How can I uninstall Directx 9?

To the best of my knowledge you can't. Once installed, it becomes part of the operating system. If you need to uninstall then a Google search for "DirectX Uninstall" returns several hits, but I can't speak for their quality. Ultimately, the approach I would try would be be to re-install the operating system and then not install DirectX 9.

Update: Check out this article: "A Cabinet file cannot be trusted" - Why? for pointers to several resources concerning that apparently common DirectX-related issue.

Hey Leo, I got a question about Direct X. I probably installed an illegal direct X 10 from a website and when I want to install XP Codec it says that I have to install Direct 7.0 or Higher??????? So, how can I delete this Direct X to install a new one from Microsoft official website??

It's me again, when I Run... "dxdiag" it appears Direct X 10 successfuly and I ran all the Direct X tests and all of them worked proparly. So I am not comfortable about it from XP Codec is telling me Direct X 7 or Higher and I got Direct X 10 so please answer ASAP.

leo...are you sure you can't downgrade directx 9.0c? cuz 9.0c is the crappiest piece of $#@! I have ever seen, cuz it can't play games that need 9.0 (such as GTA SA)

To completely and easily uninstall directX, you don't need to " re-install the operating system" .Even more,you do not have to delete it manually.
Try this tool:Perfect-Uninstaller.

You should never have to but if u get dinput or dinput 8 errors when trying to run a game do this

u most likely installed a keyboard or other hid usb device recintly that messed it up the key is to find out what one and uninstall all the old ones and new ones then reinstall so u have no old or currupt drivers my case was a keyboard on my friends computer

bill gates team offerd no help unless i pay an insane hourly fee my reply to that is get a real job and create things that work lol

i tryed all these sloppy geloppy answers that are no better then anything bill gates can create himself including direct x and his shi**y A$$ direct x tool in the run command

hey, this way of deleting is extremely UNSAFE for window XP as i tested, u cant re-install ANY directx after u deleted your main directx from HKEY_local_machine, don't try it if you don't know what are you doing.

I got an error message when I started Modern Warfare - World At War, stating there was an unrecoverable error with DIrectX. I'd previously played this game ok. I tried starting the game a few times, with the same error. Since that didn't work, I downloaded the latest version of DirectX (just in case). Tried to install it, but eceived message that it wouldn't install, as I already had the latest version. Fullishly, after checking on Google, I followed instructions to delete DirectX from my Registry (stupidly, I didn't make a copy first). No matter what I do, I can't install DirectX. I've even tried loading my XP disc, but get told my current operating system is newer ! Any suggestions ?
