If Updates fail to install:-
If you receive a 643 error message or a message indicating
that Windows Update was unable to complete the operation.
This may occur if the catalog database (Edb.log) is
damaged.
Try this:-
Click Start, click Run, type cmd, and then click OK.
At the command prompt, type the following command, and
then press ENTER:
del /q "%SystemRoot%\System32\Catroot2\Edb.log
This command will force the catalog database to rebuild
itself.

If the Windows Update scan feature reaches 100%, and then
displays "There are no updates available at this time"
message.
Verify that your computer's date and time are accurate and
that the Internet Explorer language option is not empty.
To check the language setting in Internet Explorer:
1. Click "Tools" and then choose "Internet Options"
2. Click the "Languages" button
3. Make sure at least one language is listed in
the "Language Options" dialog.

Windows Update Is Not Installed

This issue may occur if you use the AOL Web browser
interface to access and download Windows Updates. The AOL
Web browser does not communicate properly with the Windows
Installer software, and this may cause Windows Installer
to stop responding.
You can download them from the Catalog and save to be
installed later.
