A check for updates will result on the message: However, ZDNet has reported a different error: But no matter which error you get, they will result in the same problem. According to Computerworld, the root of the problem appears to be that Microsoft neglected to change the expiration date of a file, which might just be the reason that users are seeing this error in Windows Update. If you see this error, a suggested temporary solution is to set the system date to anything older of 12/03/2017. Alternatively, it also appears that disabling “Give me updates for Microsoft products and check for new optional Microsoft software when I update Windows” in the updates settings is fixing the error 80248015 for some users. It’s not just Windows 7, it also seems that devices running Windows Server 2008 are reporting the same error 80248015 trying to update. Update December 5, 2017: A spokesperson from Microsoft said to ZDNet that the company has fixed this issue for devices running Windows 7 and Windows Server 2008.
