Windows 10: Winsat does not complete

I just installed Windows 10 x64 Enterprise, updated the drivers, and installed all Windows Updates. I then decided to run winsat but it doesn't complete. The error is:

Error in saving results to the datastore exe\main.cpp(5010)

I have 6 files in the C:\Windows\Performance\WinSAT\Datstore folder though: CPU, Disk, DWM, Graphichs3D, GraphicsMedia, and Mem. I'm missing the Formal Assessment.

Here's what I get towards the end of winsat.log:

For what its worth, I'm using EFI mode on my BIOS. I'm reading in the Internet that some people fix this problem by updating their BIOS but mine is already updated to the latest so I'm not sure if that's something. Please help. Thanks.

Cloned a HD to a SSD, then back to a SSHD, and now drive 'Optimization' only seeing a 'Solid state drive'

Winsat Formal fails saying the tool stopped working "A problem caused to program to stop working correctly.'

I've tried this many times before. :-/

In an elevated command prompt try running this command:

winsat formal -restart. This should cause Windows to reevaluate the disk drive. The command will take a little while to run, allow it to complete and then reboot.

 

Ok, I think I found out the bug. I switched back to Legacy Mode (non-EFI) just to test out the issue and surprisingly winsat.exe completed successfully! Why would EFI mode interfer with Windows 10 in any way then?
