Windows can install upgrades before establishing a web connection because manufacturers often include updated versions of the operating system in the factory image. This allows the OS to be current upon unboxing without requiring immediate internet access. These updates can include security patches and other improvements, which may be installed automatically in the background during the initial setup or subsequent restarts. The factory image approach enables widespread distribution of Windows, making it standard for new computers to come with a preinstalled OS. While some vendors offer computers with Linux pre-installed, they may charge more due to the lack of additional software revenue from bundled applications. Comparisons between Linux and Windows systems show that Linux options can sometimes offer better specifications for the same price, such as increased storage.
