Windows 7: Windows 7 fails to recognize video files

Windows 7 fails to recognize video files

It seems like ever since i was messing around with Sony Vegas Pro i happened to install a Quick Time plugin for Vegas...Then i got rid of it but something strange occurred...Now every video file (.avi, .mkv, .mpg, .mpeg, wmv ... etc. ) without exceptions is not recognized by the system. Every time i double click such file the screen that allows you to choose how to open the file pops up. Even if i choose the program, let's say KMPlayer and put a tick on 'Always use the selected program to open this kind of file', nothing changes. The video opens, everything works perfect, but the system still does not recognize the file/s. Any suggestions ?

Ok...long story, with whining included. I apologize if this is the wrong forum (no BSOD) but hope it is correct. So the computer wouldn't boot up anymore, the screen had lines on it (which should have been a big hint), safe modes wouldn't work, restore points didn't load, repair and recovery...
