 Direct OEMs are officially held liable for things such as installation/recovery media, and as such were commonly provided until the late-2000s.These were then phased out in favor of recovery partitions located on the primary storage drive of the PC (and available for order from the manufacturer upon request) for the user to repair or restore their systems to the factory state.This not only cut down on costs, but was also a consequence of the gradual obsolescence and phasing out of optical media from 2010 onward.
