Very Slow Startup on Windows 10 (SSD)

Hi,
Winscp 5.9.4 (Build 7333)
Windows 10 1607 (Build 14393.693)running from SSD
The start-up of Winscp takes ~10 seconds, even a immediate restart.
On the same Computer (Dual-Boot), but Windows 7 from HDD, Winscp starts almost immediately.
If you need any more informations, log-files etc., just notice me.
Thanks

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

Seems, I've found the cause after examining the trace.log.
Winscp (IEDriveInfo Component) tries to detect/access the non-existing A: drive.
After disabling the floppy drive in the PC BIOS, Winscp starts immediately.
I remember, floppy was disabled before, but for some reasons, the BIOS was reset to defaults 1-2 weeks ago...

Thanks for sharing your solution.
