Dear Friends, For about the past month my Windows Updates Vista downloads, will not install - they download, create a restore point & look as though they are about to complete the installation process, following which I receive a message "Failed" . I have on my machine a long list of Failed Downloads. I have tried a Microsoft "Fix it" which did not work. I've also tried temporarily disabling my AVG 2012, still no luck with the download installation. I've cleared my browsing history in IE 9 to see if that might help, all to no avail. The error code I am receiving is: 8E5E03FA - Windows Update encountered an unknown error. I'm running Windows Vista Service Pack 2 & IE 9. Any help / guidance which may resolve this problem would be greatly appreciated. With thanks and kind regards, Betty Sharp
