DirectX is a set of libraries and software tools that are used to solve problems related to the release of applications and games for the Windows operating system. Each OS version has a certain generation of this software installed, which corresponds to the capabilities of the installed video card. Each subsequent release of the API package includes all legacy libraries, so you don't have to install all the releases in a row - just install the latest package. Let's see how you can check DirectX on Windows 7 in different ways.
Standard means
Windows operating systems have a special built-in feature that allows you to view information about the system, screen, sound and input devices. You can access this application in two ways: using a command in the Run window or by launching an executable file. Let's consider both options.
In order to check DirectX on Windows 7, you need to follow these steps:
- Launch the Run application. This can be done using the Start menu and the item of the same name in it, or through the Win+R key combination.
- In the window that opens, enter the dxdiag command and click OK to launch the desired application.
- After some time spent collecting information, you will see a window with statistics and
- On the first tab "System" there is a line "DirectX Version". Opposite it you will see the number of the current software version that is installed on the computer.
- However, the version that appears in the first tab is not necessarily the one supported by your video card. To find information about supported libraries, you need to open the Display tab.
- Pay attention to the "Drivers" section and the DDI line for Direct3D. Opposite this item is the generation number of the API package that is supported by your video card.
Now you know how to check DirectX on Windows 7 in two directions - the one that is installed on the computer, and the one that is supported by the graphics accelerator of your computer.
Second standard option
You can launch it in other ways. First, you can open the system partition of your hard drive and go to the Windows and System32 directory. In the list of all files, find dxdiag.exe and open it.
Secondly, the user can use the search in the Start menu. To do this, open the menu and enter the name of the executive file. Once it appears in the list of matches found, run it. By all means, you can run the application and check the DirectX version on Windows 7. Also, the described options are suitable for all subsequent versions of the operating system, up to 10.
Third party programs
If you are not satisfied with the standard checking tool, then you can use a third-party utility to check information about the system and hardware. For example, one of such programs is the popular AIDA64. You can download a free trial version and see the DirectX version on Windows 7 through it.
You need to run the program and select “Operating system” in the main directory with partitions. In it, find the line with the name of the software, opposite which the installed version will be written.
To understand which version is supported by your video card, find the DirectX section and open the "Video" tab. Then find the line "Hardware support". Opposite it, you can check DirectX on Windows 7, which is supported by your graphics accelerator.
Active users who often play various games come across such a program as DirectX. If anyone else doesn’t know what this is or why it is needed, let’s try to briefly explain. This is a developed set of software library files for the normal operation of games on a computer. Simply put, this is a program without which games will not launch or will simply freeze. At best, without Direct X, games will simply slow down, but this will not bring any pleasure. Avid players know that almost every game on the disc usually comes with the current version of DirectX, without which the game simply will not work. Naturally, when installing any game, you need to take into account the presence of supported DirectX on the computer.
How to view the DirectX version
In fact, it is very easy to find out which version of the API libraries is installed on your computer.
- In the Windows search bar, write the command - dxdiag.
- Open the utility.
This is a small diagnostic utilityDirectXand version checks.
In the program window mswe can see all the information about the system. Current installed edition, paging file, amount of RAM, system version and bit depth, and BIOS firmware.
How to find out DirectX on Windows 7
- Besides, there is another way how to find out the version of DirectX , To do this you need to launch the classic application "Run".
- There are several ways to do this. In Windows 7 it is located in the " Start" Or use a keyboard shortcut WinKey+R (for any operating systems of the Windows family).
WinKey - this is the home key, usually marked with a logoWindows.
- In the application window that opens, enter the command to launch DirectX diagnostics.
Windows 10 version check DirectX
You can also find out which DirectX is installed on the system through the command line console. There are many ways to launch it. In the latest versions of Windows 10, for example, the easiest way to do this is through the “ Start", on which you need to right-click and select from the list Windows PowerShell . Then enter our treasured command in the console to launch the DirectX diagnostic utility.
We look at DirectX in Windows 8
Command to run diagnostics dxdiag On Windows 8 operating systems you can open it in the following way:
- Go to the start screen, then click on the down arrow to open the list of all applications, and here in the search bar we write our command.
You can also check the release using third-party software, for example, using the AIDA64 or Everest program. Both programs are from the same developer and are almost identical. Of all the possible functions and capabilities that they have, you can also see what version of DirectX is installed on your computer.

The Windows operating system has a rather complex structure, which only its developers can understand. For proper operation of all its components in applications and games that require serious resources, developers from the Microsoft studio release a special set of tools - DirectX. It is a mistake to think that this is just a program that users need.
In fact, DirectX is a set of tools that is supported by Microsoft for developers. It is impossible to program complex applications and games for Windows without DirectX. It must also be installed on the end user's computer of the developed program or game so that Windows can interact with it. DirectX tools are regularly improved and new versions are released. That is why it is important for the user to know which DirectX is installed on the computer, and whether it needs to be updated to work with a modern game.
How to find out which DirectX is installed
Determining the version of DirectX on a computer running Windows is very simple; for this you need to:
- Press the Windows + R combination on your keyboard to open the “Run” line;
- You will need to enter the dxdiag command in it;
- This will open a system information window called “DirectX Diagnostic Tools”. On the “System” tab at the bottom you can see a column indicating which DirectX is installed on the computer.
Important: You can install any version of DirectX on your computer. However, there is an important nuance: if it is not supported by hardware, then the Windows system will not be able to work with it. Then the operating system selects the highest supported version of DirectX as active, and it is this version that is displayed in the diagnostic menu, information about which is given above.
How to determine DirectX version using third-party programs
In addition to the utilities built into the operating system, third-party applications allow you to determine the DirectX version on your computer. At the same time, they are able to provide much more information than the dxdiag command mentioned above.
A convenient computer diagnostic tool is the AIDA64 application. Its free version can be downloaded from the official developer website. This program allows you to find out information about all computer components, as well as about the software component.
In the left menu of the application you can see a separate DirectX item. It contains information in three subsections: files, video, sound:
AIDA64 is not the only diagnostic program for your computer. You can find many of its analogues on the Internet, both paid and free.
Why DirectX 12 does not work on Windows 10
One of the features of the Windows 10 operating system, which Microsoft is actively promoting, is games. The new version of the operating system at a “close to hardware level” works with games that are developed on DirectX 12. This allows players on low-power computers to run projects that require high performance.
However, some Windows 10 users may discover when checking that they have DirectX 11 or 11.2 installed, and not the modern DirectX 12. In such a situation, there is no need to download DirectX 12 from the official Microsoft website and install it on your computer, since this will not help. This version of drivers is natively available in Windows 10, and the solution to the problem should be sought in another plane.
If you see DirectX 11.2 instead of DirectX 12 on Windows 10, this is due to:
It is important to note that a more recent DirectX on a computer does not replace previous versions. That is, if an application or game requires DirectX 8,9 or 10 to run, and later versions are installed on your computer, you must download the “old” driver.
First, let's define what DirectX is. This is a package of multimedia technologies necessary to run multimedia applications and games on a computer or laptop.
Often, in order for a game to launch, it is necessary to update the version of Direct.
In most cases, many toys installed on a modern device are accompanied by the current Direct package, but if it was not detected, then you need to independently see what the latest version was installed on the operating system.
Updating the package helps achieve better graphics in computer games, provided that a powerful video card is installed on the PC.
That is, for example, a game requires DirectX 9, and a person will install version 10, and at the same time, the video card will be weak, and significant changes will not be visible.
The instructions below for checking the installed version of DirectX will work for the Windows 7 operating system.
Using the DirectX Diagnostic Tool
First, you need to click on the “Start” button in the lower left corner of the screen, and there, in the “Search files and programs” field, enter a query such as dxdiag.
After the command has been entered, you must press the “Enter” key on your keyboard.
Next, a special window will open in which a person can easily see the installed version of DirectX on the PC in the “System” tab. 
Using auxiliary software
Traditional verification methods are not suitable for all people; some people like to verify the results using special utilities. And for this reason, a program such as Astra32 is often suitable for checking the DirectX version.
This software is distributed free of charge, and on the official resource it is possible to download Portable (version that does not require installation). After launching this software on your computer, scanning the system begins. After the scanning comes to an end, on the main screen, in the very first window, you can find out the installed DirectX on your PC.
The scan takes about a minute and the result will be displayed in the main window.
There are times when people do not need to view the installed version, but completely remove the direct from their PC.
You can completely remove this component from your computer using such current programs as “DirectX Killer” or “DirectX Happy Uninstall”. The named utilities do not have much functionality, but they cope with the main task one hundred percent.
Now, you don’t need to spend a long time figuring out why a purchased game with a system error may not launch; just read the information presented in this article to find out about the need to use Direct.
Now, anyone can learn how to correctly check which directive is installed on a working PC. In addition to the Windows 7 operating system, you can easily find out Direct X on other versions of Windows (XP, 10, and so on).
What is DirectX? This is a set of APIs needed to solve problems related to programming in the operating version of Windows. It is most often used when writing games, so often newly released games can only work under new versions of DirectX. Today I will talk about how to find out which version is installed on your PC or laptop.
First method
To begin, we will use the standard component diagnostic tool, which is built into Windows. To do this, you need to use a utility called “Run” (Start - Run, or Win + R). In the window that opens, enter the word dxdiag and click OK.
A window will appear in which you can not only see the version of DirectX installed, but also a number of other parameters, including computer name, model, manufacturer, memory size, and so on.
Second method
If for some reason you cannot use the method indicated above, you can use third-party utilities. There are a great many such programs, take at least the legendary EVEREST, which shows absolutely all the information about your computer.
You need to install the program, then run it and wait until the system collects the necessary information. Go to the “Computer” - “Summary Information” section and all the information will be displayed on the screen, including DirectX (see screenshot). In my case, the program is in English, but I highlighted the main points.
By the way, do not forget to update DirectX as it is released, so that you will always be able to play modern games.
