Access Send To menu in Windows [updated]
No, you don’t need to install any extra program, to edit contents of Send to...
context menu in Windows (source).
Instead, open any Explorer window and paste this as folder path:
%APPDATA%\Microsoft\Windows\SendTo
or hit Win+R, enter or paste shell:sendto
and hit Enter.
This was proven to work in Windows 7 and 8. Most likely this works in Windows XP, Vista and 2000 as well.
[update] This still works nine years after writing this article, in Windows 10 and 11.
