I bet they are going to also announce that they are dropping support for 7 and 8 only a couple of weeks after 10 is out. Just to get people to take the bait.
If I remember correctly it's completely free to upgrade to win 10 from 7 and 8, but the offer is only on the table for a year. After the first year, you will have to pay full price for the upgrade. I'll try to find the couple of articles where this is explained when I get a sec.
People calm down. Windows will remain being an operating system, and not an operating system that requires you to remain online to check your licence.
I work partially as microsoft partner so lets say some things right on:
Support
- Windows 7 end of extended support is 2020. So you will have completely support, patches and fixes until this time.
- Windows 8.1 end of extended support is 2023.
- For windows 7, end of mainstream support was January 2015. The end of mainstream support merely says that you wont get any more service packs or feature revamps. It means you will probably not get spartan on windows 7 and certainly not dx12.
Spot on "free update"
- Microsoft is offering free updates from windows 7 and windows 8 with the clear objective to push the installed base into Windows 10. There is no catch in here, you get your copy for free, as long as you are not using windows 7 or 8 enterprise editions and under certain OEM deals.
- You will pay for windows 10 upgrade if you choose to upgrade after the 1 year period post w10 launch. This, as i said, is an incentive to push windows 10 installs.
Licensing model
- Even if Microsoft would offer a "subscription model" there would be a traditional purchase mode too. Office is being offered in 365 subscription models that are very attractive in monetary terms, especially if you maintain a big installed base, but there are stand alone licenses too. With either models you end with installed software, the only difference is the license time.
- Currently enterprises can run windows agreements where you pay for a term and for the number of stations; in that way you are elligible to use the latest version of windows. Its a kind of subscription model, but all computers are locally installed.
Windows 8 isnt bad as most people say. I know the metro interface maybe somewhat of a problem, but personally i rarely use it, i just have my main icons on there plus i constantly use windows key + text to find functions and programs and just run. Under the hood, w8 is the same as w7 but with improvements. W10 will be basically w8.1 + desktop UI.
