Windows Update fails to install with error code 8e5e03fb
15th July Windows Update suddenly stopped downloading and installing selected important files required to update Vista Home Premium SP1. The error code is consistently 8e5e03fb, not recognised by Microsoft even though I have seen posts on Forums dating
from April 2009 mentioning that code. I have been working with Alan Leon, Support Engineer, but without success. Some updates do get through but none are relevant to the OS or Internet Explorer. So far none of the articles in the Knowledge Base have been helpful. One
file, wucltui.dll, is missing from my system but Alan Leon did not confirm that it could be relevant. Alan has suggested that my problem could be connection related but his suggested changes to my settings did not bring the desired result. My ISP has a feature
that allows me to see data flow both up and down. When data is being sent or received it can be seen quite clearly but when Windows Update is running there is no data flow showing.

VI) Run SFC scan Please follow the steps as below to the System File Checker as the first steps:
1. Click Start and then type cmd in the Start Search box.
2. In the results area, right-click cmd.exe, and then click Run as administrator. You will be prompted to type the password for an administrator account. Click Continue if you are the administrator or type the administrator password. Then, click
3. At the command prompt, type Sfc /scannow, and then press ENTER.
Note: The scan may take some time, so be patient. Windows will repair any corrupted or missing files that it finds. If information from the installation CD is needed to repair the problem, you may be prompted to insert your Windows Vista CD.
Thanks and Regards,
