Silverlight missing from WSUS

As you might have noticed there's currently no update for Silverlight available for WSUS or Configmgr. Took me a while to figure it out ,so i thought I'd write a short post about it to save others some time.

You might have noticed that your clients is prompting you to update silverlight ,but when you check WSUS or SUP you can't find any silverlight updates.
The reason for this is that in the Desember 2014 updates(KB3011970) there was update containing Silverlight (v5.1.31211.0) ,but this patch got revoked pretty quick because of some Active X issues.
When they released this they expired KB2977218 from July containing Silverlight v5.1.30514 so now there is currently no update for Silverlight available WSUS / Configmg.

So to summerize:
KB2977218  released in July 2014 containing Silverlight 5.1.30514 is now expired.
KB3011970  released in December 2014 containing Silverlight 5.1.31211 was revoked

So if your clients is running an older version of silverlight your users will be prompted to upgrade silverlight when they visit a silverlight page.
5.1.30514 is listed as the latest release on Microsoft ,but the update containing this version is expired so you can't deploy as you normally would ,trough WSUS.

For now you just have to live with the "Silverlight is requesting an Update" messages or  to deploy it manually.
