You need to have patience when you are running something like that - I'd try it again.
It had obviously made some progress for you to get a different screen.
I'm running it again on another machine to refresh my memory.
Did you select My Update Center and Ethernet connect for it to update its Database before the scan ?
I momentarily had a couple of lines where it said it had failed something or other but it wasn't on the screen long enough for me to read it.
Not sure if Ethernet connecting resolved that.
While I've never read the manual, in the Objects Scan menu I don't have C: listed.
This is on a Win 10 machine.
The default two are for Disk Boot Sectors and Hidden startup objects.
It gives me three others as sda1, sda2 and sda3 but when I've run the scan previously to get me out of the mire, I've just run it on the default settings selected.
The sda files have icons on the desktop which when clicked on, do cover other items such as AMD for that machine, so it may be prudent to check those boxes as well, given that you are getting a BSOD.
When it has updated its database - and it's still on 41% and has been updating for about 30mins now, I'll select all of the items and see how it progresses and let you know later.
I wasn't prompted for a username or password - but the machine isn't password protected.
For you, that may have been because you had selected C: which I can't replicate.
Don't throw it out of the window yet
