I do have it, but it's not the same as yours you have 3 or 4 more entries and a much shorter list
Truthfully, there is nothing I can do about 3rd party extensions, they need to be built into Windows or entries such as Video LAN player, open in WMP, unlocker. it all depends what type of file you're trying to open.
To undo this mess, see if you have a restore point to go back to
