When Microsoft launched its Windows 10 operating system, it knew that it had to convince customers to give it a try. The bad adoption of Windows 8 still haunted the company and it had to ensure that Windows 10 would not be a disappointment in regards to the adoption rate as well.
One of Microsoft's strategies to get customers to upgrade systems to Windows 10 was to offer it for free. Limited to the first year of release, Microsoft said, customers could upgrade systems running genuine versions of Windows 7 or Windows 8.1 to Windows 10 for free. The original license was upgraded to a digital license in the process.
