Microsoft have announced that 'Original Equipment Manufacturers' will no longer be allowed to preinstall win 7 or win 8.1 on computers after October 31 2016. Win 7 is on over 50% of desktop computers and Microsoft clearly wants to change these to win 10 so that the Win 7 perpetual licence's are replaced with a service licence allowing a yearly service fee. This date may be the trigger for determining the definition of 'Life of the device' terminology that is used in the 'End user licence' agreement of Win 10. In short, when a fee is required to run the mandatory updates.
