The AppDatafolder in the below step is a hidden folder, try the below step to unhide it and later try the steps mentioned.
a) Open a Windows Explorer window.
b) Click on the Organize button
c) Click on Folder and Search Options.
d) Select the radio button “Show hidden files, folders and drives”
e) Uncheck Hide protected operating system files (Recommended) box.
f) Uncheck Hide extensions for known file types.
g) Click Apply and OK
Try the below step to delete the sticky note.
a) Navigate to the following location.
b) Click on Start and type C:\Users<UserName>\AppData\Roaming\Microsoft\Sticky Notes
c) In the Stick notes folder you will find a file called StickyNotes.snt
d) You will need the file named StickyNotes.snt
Note: If you delete StickyNotes.sntfile this will delete all the sticky notes present on the computer event the new ones.
Make sure that you backup any newly created sticky notes.
Hope this helps!
