Regedit.exe does not display value names longer than 255 characters, so if you use Regedit to confirm creation of a value it may appear that creation has failed. Check the return value of RegSetValueEx for ERROR_SUCCESS to confirm successful creation of a value, and use the reg.exe command-line tool to view value names of any length. http://technet.microsoft.com/en-us/library/cc732643(WS.10).aspx

Although there seems to be no default classes for registry keys defined now, what is the maximum size of the registry key class?

256 characters + terminating 0 as for a window class?
