first you have to make sure you don't have any virus.. have you checked ? then, download some sort of spyware and clean your system. Again, go to registry and remove unwanted stuff (applications.exe).
Your file association is messed up, either it is caused by virus or some cheesing shareware program.. there are two solutions:
1- reinstall the operating system.
2- change the file association manually (painful process) ,, open any file, go to Tools / Folder Option / File Type and select a file extension (for example .doc) and then, search for Microsoft word.exe and set the association.
Another way of doing it is,, right click on a file that you want to open, go to "Open With" , then select the program accordingly (by the way there is a check box in there too to allow you to set permanent association.
cheers
p.s,, I hope I did not confuse you
