Maximum PC: Microsoft has been granted a patent for "Windows 365" by the United States Patent and Trademark Office (USPTO), and of course the immediate reaction is that Windows is headed towards a subscription model similar to Office 365. Indeed that may be the case, though from everything that we know, it probably won't apply to Windows 10, which will remain a free upgrade for Windows 7 and Windows 8.1 users for the first year. Some people took the free upgrade announcement to mean that after the first year, a subscription fee would kick in. That's not my understanding of things, though the Windows 365 trademark is certainly an interesting development. Here are three possible scenarios I see playing out.
