Today Microsoft decide to release the new version Window 10 to the public in there live keynotes conference early today, The biggest announcement of all Window 10 will be free for one year. Who is eligible to receive free window 10 upgrade? So far I only heard window 7 users and Window 8.1 users? After one year we do not know how much you have to pay to retain your license of Window 10 in 2016? Would you stay Window platform or switch to Apple or Google OS. I am probably thinking about switching to apple computer my next purchase because Window are moving on subscription business model. It's the biggest mistake of all time why you need to keep bother your users. It's time to renew subscription or else. You are going to lose all your data for good?
