 ... but no Notepad appearing I presume. So this does sound like Denemo
is failing to launch anything. I've noticed that Windows batch files
get an extra parameter, so the RunNotepad should reference %9 not %8 -
using %9 Notepad succeeds in opening the output lilypond file. When
running a version which fails does Denemo actually generate a (new)
file 

C:\Users\joean\AppData\Local\Temp\Denemo_XXXXXX\denemoprintB.ly

to check, use the cmd.com or tell the file manager to show "hidden
files" as AppData is hidden by windows by default.

You are the only reporting it - I know of two Windows 10 machines that
are ok with the overnight build.
