I'm running Windows 7 64-bit in a VMWare Workstation virtual machine. My host is Windows Server 2008 64-bit SP2. I've enabled DirectX 9.0c acceleration in the W7 guest. When I try to rate the computer's performance I get the following message: ------------------------- [Window Title] Performance Information and Tools [Main Instruction] The Windows Experience Index for your system could not be computed. [Content] Could not measure storage performance. Unable to start the kernel logger. The logger is in use by another application. Please stop the kernel logger and try again. ------------------------- This is a fresh install and boot of Windows 7, nothing at all has been installed yet. What would be using the kernel logger? Googling the error turned up nothing, I wonder if this is a new bug.

Same problem here, with the same settings as mentioned above. Never seen this before in other windows 7 builds. How can we fix this?

Seeng that Directx is main actor in Performance evauation, maybe running DXDIAG from Start->Run will pointto Problem; for startersAlso could be something active that you are not aware of in Control Panel->Programs&Feaatures->"Turn Windows Features on or off" ( which is on left side of installed program list).

Matt - Got to ask... But is the version of VMWare Workstation you've got even up to date as far as handling Windows 7 as a guest? I'm thinking you might have more luck if you were running this under Virtual PC. Windows 7 comes with DirectX 11 - which is 2 generations newer than the one that came with XP. Engaging DirectX 9.0c may be hampering the process - which would likely be requiring DirectX 11 support.

Hi, Thank you for posting. Please perform a Clean Boot to check the issue. Clean boot ================= 1) Click the Start Button type "msconfig" (without quotation marks) in the Search box, and then press Enter. Note: If prompted, please click Continue on the User Account Control (UAC) window. 2) Click the "Services" tab, check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray). 3) Click the "Startup" tab, click "Disable All" and click "OK". Then, restart the computer. When the "System Configuration Utility" window appears, please check the "Don't show this message or launch the System Configuration Utility when Windows starts" box and click OK. NOTE: we can go back to normal boot by running msconfig again and checking on Normal Startup in the General tab. In the Clean Boot Environment, the third party services and applications are disabled, please check if you can finish the rating process. Hope this helps. Thanks.Nicholas Li - MSFT

Nicholas Li,Thanks for your answer. I did exact the same as you mentionted above but it didn't work for me. I got all the scores filled in exept the components: Graphics and Gaming Graphics. And again i got the followingerror message:-------------------------[Window Title]Performance Information and Tools[Main Instruction]The Windows Experience Index for your system could not be computed.[Content]Could not measure storage performance.Unable to start the kernel logger. The logger is in use by another application. Please stop the kernel logger and try again.-------------------------Thanks,Gijs Habets

Thanks for the tips, everyone. Running a Windows Update fixed the issue. It appears that acceleration isn't working as my graphics score is a 1.0, but at least the performance indexer does run.

I have the exact same issue. I have done the msconfig deal and it still did not rate my system. what is the kernal logger that it wants to be stopped?

I dont know if this is the case for everyone who got this error, but my windows 7 (professional 64 bit) was fully updated at the time and I noticed i had my 2 usb powered hard drives plugged in. Removed them straight away, re-ran the test and it worked...
