iTunes library still intact, everything else still seems okay. Jus updated again, everything including iTunes still okay.

It's going to have to wait a week as I'm going away before I can do that download
Finally worked out what was going on. The computer had originally been Windows Vista with the usual local account as Administrator that I upgraded to Windows 8.1 and then further upgraded to Windows 10, tacking a Windows Live account on (as Windows kinda insists) along the way.
The latest (automatically installed) upgrade, where I thought I had lost all my settings, Dropbox etc. was because the logon had reverted to the local account not the Windows Live account. Once I worked that out and logged in using Windows Live everything was where I expected it to be. I've since deleted the local account
