Hi

Is it possible /supported to scan windows installation via WinPE?
I was testing the procedure outlined here for USB creation here:

After some adjustments was able to integrate to WinPE image ... however, it wasn't successful as Defender defination was outdated and I must have internet connection to perform a scan.
Can we configure /customize somehow to run scan without internet? Maybe not check for the latest defination update but rely on what is available in PE local assets?
Or any other optimized method?

    Hi,

    It is supported to scan windows installation via WinPE.

    And we strongly recommend that you update latest full definition files. You can visit Launching a Windows Defender Offline Scan with Configuration Manager 2012 OSD and follow steps in Building the Windows Defender Offline WIM to perform scan via WinPE.

    Hi,

    Was using the same link Config Mgr 2012 OSD but it always show error as definitions are not upto date.
    Where I should place the definitions files precisely?
    And limit to the local repository only thus without Internet connection?
