Knowing your computer’s specifications can help you understand its hardware, troubleshoot problems, check software requirements, and determine whether your PC can handle a particular application or game.
Windows provides several built-in ways to check important specifications such as the processor, RAM, Windows version, system type, storage, graphics card, and device information.
You do not necessarily need third-party software to find basic computer specifications. The methods below work with commonly used versions of Windows.
What Computer Specifications Can You Check?
Depending on the Windows tool you use, you can find information such as:
- Processor (CPU)
- Installed RAM
- Windows edition
- Windows version
- System type
- Computer name
- Device model
- Graphics card
- Storage drives
- Available storage space
- Network adapters
- Connected hardware
- BIOS information
Different Windows tools display different levels of detail, so you may need to use more than one method.
Method 1: Check Specifications in Windows Settings
The easiest way to view basic specifications is through Windows Settings.
Step 1: Open Settings
Press:
Windows + I
This opens the Windows Settings application.
Step 2: Open System
Select System from the Settings menu.

This is usually the quickest method for checking basic PC specifications.
Method 2: Use System Information
Windows also includes a more detailed tool called System Information.
Step 1: Open the Start Menu
Click the Start button or press the Windows key.
Step 2: Search for System Information
Type:
System Information
Open the application from the search results.
Step 3: Review System Summary
The System Summary section provides detailed information about your computer.
You can find information such as:
- Operating system
- System manufacturer
- System model
- Processor
- BIOS information
- Installed physical memory
- System type
- Available physical memory
- Windows directory
This method is particularly useful when you need more information than the standard Settings page provides.
Method 3: Check CPU and RAM Using Task Manager
Task Manager provides another convenient way to check some important specifications.
Step 1: Open Task Manager
Press:
Ctrl + Shift + Esc
Step 2: Select Performance
Click the Performance tab.
You can select different components from the left side.
For example:
CPU
This can show information about your processor, including its model and current utilization.
Memory
This shows information about installed RAM, including total memory and current usage.
Disk
This provides information about your storage device and current disk activity.
GPU
If supported, Task Manager can also display information about your graphics processor.
Task Manager is especially useful because it lets you see both hardware information and current resource usage.
Method 4: Check Your Graphics Card
If you specifically want to find your GPU, you can use Task Manager.
Open:
Task Manager → Performance → GPU
Windows can display information about the installed graphics processor.
You may see:
- GPU name
- GPU utilization
- Dedicated GPU memory
- Shared GPU memory
- Driver information
- Current GPU activity
This is useful when checking whether your computer meets the graphics requirements of software or games.
Method 5: Check Specifications Using DirectX Diagnostic Tool
Windows includes another tool called DirectX Diagnostic Tool, commonly known as DxDiag.
Step 1: Open Run
Press:
Windows + R
Step 2: Enter the Command
Type:
dxdiag
Then press Enter.
Step 3: Review the Information
The DirectX Diagnostic Tool can provide information about:
- System
- Processor
- Memory
- Windows version
- Display hardware
- Graphics drivers
- Sound devices
- Input devices
The Display tab is particularly useful when you need information about your graphics hardware and display drivers.
Method 6: Check Storage Specifications
To check your storage devices, open Windows Settings and go to the storage section.
You can see how much space is being used and how much remains available.
For more detailed drive information, you can also use Disk Management.
Press:
Windows + X → Disk Management
This can show your connected drives and partitions.
You can identify:
- Available drives
- Drive partitions
- Drive capacity
- File system information
- Unallocated space
Knowing your available storage is also useful when diagnosing performance problems.
For example, if your system drive is almost full, freeing up space may help address certain storage-related problems.
Method 7: Check Your Windows Version
If you need to know which Windows version you are running, press:
Windows + R
Type:
winver
Then press Enter.
A window will display information about your Windows version and build.
This is useful when checking whether your system meets the requirements for software, drivers, or troubleshooting instructions.
For a dedicated guide, see How to Check Your Windows Version.
Method 8: Check Computer Model
If you need your exact computer model, open System Information.
Look for:
System Manufacturer
and
System Model
This information can be useful when looking for:
- Manufacturer support
- Device drivers
- Hardware specifications
- BIOS updates
- Replacement components
- Troubleshooting information
Laptop users should keep their exact model information available when searching for manufacturer-specific support.
Method 9: Check Hardware Through Device Manager
Device Manager provides a list of hardware components detected by Windows.
To open it:
Press Windows + X → Device Manager
You can expand categories such as:
- Display adapters
- Network adapters
- Processors
- Disk drives
- Sound controllers
- Bluetooth
- Keyboards
- Mice
- USB controllers
Device Manager is particularly useful when diagnosing hardware or driver problems.
A warning symbol next to a device can indicate that Windows has detected a problem with that device or its driver.
Why Should You Check Your Computer Specifications?
Checking your specifications can be useful in many situations.
Before Installing Software
Some programs require a specific processor, amount of RAM, graphics hardware, or available storage.
Checking your specifications beforehand helps you determine whether your computer meets those requirements.
When Troubleshooting
Hardware information can help when diagnosing performance problems.
For example, knowing how much RAM your computer has can help you understand whether limited memory could contribute to slow performance.
When Upgrading Hardware
Before purchasing an upgrade, you should know what hardware is currently installed and whether the new component is compatible.
When Getting Technical Support
Support teams may ask for your:
- Computer model
- Windows version
- Processor
- RAM
- Graphics hardware
Having this information ready can make troubleshooting easier.
What Is the Difference Between Specifications and Performance?
Computer specifications describe the hardware and system configuration.
Performance describes how the computer is currently operating.
For example, a computer may have a powerful processor but still feel slow because of:
- High CPU usage
- Too many background applications
- Low available RAM
- Low storage space
- Software problems
- Windows issues
Therefore, checking specifications is useful, but it does not by itself explain every performance problem.
Quickest Ways to Check PC Specifications
If you only need basic information, use:
Settings → System → About
For more detailed system information, use:
Start → System Information
For current CPU, RAM, disk, and GPU information, use:
Ctrl + Shift + Esc → Performance
For graphics and driver information, use:
Windows + R → dxdiag
For Windows version information, use:
Windows + R → winver
Final Thoughts
Windows provides several built-in methods to check computer specifications without installing additional software.
For basic information, the Settings → System → About page is usually enough. For more detailed hardware information, System Information, Task Manager, Device Manager, and the DirectX Diagnostic Tool provide additional details.
Knowing your processor, RAM, storage, graphics hardware, Windows version, and computer model can be especially useful when installing software, upgrading hardware, or diagnosing computer problems.
