Hello, Unable to run windows updater. IF I MANUALLY prompt for updates, it fails ["Windows could not search for new updates']and gives the following error code 80070005. If the system automatically searches for updates, it will succeed in locating with the prompt to download and install. I then attempt to install (and it shows all updates successfully downloaded and installed), but upon restart, it fails and "reverts" back to all settings prior to the updates. The updates themselves will have the error code; 80071a90. I had one of the security trojans prior to this event and possibly during removal from the system, it corrupted one of the registry files? (Since removal of the trojan, this appears to be the only issue...) Note; ".NET framework 4" AND "Malicious software removal tool" updates WILL successfully install through the updater, but they are the only updates that are successful. I have attempted installing WIN 7 CD and repairing,... run sfc /scannow,... update troubleshooter, fix it tool, accesschk, subinacl, etc. Unable to find any 'similar' problems in any forums.Any help would be appreciated...thanks..scott

The error 80070005 indicates you do not have enough permission to install the update.

Hi Luigi, Thank you for your response, but I have already attempted that fix with no success (although I already had admin permissions). Thanks agains...scottscott

download latest version of windows update agent http://support.microsoft.com/kb/949104 stop windows update service delete C:\Windows\SoftwareDistribution folder start windows update service install the new version that you have downloaded force updates scan wuauclt /detectnow My guess is that one of the updates left your computer in reboot pending state which only allows now updates to be installed if they do not need reboot.

Hi Brano, Thank you for the response...I attempted your repair suggestion and thought it may work ...and it was 'partially' successful. I say partially, since now I can "manually" search for updates and it locates them without failing. I no longer get the 80070005 code. The remainder of the problem is still there...only .net framework and malicious software removal tool updates are successful. The rest fail and the code on the failures (all) are; 80071a90. Previously, I had attempted a repair by stopping the update service and writing over the existing script in an attempt to fix (but no success). Your method has at least cured part of the issue. Thanks again..scott scott

Hi, Please refer to the following article to see if it helps in your rest of failure: Windows Update error 80071A90Alex Zhao TechNet Community Support
