Any hope for error update error code 80070490

Since purchase of this computer Windows has never been able to check for
updates, it gives "unknown error code" 80070490.

All of my other products can update, is there any hope for me?

Operating System?
Service Pack level?
Was this a *used* computer?

How To Ask Questions The Smart Way
http://www.catb.org/~esr/faqs/smart-questions.html

• Which version of the Windows operating system am I running?
http://windows.microsoft.com/en-us/w...m-am-i-running

• Is my PC running the 32-bit or 64-bit version of Windows?
http://windows.microsoft.com/en-us/w...t-32-or-64-bit

Always state your full Windows version (e.g., WinXP SP3; WinXP 64-bit SP2;
Vista SP1; Vista 64-bit SP2; Win7; Win7 64-bit) when posting in a forum or
newsgroup. Please do so in your next reply.

What anti-virus application or security suite is installed and is your
subscription current? What anti-spyware applications (other than Defender)?
What third-party firewall (if any)?

Has a(another) Norton or McAfee application ever been installed on the
computer (e.g., a free-trial version that came preinstalled when you bought
it)?

For the many affected that are scouring the Net for a solution to this
problem there is hope! After much digging I found the "System Update
Readiness Tool for Windows" (REF:
http://support.microsoft.com/kb/947821/en-us).

After installing this tool / update on a Vista SP1 x86 installation I was
able to download the > 90 updates available. Please note that the fix took
some time to complete and I rebooted the affected machine before downloading
and installing the delta updates.


Hope this is helpful!
