Started to have problems with Windows update this year. Clients got info about updates and notification popped up saying that updates are available. But if I tried to install the it said that download failed. From event log I saw messages like:
The contents for update b1dd2c2c-cab1-4f19-ab7b-2f1145dc3549 could not be located.

Somehow it shows two updates with same title. b1dd2c2c-cab1-4f19-ab7b-2f1145dc3549 existed actually but I didn't see any update with id 731c2778-3493-40b6-92ec-6c784e1c6af6. Not even from expired updates.
I had the problem on the January and February but somehow it disappeared after day or so. No problems on March but now on th April I can't again install updates. Can't figure it out and trying to just wait it out right now. Maybe it resolves itself again after day or couple... but if anyone has some ideas about solving it then they are welcome.
