DXVer

DXVer is a lightweight and very easy to handle piece of software whose main purpose is to offer you the ability to quickly learn your current DirectX version, in just a few moves.
Determining your DirectX version can prove essential when you like to play games on your computer as well as for the proper functioning of various multimedia software, because it enables you to get the best performance out of your system.
DXVer does not require any knowledge in working with PCs and you do not need to perform any advanced operations in order to learn your DirectX version. At the same time, you do not even need to install it on your system, as it can run immediately after download, just by double-clicking it.
When you launch the application, DXVer will automatically detect the complete version number of DirectX on your computer, displaying it in full and including all the necessary details.
Moreover, the program can also detect your operating system version, along with its full name, service pack and internal build, which you can learn by hovering with your mouse over the 'Your OS' section, as the information is displayed in a tooltip.
DXVer determines if the DirectX version you currently have is the highest your operating system is capable of supporting or if you can update it to a newer issue. However, it will not offer you a download link, the ability to update it from the tool's interface, or other such options, so you will need to do that manually.
To summarize, DXVer is a simple and user-friendly utility providing you with an easy means of detecting your complete DirectX version and whether you need to update it, in just a few simple clicks of your mouse.
