After trying a number of the suggested fixes when Vista failed to install
updates and gave me error message 80073712 I came up with a procedure,
modified from other's suggestions, that worked.
1. Go to
http://www.gibinsoft.net/ and download the GIPO@Utilities Files
2. Run GiPo@moveonboot and tell it to rename c:\windows\winsxs\pending.xml
to c:\windows\winsxs\pending.bak
3. Follow instructions to Reboot the System. When you do you will get a
message on reboot that some system component or functions may not have
connected or a similar message . Just ignore those messages and go to
Internet Explorer and type in
http://download.windowsupdate.com/v7...agent30-86.exe
and when prompted, tell it to run the file. This will manually install
windows update agent. Answer yes when prompted if you want to install this
and ultimately it will tell you to reboot once more.
4. When you reboot it will probably say it is reconfiguring updates. When
done go to IE Tools and click on update and it should install all of the back
updates. Then reboot once more - hold your breath while it goes through the
familiar Reconfiguring Updates Message and eventuallythey will all be
installed (I had 20) and the problem will be solved!
Hope this works on your computer. Best of Luck.
