DirectX is one of the essential software in running many games for Windows and some applications as well. This is why Microsoft fully embedded DirectX in every Windows installation in such a way that normal users cannot uninstall it. The problem with this move is that trouble can arise if external applications or viruses corrupt the DirectX files or settings. Although the latest setup file is freely available from Microsoft’s website, reinstalling DirectX doesn’t always fix the problem. The good news is that you can uninstall DirectX through workarounds. Here’s how you can do that.
Obtain the Latest DirectX Version First
The purpose of uninstalling DirectX is not to save space or simply leave it removed as many problems can arise. Instead, a reinstallation should follow immediately after DirectX is installed so be sure you have the DirectX setup file with you. DirectX usually comes bundled with many games, but it is better to download the latest version of DirectX to be sure.
Try to Reinstall DirectX Anyway
Repairing DirectX by means of uninstalling and then reinstalling should be your last resort because of the risk involved. Before you do that, try to at least run the DirectX setup program and see if it can fix the problem. Some DirectX problems can be repaired with this method without any risk of losing critical data.
Method 1: The System Restore Method
Both Windows XP and Windows Vista have a built-in system tool called “System Restore”. This utility is useful for taking your computer back to a previous state where everything was running fine. This includes your DirectX as well so you may have success with this method. This method counts as an uninstall because all your present DirectX settings are removed and then replaced with your old configuration. For best results, try to recall the last time your system was working and restore it to the latest point possible. Restoring very old points may cause problems depending on your system.
Method 2: Using a 3rd Party Application
There is one useful shareware application that allows users to safely uninstall DirectX called “DirectX Happy Uninstall”. This utility can effectively backup your current DirectX installation to minimize the risks of uninstalling DirectX. In addition, users have the option either to remove DirectX or rollback to a previous version. This program has been widely tested by people and has proven to work. The only drawback is that this application isn’t free. Getting this software can be worth the investment if you don’t want to format your computer to solve the problem.
Method 3: Manual Removal
If you dislike the above methods, you can force Windows XP to install DirectX 8.1 by clicking the Start menu and then going to “Run” and type “regedit” to launch the registry editor. After launching, browse to this key: HKEY_LOCAL_MACHINESoftwareMicrosoftDirectX and delete it. Restart your computer and your computer should install a fresh copy of the old version. From there you can install the latest version. This method only works with Windows XP.
It is rare for major DirectX problems to arise especially if you keep your XP or Vista operating system updated. The safest methods to go for are Methods 2 and 3. Otherwise you can try reinstalling your OS.
