When information and rumors about Windows 10 began to circulate last year the idea of a subscription-based operating system came up quite a few times. While Microsoft has since confirmed that individual users of Windows 7 and 8 will be able to upgrade to Windows 10 for free it has made it clear that enterprise users will not be granted that luxury. Pricing hasn’t been confirmed but the fact that Microsoft just trademarked “Windows 365,” it’s certainly possible that the company will charge a subscription fee.
