Failed Windows Update, error 80070490 re kb2904266

With my abysmally low upload speeds, this could take an hour or two to appear, so if you don't see the file initially, go back for it every 15 minutes or so (it's 93MB!)


I've uploaded a file - jhgab.zip - to my SkyDrive at Noel's SkyDrive
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:\jhgab
hit the enter key - if you get a 'Not Found' error try
DIR D:\jhgab
or
DIR E:\jhgab

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

XCOPY <drive>:\jhgab <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 SkyDrive Public folder, and post a new link

None of the tools from the companies I mentioned are worth the download costs, let alone the license cost.
There is no such thing as a 'good' registry cleaner/optimizer - only ones which are marginally less bad. None should be used unless you have enough knowledge of the registry not to need them.

A decent tool - so long as you steer clear of the registry cleaner function - is CCLeaner (www.piriform.com)

Go for it!

490 errors can be a pain - try installing it from the download here....

This would appear to mean that the SoftwareDistribution folder is corrupted (I think)


This could be due to corruption in the SoftwareDistribution folder - the problem with that the conventional cure can lead to problems later on, if not handled properly, and you will lose your Update history (but the updates will still be installed, and viewable in the Installed Updates listing).

Open an Elevated Command Prompt
Run the following commands

NET STOP WUAUSERV
REN C:\WINDOWS\SoftwareDistribution SDOLD
NET START WUAUSERV

wait 15 minutes, and reboot
then wait 10 minutes, and open Windows Updates, and run a Check for Updates.

Install only the oldest update found - and reboot once installed
then go back to Windows updates and install the others.
