problem solved with Version 10.0.0.6092
I have an unformatted external USB3 drive present when booting up Windows 10 64bit.
It is used with encryption Software, so no Windows-known format on device.
After USB initialization Windows booting stops - the animated circle goes round and round but nothing happens, no finally bootup for 30 minutes.
If I boot without that unformatted device, everything is fine.
There was no problem with Version 8.4, so I think, something’s changed in the way CIS 10 is recognizing devices.
Please help me with this problem.
