After last “patch-tuesday” my Windows 8.1 don’t assign drive letters to hotswaped HDD’s and USB keys.
When starting my backup drive , it is now without a drive letter, I can give it one though in disk-management, but before last tuesday, it was given a letter automatic. Same problem when I connect an USB-HDD or an USB-stick.
If You too having the same issue, then here the solution
Done! Enjoy! Keep Visiting!!
