Error Code 80248015

Firstly, make sure the link opens in Internet Explorer - might be easiest to make it your default browser just for this operation.

Then it should ask if you want to install the Microsoft Update activex control or something similar, cant recall the exact message.

This should take you to the page, in IE, which lets you subscribe to microsoft update once again.

You may need to add the *.microsoft.com domain to the 'Compatibility View' options in IE - no idea why but for some reason their own page needs that to render properly.

authcab.cab is expired - on december 3rd. We need a new authcab.cab from microsoft. this effects all versions of windows up to windows 7 (including windows xp embedded)

Ha. I had the exact same reaction to those Windows Update errors as you and my MSE is now also borked (80242014). After reinstalling the MSE the first update went through without a problem and now I am getting error messages (80242014) - same as you.

I don't think we did something "wrong". There is something wrong with die MS servers right now.

I knew MS was going to end support for windows 7 at some point, but I can't believe they didn't even have the courtesy or moxie you let people know if that is indeed what is going on.  We're left here not knowing if it's a royal MS screw-up, or if they have just dropped us windows 7 users like yesterdays bath water.  Whatever it is, I'm PO'd big time.  Whatever it is, it's MS's fault/problem.

Authcab.cab's .XML has these entries

<ServiceID>7971f918-a847-4430-9279-4a52d1efe18d</ServiceID>

  <CabVersion>8110</CabVersion>

This is a MS issue so they will need to update the cab.

I also have the same problem.Cannot load updates.Everything working fine  until this.error 80248015.Last update worked fine so it happened then.

Likewise.  I suspect it has something to do with no longer giving windows 7 users the option to choose which updates they want to download, like it is with windows 10.  As you probably already know, with windows 10, microsoft stopped giving any options as to what or when updates were downloaded.  Either that, or some really unqualified geek at microsoft did something terribly wrong.  Let's hope we all get an answer on this.  It's all about control and no choices IMO.
