Windows Explorer slight problem

It something I have no idea how it started or why, but when I first go into Windows Explorer and click on "C" I get
"Windows cannot find chooser.exe "
"This program is needed for opening files of type "File "
"Typoe in an executable to be used instead "
Then follows a C:\
But if I right click I see "Autoplay" at the top, and if I select that I get that stupid message, so therin lies the problem, but how ?
I just select explore, and off it goes, and will not happen till I start up the computer again the following time.
How can i get round this ? Its IRRITATING, even if minor.

 

Do you have an autorun.inf in the root of C: ? If so, try renaming to autorun.old, open My Computer and hit F5 to refresh the window or reboot.

 

It worked !!! You're a genius sir (or lady !) ! I salute you Angel, Ol' bean !
