Please help me repair my right click menu on Windows XP

Ok so i just did a nice clean reformat and it looks like i did to much installs and treaking at once because now my right click menu is missing entries. When I right click a file, any file, txt, jpg, mp3, etc there is no “Open” there is an “Open With” option which slides out so i can open the files but no open. There used to be. I have an XP Virutal Machine and just confirmed the same files have a right click open there. Here is a screen shot:

Is there some kind of software that will repair this for me? it has to be some kind of reg tweak. Even better would be a software that lets me edit them completely to get rid of all that PDF and AutoCAD crap

bump…

I’m guessing there is no ‘Open’ because there is no default program set to open files of that type. Choose “Open with…’, browse to the program to use, and check the box that says to make this the default program from now on (or words to that effect.)
