Silverlight Security Update problem.
KB2668562 - Microsoft Silverlight Failed to update. - Microsoft Answers
Thanks to responses on this listserver, we've looked into the Silverlight update, have identified a metadata (logic) error and will be releasing a revision to correct this very soon.
Consider holding off on this update until a revision is published and visible in your WSUS/SCCM consoles - or simply allow auto-approval to permit the revision to replace the original version. We have similarly 'down throttled' unmanaged (consumer) machines until the revision is released (throttled at 0% = no consumer machines will get this installed automatically - but users who open WUApp and choose it, will still be able to run it - even though it will fail).
