Windows Update Error 80070490

Here we go....


I've uploaded a file - lryad.zip - to my OneDrive at Noel's OneDrive
Please download and save it.

Right-click on the saved file and select Extract all...
Change the target to C:\ and click on Extract
Close all windows (it would be a good idea to print these instructions!)

Now reboot to the Repair Environment - as soon as the machine restarts, start tapping F8 - this should bring up the Advanced Boot Menu, at the top of which should be the option 'Repair my Computer'
Pick that
You'll have to log in with your username and password.

Pick the option to use a Command Prompt
At the prompt type
DIR C:\lryad
hit the enter key - if you get a 'Not Found' error try
DIR D:\lryad
or
DIR E:\lryad



The drive letter in use when you find the folder will need to be substituted (for<drive>) into the following command...



XCOPY <drive>:\lryad <drive>:\windows\winsxs /y /i /s /v /h



(e.g. XCOPY P:\wfire P:\windows\winsxs /y /i /s /v /h )



run the command (it should take almost no time) and when the prompt returns, type
EXIT
and hit the Enter key to exit Command Prompt - reboot to Normal Mode Windows.

Now run SFC /SCANNOW in an Elevated Command Prompt
then reboot and upload the new CBS.log file to your reply

The file should be up there - it shows for me?

The boot options menu sounds as if something changed in the BIOS settings - probably nothing to worry about.

You need to make sure you get the spacing right..


XCOPY<space>C:\lryad<space>C:\windows\winsxs<space>/y<space>/i<space>/s<space>/v<space>/h

Don't worry - it may not be your fault...

Back in normal Windows...
Open an Elevated Command Prompt and run the following commands...

ICACLS C:\Windows\winsxs
ATTRIB C:\Windows\winsxs

post the results...


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.
