This is what I was trying to explain in my previous post. The larger companies, specialy the financial ones, have very good reasons for NOT wanting to upgrade to 10. My company is relativelly small company with only a couple of thusands of users and Win 7 licenses, but all out laptops have custom build images, with special applications installed by default, etc. Because of Life Cycle Management and specially budget, upgrading to Win 10 is not only unpractical for now, but also funancially not feasible. For the user's purpose, Win 7 is perfect, so why do you need to upgrade all company to a different OS of that is not required.
However we are buying NEW laptops almost monthly, and the old ones are replaced by HP based on a special contract our company have with them.
