Calculate your WEI (Windows Experience Index) under Windows 8.1
Sponsored By
I used to be slightly obsessed with getting a high "WEI" in Windows. The Windows Experience Index was a number meant to give you an idea of how strong your PC was. The idea would be that you'd go get a game at the store and it would say "WEI 5 or greater" and you'd say, "oh, I have a 6, so this game will run great."
Under Windows 7 the maximum WEI was a 7.9, so I, of course, set off to build a machine that got a perfect 7.9 WEI.
In Windows 8 and 8.1, however, the friendly UI for showing your WEI is gone.
However, you can still get the RAW numbers in Windows 8.1, I'm told from a tipster who emailed me. (Thanks!)
First, run a cmd.exe prompt run "winsat prepop." If it fails to generate much output, try "winsat formal."
Then, open a Powershell command prompt and run "Get-WmiObject -class Win32_WinSAT" and you'll see all your scores!
Looks like this machine is limited only by the SSD, but otherwise is an 8 class machine! I'm happy to be able to confirm my WEI again!
Does anyone know if Windows 8.1 maxes out at 8.9 or 9.9 WEI? Sound off in the comments!

Just thought I note that since the "overall" WEI was just the lowest number of the bunch you can just do that manually to find your "overall" WEI yourself.

Well, it was 9.9 in Windows 8 if I'm not mistaken so I doubt it has changed with 8.1.
Also, I wonder if there's an official reason for the removal of WEI. I'm not that bothered by its absence but it would be interesting to know.

A 9.9 seems unlikely with any modern hardware. I have nearly top end hardware in my gaming PC (including RAID-0 SSDs and a GeForce 780 Ti) and not a single score gets above an 8.5.
Neat! Just ran it for my work laptop and got 7.2 for graphics and D3D, and 8.1 for CPU, disk and memory. Pretty happy with that!

I got 0 (Zero) for CPUScore, D3DScore, DiskScore, GraphicsScore, MemoryScore, WinSPRLevel. :( By the way i got 3 for WinSATAssessmentState.
Can you please explain why i got these abysmal scores?

Try with "winsat formal". Then check result WinSAT.xml files at C:\Windows\Performance\WinSAT\DataStore.
If created successfully, type "Get-WmiObject -class Win32_WinSAT" in PowerShell commandline.

Using linqpad to get results in C# - hit F4 to add System.Management dll and namespace
Could also add a process call to run the "winsat prepop" command.
void Main()
{
var query = new SelectQuery("Win32_WinSAT");
var searcher = new ManagementObjectSearcher(query);
foreach (ManagementObject m in searcher.Get())
{
m.Dump();
}
}
Could also add a process call to run the "winsat prepop" command.
It's no wonder why this didn't catch on. What ordinary person is going to run a "black box" that spits out a 7.9 and feel like it's useful?
I was thinking about how this could be improved - maybe calculate the number as a 1-10 rating, using the Windows version as a quantifier (I hope I'm using the term correctly). Something like: Win7:8 WEI, Win8.1:7 WEI
Anyway, it makes me feel pretty good that my 3yo refurbished Dell E6510 still does ok; probably because of the upgraded SSD:

The question that no one asked including Scott is Why did they take out the WEI UI.
@Abdu They probably took it out for a few reasons:
- The numbers are largely meaningless anyway.
- The shift towards smaller, lowered powered devices means your brand new tablet might get poor scores. Obviously, not good optics.
Scott, you surely must be the WEI's biggest fan. Does the WEI team send you a cake for your birthday or what?

a *possible* explanation on the 'all scores 0' is the "boot from VHD".
I've configured 2 different systems to have easy multiboot with this technique (virtual file being VHD or VHDX), and summarize hereafter my "no joy experience":
-on Windows 8, when running WinSAT prepop then the Get-WMIObject, got all 0.
-on Windows 8, when running WinSAT formal, no XML file created in 'C:\Windows\Performance\WinSAT\DataStore'
-on Windows 8, in Control Panel/Performance Information & Tools, the "Rate this computer" executes all tests, BUT in the end displays "the WEI could not be computed. Could not measure storage performance. The disk cannot be accurately assessed while the system is booted from a Virtual Hard Disk". Close. :-(.
-on Windows 8.1 with update, got all 0, and no XML file either.

Someone please try this on a surface and maybe just maybe you will find out why it was yanked out.
Just tried this out on my Surface RT, but the winsat commands didn't produce any output at all. I could run the WMI command, but all the values were zero.
The UI is in Windows 8 it was only removed in 8.1. I don't think it was ever in RT code base, no reason to port it and probably the numbers wouldn't be comparable considering platform differences (CPU/GPU).
