FileMenu Tools (freeware)
is probably your best option if you can't get MMM to play nicely.
You won't be able to re-order items for third party and/or Windows entries, though you can remove most unwanted items.
The program adds a single context entry of it's own via which you can customise a range of additional functions and built-in utilities, which can be re-ordered to your liking. You can manage the SendTo menu, and add your own sub-menus and custom commands.
Some of the things I like include;
Built-in file shredder with x1, x3, x10, x35 options
Change file and folder attributes faster (such as view hidden items)
Run a program with attributes
Once installed go to Programs > Lopesoft > Configure FileMenu Tools
