View source for Right click or Ctrl-C causing crash

A faulty Explorer shell extension can cause Total Commander (and other file managers) to crash when right clicking on a file, or when pressing Ctrl+C (copy).

To correct it, please try the following:

1. Start regedit.exe

2. Go to the key
    HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers

In this key, all shell extensions are listed which work with all files.    The * is a real star, it does not mean 'any key' here!

3. Choose "Registry" - "export registry", so you can revert your changes later. Choose to export only the selected branch.

4. Now delete one context menu handler after the other, and then try each time in Total Commander whether Ctrl+C works again. This way you should find the defective extension.

5. When you have found it, you need to double click the .reg-file created above to restore all shell extensions, and then delete only the malfunctioning extension.

You may have to repeat this with the keys
    HKEY_CLASSES_ROOT\Directory\shellex\ContextMenuHandlers
or
    HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers

If the error happens with directories or with virtual folders.
