NSA325 with Windows 10

My NSA325 has become hard to manage because attempts to connect over HTTPS often fail.  This started because I was finding that the NAS had become invisible on the network so I couldn't even browse it in the File Explorer.   A restart usually makes it visible again, although at the time of writing, having just done a hard reboot, I still can't connect (attempt to open http://192.168.0.230/r49603,/adv,/loginwrap.html returns Error 404, although my initial call was just to the IP address without the parameters, so something must be picking up the call and making the subsequent call to the login dialog).

Also, the NAS Starter Utility installs but does not run correctly on Windows 10.  

 I therefore have two questions:

1.  Is the NSA325 in some way incompatible with Windows 10?  It clearly works up to a point, but is there something fundamental about the file system that makes it work only partially?

2.  Is there a version of installable software for Windows 10 that reliably enables a connection to the NAS for the purpose of administration?
