I recently encountered a nasty bug. Every time I wanted to copy a file with CTRL-C or move it with CTRL-X my explorer on Windows XP SP2 crashed. A right click on the corresponding file or the folder also resulted in a crash.

Using Google, I finally found the solution. The crash was caused by a faulty explorer shell extension.

Removing the corresponding entries from the registry under

HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers

and

HKEY_CLASSES_ROOT\Directory\shellex\ContextMenuHandlers

or

HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers

fixed the error.

Make sure you backup your registry before working on it!

HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
