On Intel's own discussion forum are several threads on
the topic of solving the "outdated driver signature problem", specifically
on how to obtain and install the correct updated driver. This properly
solves the issue of device manager not installing the driver for the
Blaster, and Quartus not being able to see the Blaster. I too encountered
this issue when I first installed Quartus on Windows 10 about 6 months ago,
and though the process is a pain to follow it does solve both issues.

You first have to disable driver signature enforcement.
This is the sequence:
1 - Go to windows 10 settings and search for "advanced
startup options"
2 - Under Advanced startup, hit "Restart now"
3 - After a moment, you'll get a "choose an option"
screen - choose "Troubleshoot", then "Advanced options", then "Startup
Settings"
4 - You'll get a screen telling you what you will be
able to change and a single "Restart" button - press it.
5 - If your boot drive is BitLocker encrypted, you'll
need to enter the recovery key (press return, enter the key in the text box
then hit return again - it took me three goes to realize I had to hit return
before I could enter they key !)
6 - You'll be given a menu of options, number 7
disables driver signature enforcement
7 - When the PC restarts, use Device manager to update
the drivers - this time you'll get a warning about the signature, but they
install fine.
8 - When you've finished, restart normally to re-enable
signature enforcement
