Windows experience index wei

The Windows Experience Index (WEI) provides a standardized way to measure your system’s performance capabilities. You can access this diagnostic tool to evaluate processor speed, memory, graphics and disk performance through several methods.

What is the Windows Experience Index (WEI)?

What are Windows Experience Index scores? These scores evaluate your computer’s hardware and software configuration on a scale from 1.0 to 9.9. System administrators use these diagnostic benchmarks to evaluate whether workstations meet application requirements or need hardware upgrades.

Microsoft designed this automated assessment tool to eliminate guesswork when matching system capabilities to software requirements. Before WEI, organizations often discovered compatibility issues only after software deployment. The standardized scoring system helps you make data-driven decisions about hardware allocation and upgrades based on quantifiable metrics rather than assumptions about system performance.

How to find my Windows Experience Index score

Windows offers multiple built-in pathways to access your WEI score. Here are a few.

Built-in access methods

When Microsoft launched Windows 8.1, they removed the graphical interface for the Windows Experience Index, a change that surprised many system administrators. Yet this valuable diagnostic tool remains accessible through command-line interfaces. While the assessment process has evolved, it continues to provide valuable performance metrics for system evaluation.

For Windows 8.1 and later versions, you can access WEI scores through PowerShell or Command Prompt. Here’s how:

1. Press “Windows key + X” or right-click the Start button.
2. Select Windows PowerShell (Admin) or Command Prompt (Admin).
3. Type winsat formal to run a new assessment.
4. Once complete, use one of these commands to view the results:
   • Type winsat prepop
   • Or view files directly at: C:\Windows\Performance\WinSAT\DataStore

For a more detailed component analysis, you can use PowerShell:

1. Open PowerShell as administrator.
2. Enter: Get-WmiObject Win32_WinSAT

Third-party tools

Third-party applications offer enhanced WEI assessment capabilities beyond the standard Windows tools:

• ChrisPC Win Experience Index rebuilds the original Windows interface and provides detailed hardware analysis with export options for your assessment results.
• PassMark Performance Test includes the WEI measurement along with additional benchmarking tools that help you compare scores across different systems in your organization.
• Novabench incorporates WEI-style scoring while adding cross-platform compatibility and cloud result storage that enables you to track performance changes over time.

Understanding the Windows Experience Index ratings

The WEI rating system provides a comprehensive evaluation of your system’s performance capabilities. Each assessment generates both individual component scores and a base system score that reflects your overall performance level.

Score breakdown structure

The Windows Experience Index evaluates five major components independently. Your base score reflects the lowest-performing component rather than an average. For example, if your system scores 8.5 in processor speed but 6.2 in graphics performance, your base score becomes 6.2. This structure helps identify performance bottlenecks that might affect system operations.

Component assessment scales

Each hardware component receives a score between 1.0 and 9.9. The processor assessment measures calculations per second and manages threads efficiently. Memory operations are evaluated based on RAM speed and data throughput. Graphics tests measure both the performance of the Windows interfacand 3D rendering capabilities. Finally, the disk score assesses the read/write speeds and access times for your primary storage device.

Performance thresholds

Microsoft established specific thresholds that correspond to different performance levels:

• Scores below 4.0 indicate basic functionality suitable for standard office applications and web browsing.
• Mid-range scores between 4.0 and 6.9 support intermediate tasks like multimedia applications and basic data analysis tools.
• High-performance ratings above 7.0 demonstrate capability for advanced applications such as video editing, complex database operations and visualization software.

These thresholds help system administrators determine whether workstations meet specific software requirements. They also provide valuable insights for guiding upgrade decisions and help identify which components limit system performance. By leveraging these ratings, technical teams can make informed decisions about hardware allocation and prioritize system improvements effectively.

Methods to improve your WEI scores

Your WEI assessment results point to specific ways you can enhance system performance through targeted upgrades and optimizations. Understanding these improvement methods helps you maximize your technology investments.

Hardware upgrade paths

System memory upgrades often provide the most cost-effective performance boost. Adding RAM or replacing existing modules with higher-speed alternatives improves multitasking capabilities. Storage upgrades to solid-state drives also deliver significant improvements to disk performance scores. In turn, graphics card replacements enhance both desktop interface responsiveness and 3D rendering capabilities. Finally, processor upgrades typically require more extensive system changes but can dramatically improve computational performance.

System optimization steps

Regular maintenance practices help maintain optimal WEI scores. For instance, removing unnecessary startup programs can help reduce system overhead. Likewise, updating your device drivers makes sure hardware components operate at peak efficiency. You can also adjust your Windows power settings to prioritize performance over energy savings when needed. Additionally, scheduling regular disk defragmentation for traditional hard drives or enabling TRIM support for solid-state drives can further optimize storage performance.

Performance bottlenecks

System bottlenecks arise when a single component limits overall performance. For example, pairing a powerful processor with insufficient RAM can create memory bottlenecks and slow down application performance. Similarly, graphics-intensive applications require both adequate GPU power and PCIe bandwidth to work properly. These storage bottlenecks emerge when high-performance processors are forced to wait for data from slower hard drives. Likewise, applications that rely on remote resources can affect system responsiveness.

Address bottlenecks systematically by:

• Monitoring resource usage patterns to identify constrained components.
• Evaluating the cost-benefit ratio of potential upgrades against performance requirements.
• Considering interdependencies between components when planning system improvements.

Practical applications of WEI scores

WEI scores serve as a standardized tool for system administrators to make informed decisions about hardware deployment and upgrades. These metrics provide objective data for planning and maintenance tasks across your organization.

System requirements analysis

These scores simplify software deployment planning by providing clear metrics on hardware capabilities. By comparing application requirements with current system scores, administrators can identify compatible workstations and prevent productivity disruptions from failed software installations. Use these scores to create hardware profiles that match specific business applications, ensuring users have appropriate resources for their tasks.

Hardware compatibility checks

Before purchasing new hardware components, review your WEI subscores to understand your upgrade requirements. These assessments reveal whether existing systems can support the capabilities of the new hardware. For instance, memory upgrades must align with both speed ratings and motherboard specifications. Graphics card upgrades require adequate power supply capacity and PCIe slot compatibility. Similarly, storage upgrades must account for interface standards and system drive configurations.

You need to take into account all of these variables before making any upgrades or major financial investments.

Performance benchmarks

WEI benchmarks provide baseline performance metrics for your systems, serving as a foundation for monitoring and optimization. Regularly tracking these scores helps identify hardware degradation early, preventing potential impacts on productivity. By monitoring scores across departments, you can allocate resources more effectively to align with your business needs. Additionally, comparing benchmark results between similar systems allows you to detect and address abnormal performance variations promptly.

Use WEI benchmarks to:

• Document system performance changes after hardware or software modifications.
• Compare actual performance metrics against vendor specifications when evaluating new equipment.
• Create standardized hardware profiles for different user roles within your organization.

These practical applications help technical teams optimize system resources and plan future upgrades. The standardized scoring system enables consistent evaluation across different hardware configurations and Windows versions. When combined with other diagnostic tools, WEI scores provide valuable data points for maintaining and improving system performance throughout your technology infrastructure.

The good news is you don’t have to explore the Control Panel to find your computer specifications. Instead, you can rely on the score ratings of the built-in diagnostic tool, Windows Experience Index.

In this guide, we’ll show you different ways to check WEI diagnostic reports and determine your PC’s overall performance.

What Is Windows Experience Index (WEI)?

Microsoft developed the feature as part of the Windows System Assessment Tool (WinSAT) to enable users to evaluate and monitor their hardware performance.

More specifically, it uses a number-based rating system (ranging from 1.0-9.9) to qualify the working condition of the five main components of your PC. They are the CPU, RAM, graphic characteristics (2D and 3D), and ROM.

They are also called sub-scores and base scores. Usually, the lowest value represents the overall rating of the system itself, meaning that PCs with a high rating have high computing power.

You can follow the guides below to determine your Windows 10 system performance rating via the Windows Experience Index.

How to View the Windows Experience Index Score on Windows 10

The process is straightforward. All you have to do is run the WEI tool once after updating it in the Command Prompt.

After that, use any of the three methods discussed below to check the reports.

Updating the WEI Score in Command Prompt

1. First, delete all XML files in the destination folder below:

C:\Windows\Performance\WinSAT\DataStore

1. Use the Windows + X shortcut to open the Quick Link menu and select the Command Prompt (Admin) option.
2. Type “winsat formal” (no quotes) in the Command Prompt and hit the Enter key to start the diagnostic test.

Now, you can check the WEI score using the following procedure:

1. View the WEI Score Under System Diagnostics

1. Press the Windows + R keys simultaneously to launch the Run dialog box.
2. Type “perfmon” (no quotes) in the box and click Ok to open the Performance Monitor.
3. Click the drop-down icon on the left pane and expand the following folders:

Reports > System > System Diagnostics.

1. Under the System Diagnostics folder, find the recent XML file according to the date on your computer.
2. Open the report and navigate Hardware Configuration > Desktop Rating > Query > Returned Objects.
3. Now, you should see the test details displayed showing the WEI value for CPUScore, D3DScore, DiskScore, GraphicsScore, and MemoryScore.

2.  View the WEI Score via File Explorer

1. Use the Windows + E shortcut to open the File Explorer window.
2. Paste the following path in the address bar and tap the Enter button:

%windir%\Performance\WinSAT\DataStore

1. Double-click the Formal.Assessment (Recent).WinSAT.xml file. It is the one with the most recent date.
2. Now, scroll down to find the section with the <WinSPR> tag as the header. There, you will see the various subscores. Note: the SystemScore on the list represents the Base score.

If there are no Formal Assessment files under the DataStore folder, generate them using the Command Prompt. We have discussed the method above.

3. View the WEI Score in Windows PowerShell

Most PC users favor this approach because it is easier. It also generates the reports in less time compared to the previous methods.

1. First, open the Quick Link menu using the Windows + X shortcut.
2. Select the PowerShell (Admin) option and hit Enter.
3. Copy and paste the command line below in the PowerShell and click Ok:

Get-CimInstance Win32_WinSat

• After that, the subscore ratings will appear instantly. (Note that the WinSPRLevel rating represents the overall system rating).

Note: If you are a gamer or a heavy PC user, running resource-intensive applications on a system rated 7 or below might lead to a fatal system crash.

That’s why it’s advisable you apply the necessary measures to increase the ratings. You can achieve that by replacing the specific hardware components with low subscores. Or, you can use Auslogics BoostSpeed to optimize and resolve issues affecting the system.

Auslogics BoostSpeed helps set up automatic memory and processor management, which reserves sufficient space and processing power for running applications on your computer. That way, you can expect a consistently smooth and enjoyable user experience.
