Shadow Defender and Windows Defender on Windows 8.1

Hello,

I am using Windows 8.1 Pro Update 1, 32bit.

I have also Shadow Defender installed, with "Enter Shadow Mode on boot"

Now, what folders do I need to exclude on Shadow Defender so I can update Windows Defender on Shadow Mode? I have excluded the C:\Program Files\Windows Defender but still when I update on Shadow Mode and exit on Shadow Mode, the update is lost (in Normal Mode).

What registry/folders do I need to also exclude?

Please help. Thanks.
