After installing Windows 10 Technical Preview (a clean install) pretty much 99% of my games stopped working. Most of these I got on Steam, so when I try to play one, it starts the first-time setup, where it tries to install DirectX and then it just returns to desktop. If I try again, it just does the same, but if it's one of the few games which don't install it when running them the first time (i.e., Binding of Isaac), then it has no problems.
After that, I tried to play a couple of relatively new games I got from GoG, but they gave me error messages when trying to install DirectX. They still install, but if I try to play them they don't run because they can't find DirectX-related dlls in the computer.
According to Dxdiag, though, DirectX 11 is installed. Reading forums, it seems to me that most people can play games with no problem with the Tech Preview, but some can't because Windows 10 doesn't recognize their graphic cards, and they have to switch to integrated graphics. I can't do this, as my motherboard doesn't have them, but at least when checking system information it seems that the OS recognizes the card (a Radeon Hd 4870, not exactly cutting edge stuff...), so not sure if it's the same, though it might be, as I tried installing the latest drivers for Windows 7/8 and couldn't. Has anybody had similar problems? And did anyone manage to solve them, and how?

Hope this helps. Let us know if you have any other issues with Windows in future.
I installed Windows 10 release version and all my games too stopped working. Most of the games fail with an error message "Failed to create D3D device". Rest of the games just stop working (most probably due to the same reason).
I have been testing Windows 10 on my son's computer and he has the same issues - Garry's Mod and ARK:Survival Evolved both continually ask for Direct X to be installed. I thought DX was supposed to be backwards compatible - surely the programs should see that DX 12 > 9 and therefore it should run?
Very aggravating and Microsoft will have a lot of very upset customers if half or more of their Steam collection has been rendered useless due to a Windows 10 upgrade!
Hi BenjaminWI,
I also have this problem in windows 10 insider preview build 10162. All my game give me error like
d3dx9_36.dll is missing. To fix this problem dowload DLL Files Fixer from torrent here >http://kat.cr/dll-files-fixer-3-0-81-2643-final-ml-retail-crack-scenedl-pimprg-t8131363.html . After you install and cracked it or whatever. Run the software and click on "Install DLL files" tab next to "Status". Then open your game see the error code for example:
d3dx9_36.dll , type this in the search bar then click on the search result it will download and install it. Now open your game. See all works for me. Good luck!
I have the same problem with Steam Games, I can't even play a youtube using chrome (IE is fine) video because my computer freezes and I have to turn it off, I had played a few days ago in Windows 10 and I didn't have any problems, I tried again today and is completely unplayable. I have both my graphics card and my directx up to date. Almost error messages are related with direct3d and things like those.
