Hi, When running WEI, i get the following error.... The Windows Experience Index for your system could not be computed. Cannot complete assessment. The assessment or other operation did not complete successfully. This is due to an error being reported from the operating system, driver, or other component. ive checked Device manager, and all drivers are up to date. i also did a reinstall of everything but still no joy. it just wont rate anything.! System is :- MSI P43 NeoF C2D E6300 1.86Ghz 4GB (4 x 1BG) Corsair XMS2 DDR2 Nvidia 7900GS (Driver 191.07 but ive tried ealrier and a later beta too.) Windows 7 Home premium Full retail release. (Build 7600) Anyone any ideas??? Cheers Ross.

Hi, You may also update the BIOS and perform the following steps to check the issue. Verify the UxSms service status ====================== 1. Click on the Start Button, type "services.msc" (without quotation marks) in the Start Search box and press Enter. (Click "Continue" if User Account Control prompts for permission) 2. Double click the service "Desktop Windows Manager Session Manager". 3. Click on the "General" tab; make sure the "Startup type" is "Automatic" and the "Service status" is "Started". If not, please select "Automatic" from the drop down menu and click the "Start" button to start the service. 4. Click OK. After that, you can test the issue in Clean Boot. Good luck!Arthur Li - MSFT

Hi, thanks, for the reply, i tried all that above, installed live update from MSI and i reinstalled the latest bios, Desktop Windows Manager Session Manager was already staterew, did a clean boot, no services running, but it still wouldnt do the WEI, still say cant compute. Cheers Ross.

Update all drivers:especially for chipset,video card,network card.If you have installed KIS 2010 then surly this soft is responsible for this issue http://forum.kaspersky.com/index.php?showtopic=141252 uninstall it.Possibly another 3p security software can cause this issue as well.I suggest uninstall them too

Hi yes, i do have KIS installed, looks like there should be a fix soon. once its out, ill report back how i get on! Thanks! Ross.

Incidentally, you can do this workaround to get it up and running....... i tried and it worked, but ive now put it back and waiting for the patch http://support.kaspersky.com/kis2010/error?page=1&qid=208280937

Patch now completed by Kaspersky
