I had some problems last weekend, installing the latest patches for Win XP SP2 (2 patches, KB951748 and the update for KB890830 - Malicious Software Removal Tool). I have AU configured to notify me of updates but I decide whether and when I download/install them. I picked 'download' for the both of them. Apparently the servers were quite busy because for KB951748 I saw an ' per update regulated ' code in my WindowsUpdate.log. However, the update for MSRT was downloaded - at least according to my EventLog, which also showed the message 'an Administrator has to be logged in in order to install this update'. This is normal, I assume this has to do with the settings of AU. Normally, a reboot would start the installation of the downloaded updates. This time the update for KB890830 wasn't installed. WindowsUpdate.log showed error code 0x80080008. Of course I have Googled this and I have found some solutions, but I was wondering if this would correct the update for KB890830 as well. It has been downloaded, but not installed. Will running Dial-a-Fix, re-registering dll's (and all other solutions offerd on the web) also make sure that this update for MSRT is installed correctly? If not, does anyone have any additional suggestions for how to take care of this?
