How do I recover a closed Sticky Note in Windows?

"There will still be something of a ghost remaining in the file where Sticky Notes save the notes to. This can be found in

%AppData%\Microsoft\Sticky Notes\StickyNotes.snt

I was able to recover a deleted note from there simply by searching for a part of its contents and the plain text is usually pretty good copyable from there, unless you have some heavy formatting in the middle of it—then you have to deal with RTF. :-)"

"you can restore it to the previous version available
open the the file
%AppData%\Microsoft\Sticky Notes\StickyNotes.snt

right click on the file stickyNotes.snt and restore it to the previous version available"
