A new error message is currently plaguing Windows 7 users. Whenever the users are trying to search for new Windows Updates, the system is throwing up a 0x80248015 error. A quick look at the Microsoft forum reveals that this problem is pretty common to the Windows 7 users. The problem is likely to be caused by an update file that is mistakenly set to expire on December 3rd, 2017. Since the file has already expired the update process fails and thus eventually ends up showing the 80248015 error message.

Users of Microsoft Forums reported that a certain fix by Born City fixes the 80248015 error issue on Windows 7. This step involves unchecking the option titled “Give me updates for Microsoft products and check for new optional Microsoft software when I update Windows.” This setting can be found by heading over to Control Panel > System and Security > Windows Update > Change settings.
