Direct link to the Microsoft blog about it (from the article link in OP): World of Warcraft uses DirectX 12 running on Windows 7

Notably, it says the developers for each game have to develop a patch for their game, so it's not really a system wide thing. Furthermore, DirectX 12 was developed in sync with Win 10 so they are optimized for each other, therefore Win 7 can't do as well with DirectX 12 but it will be better than without it for a game that has been patched to use it.

Even if you could buy it as a consumer the costs on a per device level are astronomical

$50 year 1 : Jan 2020- Jan2021
$100 Year 2 : Jan 2021 - Jan 2022
$200 year 3: Jan 2022 - Jan 2023

Sure you 'could' pay them but why would you? You'd only be able to get to Jan 2023 and it'll cost $350. A Win10 Pro OEM license is $150.

Aside from it being free for Windows 7 Pro or 8.1 Pro users (you can upgrade to free from 8 Pro to 8.1 for free.) And its also free for any users of 7 or 8.1 (8.1 is a free upgrade to home users as well of 8.) (though you're going to get 10 Home.)

Also why would you. 10 restricts you alot compared to Windows 7, 10 also blocks alot of things that 7 ran and has alot of bloat and issues that 7 doesnt.

Edit: added 8.1 home, and added compared which is what I ment.

To still get support for the last usable version of Windows.
As for the prices, think they're halved for Enterprise? So if they'd decide to make it available for home users as well, it should be at worst the same as that for Ultimate, so those having that could get 1 year for $25, 2 for $75 and 3 for $175. I'd say too much even so for 3, but I'd likely get a 2 year extension for $75 if it'd be available.
Also, the price comparison should be against 8.1, which would grant people a 3-year extension of support, so the same as the full amount available for 7 for paying enterprise customers now, without handing over control of the system to MS or having system resources gobbled up by background processes at the same level as in 10. But 8.1 still is worse in some ways, and there's also the problem of adapting to something different vs. being able to keep using what you know, possibly a 3rd party start menu which may be paid as well, so there is justification for the extension for 7 to cost somewhat more than a license for 8.1 now. Comparing it with 10 is irrelevant; anyone willing to use 10 probably does so already.

Tbh its not worth it for 8/8.1. 8.1 is 10 just without certain things, it still acts like 10 as certain fixes for older games that are nedded for 10 are still needed for 8/8.1.

Its best to think of 8/8.1 as a 9.99

Main thing for me, you can still control when or if to install updates. You can also just get security updates and not the rest. And even if getting all updates, there will be no fundamental ones like the (typically) March and September new versions of Win 10 that keep everyone on their toes.
Second thing, less system resource use by the OS / background processes. Worse than 7, but still.
Third, as far as I know (but correct me if I'm wrong), no requirement to allow connections for even local functions, such as search, to work properly, unlike in 10.

Again its nonseniscal because you only get 3 years for nearly double the price of just buying a regular windows 10 license which you're going to have to buy anyway

Again the point is that using 10 is not an option. So it may be that you get more security holes patched before you do without security updates altogether and still stick to 7 (or 8.1), it may be that you give yourself more time to maybe get on Linux (with a Win 7 VM for games and any other programs without a Linux version or good/easy Wine compatibility)... May also be that it gives MS more time to release another usable Windows again, but good luck with that.

Thats not going to happen. If anything MS will jump to a new version and just call it Windows and it will use their new explorer and other things they are working on and break older things even more. Their goal is to create a totally cloud based system that doesnt need current architecture. They wanted to move only to UWP for example. That failed for now but something like that will happen and it will break everything older.

No probs there. Hey, XP is still a pretty damn good OS. If I had to build a legacy PC for retro gaming, it would definitely get built with XP Pro.

what? how long before hackers can make any dx12 game work on windows 7? lmao wtf is the point

Really interested what that mean, If they manage add full support, then maybe thru wine we will have full acceleration in virtual machine from linux. That is good news

Didn't they say at one point it wouldn't be possible to get DX12 on Win 7 to force people to upgrade? Oh, NOW they figured out how to add it.

End of Life for Win 7 is just planned obsolescence at it's finest. It's something the producer can force and will ANYTIME they get a chance to increase profits.

No that's the option. not wanting to use that is the problem. I fyou wanna spend $300 to stay on an obsolete OS for 3 years sure whatever. But call it what it is. Catastrophically dumb. If your magical 'plan' is to not take security updates in this day and age, you literally should just put your social security number and credit cards in the mail it ot the thieves directly

If the plan is 'to migrate to linux' then you know you can do that now instead of throwing money into a burning fire pit. Yes its called Windows 10
Are you magically expecting them to support every OS ever made forever?

Am I supposed to go to Sony and ask them to fix my Betamax recorder I bought 30 years ago?
