Hello,This solve my problem:http://forums.techarena.in/windows-update/1130977.htm... The problem with KB963660 is most likely related to "Windows 7 GenuineActivation By Orbit30 2009 v2" or a similar patch that was released to makeW7 "genuine" before Microsoft released the public beta. Surely it was that patch that caused to my W7 the update failure with errorcode 80070643.I rolled back the patch, run slui.exe and retyped one of the product keythat Microsoft used to give out when W7 beta was available for download.Problem solved. Hope that you have a copy of the original files that were patched:%WinDir%\System32\spp\tokens\pkeyconfig\pkeyconfig .xrm-ms%WinDir%\ServiceProfiles\NetworkService\AppData\Ro aming\Microsoft\SoftwareProtectionPlatform\tokens. datJust copy the original files in place and run slui.exe. Since those files are part of a public release, I believe redistributingthem is not evil:http://drop.io/hidden/3fmrnwsputwbrd...5zLWRhdC1vcmlnhttp://drop.io/hidden/3fmrnwsputwbrd...0tbXMtb3JpZw==MFC
