My XPS 13 9343 has Windows 10 1607 installed and runs very well.  I wanted to run Windows Defender's new Offline feature where you can start it from Settings - Updates and Security - Windows Defender - Windows Defender Offline.

When I click on the "Scan Offline" button, my PC seems to be doing what it should be, i.e., it shuts down and restarts.  However, instead of doing a scan, the Dell Backup and Recovery process opens instead.  Obviously, something is wrong here.

This PC originally came with Windows 8.1 installed (May 2015).  I performed the in-place Windows 10 update with no issues.  It currently has ALL Microsoft updates.

The only thing that I believe might be an issue is that, in addition to the C: partition and the EFI System Partition (500 MB), it has four(4) additional hidden partitions: OEM Partition (40 MB), Recovery Partition (750 MB), Recovery Partition (450 MB), and a Recovery Partition (6.5 GB).

Surely, some of these partitions are not needed, and I suspect may be playing a part in this problem. Any ideas?

Thanks
