For Windows Version 1709, OS Build 16299
If SANmp is already installed when running this Windows update, it will not launch correctly afterwards, and will require uninstall/reinstall. You'll find the current SANmp version here.
In this Windows version, it is possible to mount volumes if allowing a drive letter to be automatically assigned. Windows will crash and restart if an attempt is made to manually assign a drive letter when mounting, mount to a directory, or if the permission mode is changed without first unmounting the volume.
Once a volume is mounted, changing the mount type (R/W, R/O, etc.) will require first unmounting the volume.
