There's no errors in your posted logs.
The 80070002 error is a 'file not found' one - please post your C:\Windows\windowsupdate.log file and I'll see if it gives me any clues.

Hmmm - let's try a different approach, then...

Open Event Viewer
click on the Windows logs entry in the left pane to expand it.
Now click on the Application entry - wait while it loads.
Click on 'File' in the menu bar and select Save...
Save the file as Appevt.evtx
Repeat for the System log
then zip both, and upload them.

The system is having problems opening the HOSTS file, which regulates some of the access to networks.

Please open an Elevated Command Prompt and run the following commands...

ATTRIB -R -N -S -H
REN C:\Windows\System32\drivers\etc\hosts hosts.old
Echo "# Temporary Hosts File - NDP" >>C:\Windows\System32\drivers\etc\hosts

close the window and reboot - see what happens.

Here are some instructions to make life easier :)
1) To open an Elevated Command Prompt Window (the ECP window), click on Start, All Programs, Accessories – then right-click on Command Prompt, and select Run as Administrator. Accept the UAC prompt.
2) To run the commands easier, highlight the block of commands, and right-click on the highlight – select Copy. In the CP Window, click on the black/white icon at top left – select Paste. The commands will run but may not complete the last command, so hit the Enter Key once.
3) To copy the results... click on the Black/White icon in the top left, and select Edit... 'Select All', and hit the Enter key - then use Ctrl+V or r-click+Paste to paste it into your response.
