How to Hack the Windows Experience Index
When you look at the Windows Experience Index (WEI), you see certain information about your PC. Have you ever wondered how you can increase the numbers without PC maintenance or purchase of a new PC? This article will detail a hack the WEI and indicate any desired numbers.
The reasons for doing this involve the Windows Experience Index API. The API in the WEI is used to enable the functionality of various programs. If the score is low, there will be impaired functionality of some sectors of a given program or the program could be completely disabled. This obviously can pose some problems. Basically this hack tricks your operating system to enable you to use features.
The XML File Hack
This method is a little advanced, as it does require at least basic knowledge of XML files. Just stick to these instructions and you will make it through. Before proceeding, please create a System Restore point.
Begin by navigating to C:\Windows\Performance\WinSAT\DataStore.
Open a file ending with Formal.Assessment (Initial).WinSAT. There may be more than one file like this. If so, check the file dates and use the most current file. Right-click the file and select edit to open the file in the notepad. Click on the Edit menu and then click find in the dropdown menu. A dialog box will open. Type ‹WinSPR› in the dialog box. Click â€œFind Nextâ€.
Notepad highlights where the code starts. This is the code that will be edited. Any WEI values can be edited. The following list shows what tags edit certain values. For this demonstration, the tags you are looking for are the ones that follow the WinSPR tag.
- SystemScore tags change the overall rating
- MemoryScroe tags change the Memory rating
- CpuScore tags change the Processor rating
- GraphicsScore tags change the Graphics rating
- GamingScore tags change the Gaming Graphics rating
- DiskScore tags change the Primary hard disk rating
Feel free to change any of the given values. The next step is to save the file without renaming it. Save it to the Desktop. Cut the file from the desktop and paste it in the following location:
C:\Windows\Performance\WinSAT\DataStore. Select Move and Replace in the window.
You will then be prompted for administrator permission. Click â€œContinueâ€ and you will be prompted to provide a password if you are not already logged on as the administrator. Now go back to the Windows Experience Index and notice the changes.
This method is somewhat advanced. There is a free program available that will do this work for you. It is called WEI editor and you can download it from this link:
Download and install the program. You will need Admin privileges to run the program. After installation, a simple GUI is presented
All you have to do is enter the numbers as you see fit. The range is from 1 to 7.9. Change one or more of the values. You can change all of them if you wish, keeping in mind that the overall system rating is based on the lowest score. To make changes in the future, the program can be found in the Downloads folder in Windows 7 and will be titled â€œexperience_index_editor.exe.
To reset WEI true values, open WEI and click â€œRe-run the assessmentâ€. This may seem like it would improve system performance, but it will not. All this will do is enable additional functionality.Advertisement
What sort of functionality will be enabled?
I found this Dean which might explain it, not sure though: http://windows.microsoft.com/en-US/windows7/What-is-the-Windows-Experience-Index
The API in the WEI is used to enable the functionality of various programs. If the score is low, there will be impaired functionality of some sectors of a given program or the program could be completely disabled. This obviously can pose some problems.

I have never heared of software being (partly) disabled on basis of this score.
But lets say some software does this: why would you want to hack it if it did?
For example: a game might load giant textures because you score a 7,9 on the RAM part (meaning you have 12GB+ RAM or so) but in reality you only have 4GB.
Hacking the score will have an adverse effect on your system performance because your ram cant handle the giant texture resulting in low FPS…
I guess this is just to show off then?
I’d also say it is more for showing off. Then again, if your system scores 4.9 and you need 5.0 for a functionality, you might want to hack the score to enable it.
What to type in the dialog box?

Sorry, the blog hid some chars, I have corrected it now.
This is useful for those who still want to enable Aero after they got a WEI Graphics score of below 3.
