Error Code 80248015

I did just find a work around by unchecking  all the settings and going to never have updates.  Then I was able to get updates again when reset to manual, and found two huge security updates.  Maybe they are inundated as the updates were huge.  I was able to update with them and now it works again.  But unchecking everything seemed to clear it out as automatic update did not work.  Manual seemed to work.  I hope it stays fixed now.

Non working WU, why not.

I remember WU said I needed an update for a laptop I had. Surprise, surprise I installed a recommended up for a touch screen and I didn't have one. That was a treat>>>

Actually Window Update doesn't need Silverlight to run.  However, Silverlight needs to have Windows Update set to update other Microsoft products in order to be updated itself, so as part of it's installation it enables update for other Microsoft products in Windows Update.  You don't need to keep Silverlight if you don't want it.  Uninstalling Silverlight will not stop Windows Update from updating other Microsoft products.  Installing Silverlight is just a quick way to get Windows Update back to full operation.  I uninstalled Silverlight and WU still works just fine.

Quick update after restoring Win Update functions ALL previous histories --including the 'Hidden updates' were restored.

Microsoft has released a fix. For those who has still issues with Windows Update, because the fix isn't installed automatically, see my blog post for further assistence. Hope it helps:
