Windows OS installation on a laptop or desktop involves setting up the operating system (OS) from scratch or re-installing it to ensure the computer functions optimally. The process typically includes creating a bootable USB drive with the Windows installation files, configuring BIOS/UEFI settings, and following on-screen prompts to install the OS. This includes selecting language preferences, entering a product key (if necessary), and partitioning the hard drive. Once installed, users can customize settings, install drivers, and set up applications for everyday use. Proper installation ensures system stability, security, and performance.
