Windows 7: windows experiene index fails on win 7

I just installed win 7 home premium 64 bit? I had win 7 ultimate 64 bit rc on the same machine prior to the home premium install and everything worked fine, including the win experience index with high scores on all but drives At 6.2
the message said that "the windows experience index for your system could not be computed and adding that this is due to an error being reported via the OS, driver or other component
Every thing worked perfectly with Windows 7 ultimate RC 64 bit and I have been using it since technet released it
Thanks Joe

i had the same problem. in fact, i just posted about this issue (not solution yet) a thread or two below yours.

i found this...

The windows experience index for your system could not be computed

a disk check worked for that guy.

FWIW, I gave the above a try and it didn't work for me.

I tried disk check, no good..I'm pretty angry at myself now for buying it, I paid 200 bucks and took a step backwards

Hi All, Just to say I'm getting the same problem on my Windows 7 64bit install, everything worked ok onmy previous Windows 64bit RC.

Hi all I'm getting the same problem on my windows 7 x64 version.

I have found the problem on my system, the problem was caused by Kaspersky Internet Security 2010, the very latest update release, hope this will help anyone else out with the same problems, please repost if it fixes your problems.

How did you fix did you remove Kaspersky 2010?

I just paused protection and also exited kaspersky 2010 and the wei still fails I am loathed to remove it for ovious reasons. But I will try that now and report back

thanks Sybex,

yes, i can confirm this.

i've been running various flavours of 7 for several months with kis 2010 9.0.0.463, with zero problems with wei.

however, my new install, with kis 9.0.0.736, has made it impossible for me to measure my wei.

so i tried uninstalling, and guess what, i got a wei result. simply pausing protection or exiting the program was not enough - a full uninstall was needed.

i hope kaspersky fix this soon, in the meantime i've gone back to kis v463.

i'll do some research on the kaspersky forums and report back if i learn anything useful.

wei is pretty useless anyway, and everything else seems to work ok, but it's still a bit bothersome...
