drives
monitors
audio and video cards
Most devices are automatically recognized and installed via plug-and-play.
In many cases, Windows Update takes care of downloading and installing the correct drivers.
