Havde samme problem, det her virkede for mig, og jeg kan igen installere alle updates.

CAUSE
This issue may occur if the catalog database (Edb.log) is damaged. The catalog database is referenced by Windows Update and Windows Media Player. If the catalog database is damaged, the update may not install correctly, and you may experience the behavior described in the "Symptoms" section of this article.
WORKAROUND
To work around this issue, follow these steps:
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.

takker, det var næsten for let:)

Kig lige på mit link igen, ellers er problemet der jo bare igen næste gang du skal opdatere.
