Hi,
to see the cause of Windows 8 update failures, we must look for error messages in the following log files:
Please run the Windows Explorer and go to the folder "C:\Windows\Logs\CBS\" and copy all files to your document folder, also copy the setupapi.dev.log from the folder C:\Windows\Inf, the "C:\Windows\WindowsUpdate.log" and the file "C:\Windows\winsxs\poqexec.log"
to your document folder (otherwise you can't upload it), zip all files into 1 ZIP and upload the zip to your SkyDrive [1] and post a link here.
