Disown process from cygwin bash

There is a way to properly disown process from cygwin bash?

for example i can run in background

/cygdrive/c/Windows/notepad.exe &

and the notepad window shows but when i close the bash using Ctrl+D or typing exit the bash window remain open

Solution 1:

cygstart notepad

Or, if you're using mintty:

setsid notepad

(setsid is in the util-linux package.)
