Another Windows update KB3000850 fails with error 800700a1

[msmsms]

I've tried sfcfix, scan sfc, turning off windows defender, windows update troubleshooter, adding the system tools folder, using the stand alone installer, dism...scanhealth, dism...restorehealth...nothing has worked. Gets to 99% complete and then undoes changes.

Any help would be appreciated.

On a Dell Venue Pro 11 if that matters...

SFC /SCANNOW

1. Right click on the
   
   button
2. Click on Command prompt (Admin) => Press Yes on the prompt

Convert CBS.log to CBS.txt

1. Right click on the

It will take about 15 minutes to process. Once the scan has completed a notepad file will launch with the results. Please copy and paste the entire contents of the results and post them back into this thread. Please put [CODE][/CODE] tags around the log to break up the text.

This is rather interesting, this is the first time I have seen this error without a certain file being corrupt!

Software Distribution rename

• Click Start -> Type in CMD in the search -> Right click on cmd.exe and choose Run as Administrator
• Entre in the following commands:
  net stop wuauserv
  ren %SystemRoot%\SoftwareDistribution\Download DL.bak
  ren %SystemRoot%\SoftwareDistribution\DataStore DS.bak
  net start wuauserv

Once completed please try and run windows update again.

if WU still fails please run SFC /SCANNOW and upload a new log.
