Windows 10 is a series of personal computer operating systems produced by Microsoft as part of its Windows NT family of operating systems. Devices in enterprise environments can receive these updates at a slower pace, or use long-term support milestones that only receive critical updates, such as security patches, over their ten-year lifespan of extended support. This release contains two ISO images and 74 executable svf files. All exe files are created from original ISOs for each language. This is done with SmartVersion, a program that calculates the difference between two files (one of which is used as the source) and then creates an svf file based on that difference.
