But you could remove items from the right click menu that causes the crash.
Again, Explorer is something unfixable as we have no access to source code. But my bet is your question is not what you are asking for help with.
Here's a link about the context editors -> http://windowsxp.mvps.org/context_folders.htm HINT: GO GET THAT TOOL.
As to the missing CD that's going to be fatal so be sure to find that CD.
I try to right click a desktop or folder icon and get a message that Explorer has encountered an error and must close, at which time my desktop blanks all icons, refreshes and all seems normal. Internet Explorer works, but file viewer does not allow JPEG, BMP or GIF files to be edited. I get the same message as above. I have re-installed IE, upgraded to IE8 and neither selection has affected the outcome. Is there an option other than re-installing Windows. System Restore doesn't solve the problem, it hung up for well over 12 hours and I was forced to restart the computer in safe mode (hoping SR would work, which it didn't.) I have the disks that came with the computer but am hesisitant to use them again, it wiped out all bookmarks, data and favorites. (I can't move them because I have no working right-click options due to the above error.)
