please fix the windows 10 inaccessible device boot issue

Boot your system with a Windows PE or Linux Live CD and delete sptd.sys and/or sptd2.sys (whatever is there) in the Drivers folder, then try to boot normally.

No, that's not the problem or solution. The problem is not the existence or deletion of sptd.sys. It's the deletion of its registry information. If you delete the "HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/sptd" entry manually or by way of replacing the "start" value by 4 or using its removal tool which deletes the sys file and marks this entry for deletion. The sys file is there or not, keep this registry entry, you live; delete or have it deleted by any means, fresh windows installation or command line regedit.exe to create it from scratch. You are lucky for still keeping up your business after such a big screw up...very very sloppy job!

McKennaScole: Software conflicts happen... we did our best together with SPTD dev team to find and solve this.

We did just got a new SPTD version that should fix the problem:

http://alcohol-soft....mp/SPTD_212.zip

You will need to install this SPTD version (using the installer appropriate for your system, 32/64 bit), then restart Windows, and only then you can install the latest Alcohol version normally (Alcohol installer will detect new SPTD version on your system and will not install the included SPTD version)

Duplex Secure has released SPTD 2.12 which fixes the problem with NVMe SSD drives.
