Bold move here by Microsoft but also not.. what they actually trying very hard to do, is force business/corporate, personal.. basically most of the user base on to Windows 10 by giving it away for a year. Why? Support costs saving and single base to work from and support for the future. I'm sure they ran the numbers and found that by doing this.. they will likely save longer term besides suddnely giving people access to their 'App Store' to push additional sales.. clever 
Clearly it's a very different strategy from those adopted by the older gen CEOs of Microsoft..
