You may receive the error 0x80248014 when trying to manually update the antimalware definitions on a computer running Windows 8 with Forefront Endpoint Protection 2010 (FEP 2010) or System Center Endpoint Protection 2012 (SCEP 2012) installed.


Definition updates for FEP 2010 and SCEP 2012 can be distributed thru several sources. The problem occurs if Microsoft Update (MU) is the source used and the computer has not been configured to opt-in to Microsoft Update.


To resolve this issue, configure the client computer to opt-in to Microsoft Updates.

How to manually opt-in to Microsoft Update:
1. Open Control Panel
2. Click System and Security
3. Click Windows Update
4. Click Change Settings
5. Check the checkbox "Give me updates for other Microsoft products when I update Windows"
6. Click OK

How to programmatically opt-in to Microsoft Update:

Save the text below in a file with a VBS extension (e.g. optinMU.vbs):

Set ServiceManager = CreateObject("Microsoft.Update.ServiceManager")
ServiceManager.ClientApplicationID = "My App"
'add the Microsoft Update Service, GUID
Set NewUpdateService = ServiceManager.AddService2("7971f918-a847-4430-9279-4a52d1efe18d",7,"")

Run the below command in an elevated command prompt:

cscript optinMU.vbs
