Once WinPE is booted OfflineScannerShell.exe is launched. The Winpeshl.ini which is used by winpeshl.exe contains the following command:ĪppPath = "%ProgramFiles%\Microsoft Security Client\OfflineScannerShell.exe" The startnet.cmd only contains the wpeinit command which instructs WindowsPE to install Plug and Play devices and load network resources. You can either mount the boot.wim using imagex.exe or use 7-Zip as explained here. The Windows Defender Offline Beta media is now complete, let’s take a closer look at the content within the boot.wim file that is stored within the Sources folder. Unfortunately the Windows Defender Offline Beta media preparation wizard does not have an option to add network or storage drivers, but I will show you within one of my next blog posts how you can customize your WDO boot media. Once the files are downloaded the wizard launches the imagepackage32.exe / imagepackage64.exe that contain the WindowsPE source for the corresponding architecture and finally mpam-fe.exe or mpam-fe圆4.exe is copied to the root of the media. Next for the 32-Bit version the file imagepackage32.exe is downloaded from or imagepackage64.exe for the 64-bit version from When using the 32-bit version it downloads the file mpam-fe.exe from, when using the 64-bit version it downloads the file mpam-fe圆4.exe from.

If you selected USB you will be prompted to select the USB drive, if you selected ISO file, you’ll be prompted to specify the location where the ISO file will be stored. Now let us launch the wizard and see what happens here. Now whether you download he 32 or 64 bit version, the content of both files is nearly the same except for the file called mssstool.ini When you launch the downloaded executable mssstool32.exe or mssstool64.exe which are self-extracting archives the content is stored in a temporary folder in the root of your system. First when you go to the download page you will see two download buttons, one for the 32-bit version and one for the 64-bit version.īy clicking on one of these buttons, you will not download the tool itself but just the Wizard that helps you preparing the USB or CD/DVD media. Now when looking at the log files produced by the Windows Defender Offline tool, you’ll notice Microsoft Standalone System Sweeper tool entries rather than Windows Defender Offline.īut let me start now sharing my findings about how the Windows Defender Offline Tool works.

While Security Essentials and Safety Scanner run within Windows, the purpose of the Windows Defender Offline Tool is to run offline from bootable USB or CD/DVD media. You can also use this tool on Windows 11.In addition to the Microsoft Security Essentials software and the Microsoft Safety Scanner Microsoft just recently released another FREE antimalware removal product called the Windows Defender Offline Beta. We are focusing this guide on Windows 10, but the anti-malware tool is also compatible with previous versions, including Windows 8.1 and 7. Also, the Safety Scanner expires after 10 days after being downloaded. When using this tool, it's always commended to download a new instance for every scan. You can always see the complete list of options using the msert /? command. If you use the /q option, the tool will run in the background without a user interface.
