Ps. Smb1 in Win10 ! I mean ofcourse.. 

Step 1: Go to Start button and type Control Panel. You will get Control Panel; Desktop app. Click on it.
Step 2: You will get a window with a list of software on it, go to the left side of the panel and click Turn Windows Features On or Off.
Step 3:  You need to remove the checkmark beside SMB 1.0/CFs File Sharing Support to disable SMB1 for good. If you want to enable it, put a checkmark beside the same.

And after seeing this, 
@Rowland, can you do a read in this one. 

Your english is better then mine, but i do think this is related. 
Could bug#13698 (marked fixed today) also have influence here. 

And might be related: 
Cant think of much more.
