Hi all, We have a Dell Inspiron laptop (running Vista) that will not install Windows Update KB3046017 (returns with error code: 80070057) and until this issue is resolved Windows Update remains on the taskbar and is constantly writing to the CBS log and using most all resources. This device is configured to have updates installed automatically. We noticed that when this condition surfaced Microsoft installed "Microsoft Office Powerpoint Viewer 2007". The device has Office 2007 installed, but only the Microsoft Word component. This update would not uninstall through the normal add/remove program procedure, but we successfully found and removed it in the Dell MediaDirect folder. This did not resolve this issue with KB3046017. I then ran sfc /scannow and the results, copied from the CBS log file indicate a problem that seems irrelevant: Cannot repair member file [1:24{12}]"settings.ini of Microsoft-Windows-Sidebar, etc. The sidebar has always been disabled and again, I think it may be a separate issue. Anyhow back to the Update issue. We think that the update may be intended for an Office product we do not have installed, but because this update is listed as critical we would like any feedback before we simply hide it.
