If you're getting error 80248015 when updating Windows 7, and if you're seeing:

"A check for updates returns the error message "Windows Update cannot currently check for updates, because the service is not running. You may need to restart your computer".  The error 80248015 is displayed, but anything you try to resolve the issue on your end fails...Woody on Computerworld suggests that Microsoft broke updating on Windows 7. He suggests, based on a user report on his Ask Woody website, that Microsoft may have missed updating the Expiry Date of a file, and that this may be the cause for the update issues." - gHacks

A possible solution is offered by:

"Günter Born discovered that disabling "Give me updates for Microsoft products and check for new optional Microsoft software when I update Windows" in the update settings fixed the issue on his end. You may want to try this to see if it resolves the issue for you as well." - ibid

Not so great that MS left off an expiry date when updating files, but it has happened before (3 yrs. ago).

Anyway, just some help if this is happening to you...
