sowas findet man übriegens zu dem Thema auf den Hilfeseiten von MS:
Hi,
This ought to help you out, just follow the instructions herein below:-
Stop the notification of KB2478658
=======
1. Please first go to the following link:
(Du musst Dich Einloggen oder Registrieren um Multimediadateien oder Links zu sehen). 2. After the scanning process, please check if we receive a page with two buttons: Express and Custom
If yes, please click Custom.
3. Then please clear the check boxes in front of KB2478658. Meanwhile, please check the check box in front of "Don't notify me about these updates again."
4. Quit the Windows Update window.
Note: It may indicate that you have hidden important update. It is normal, please ignore it.
After that, the update KB2478658 will not prompt to install again. It won’t affect other updates. The security level and the system performance won’t be affected either.
Please restart your computer and check if the issue is resolved now.
Tja dann werd ich wohl erstmal überall die Updates installieren und diese dann im WSUS ablehnen.
Was mich halt wundert, ist dass scheinbar sonst niemand dieses Problem hat...
