Windows Update startet nicht mehr etc.

Guten Tag,

ich habe folgendes Problem:

Neuerdings startet mein Windows Update nicht mehr, wenn ich dieses im Startmenü anklicke. Zudem öffnet sich auch Begrüßungscenter nicht mehr. Wenn ich in den Desktop rechts-klicke und auf "anpassen" gehe, um Bildschirmeinstellungen zu ändern, öffnet sich auch dieses Fenster nicht mehr.

Antivir zeigt mir keine Viren etc an. Ich habe auch schon gegoogelt, aber nichts passendes gefunden.

Mein Betriebssystem: Vista Business 64-bit.

Was kann ich tun?

Habe das SP deinstalliert und anschließend wieder neu installiert. Das hat nicht geholfen. Man sieht in Sekundenbruchteilen wie sich das Fenster öffnet und wieder verschwindet (bei Win-Update).

Ich versuche es mal mit Repair. Gibt es noch weitere Alternativen?

Vielleicht hilft das:
