Cherche déséspérement WMIPSESS.DLL (Vista x64 SP2)

Bonjour à tous

Alors voila suite à disque défectueux j'ai fait une sauvegarde (acronis) mais il y avais plusieurs clusters défectueux ...
Après restauration sur nouveau Hdd j'ai fait un sfc /scannow et j'ai un fichier corrompue qui n'a pu être réparé : WMIPSESS.DLL

Mon fichier C:\Windows\System32\wbem\WMIPSESS.DLL fait 59ko, d'après le rapport sfc ce serait la version 6.0.6001.18000 ...
Sur le net je n'ai trouvé que la version 6.0.6000.16386 de 44ko ...

Alors si quelqu'un a un Vista x64 SP2 ce serait super de le mettre en ligne !
