How to check Windows system information and specifications

One of the easiest ways to check Windows system information is by using the DxDiag tool. DxDiag, also known as the DirectX Diagnostic Tool, scans your computer and displays detailed information about your operating system, processor, memory, and BIOS. It also shows information about your graphics card, audio drivers, and DirectX version. By running DxDiag, you get a complete overview of your Windows computer hardware and driver setup in one place.

To check Windows system information without downloading third party apps, press the Windows key + R, type dxdiag, and press Enter. This opens the DirectX Diagnostic Tool, which is built into all modern versions of Windows. DxDiag not only lists core system details like Windows version and RAM but also diagnoses multimedia components such as GPU, sound card, and input devices. It is the most reliable tool for quickly understanding the specifications and performance readiness of your PC.
