Opens Folder At Boot - Msconfig Stuck At Selective Startup

1. If I try to select normal startup in msconfig.exe, it doesn't stick; always reverts to selective startup.

2. When I boot to the Windows 10 desktop, it always opens a Windows Explorer window at /windows/system/ which shows only a Speech folder in the right panel.

3. Checking my BootManager using BCDEdit, I see this but I don't understand what the entries mean or whether any of them are connected to the problems 1 and/or 2:

Code:
